Detectar a versão do Windows em .net

Como posso detectar as versões do sistema operacional Windows no .net?

Qual código posso usar?

System.Environment.OSVersionpossui as informações necessárias para distinguir a maioria das principais versões do sistema operacional Windows, mas não todas. Consiste em três componentes que são mapeados para as seguintes versões do Windows:

+------------------------------------------------------------------------------+
|                    |   PlatformID    |   Major version   |   Minor version   |
+------------------------------------------------------------------------------+
| Windows 95         |  Win32Windows   |         4         |          0        |
| Windows 98         |  Win32Windows   |         4         |         10        |

Para uma biblioteca que permita obter uma visão mais completa da versão exata do Windows em que o ambiente de execução atual está sendo executado, consulte esta biblioteca .

Nota importante : se o manifesto do assembly executável não declarar explicitamente que o assembly exe é compatível com o Windows 8.1 e o Windows 10.0, System.Environment.OSVersionretornará a versão do Windows 8, que é 6.2, em vez de 6.3 e 10.0! Fonte: aqui .

Eu usei isso quando tive que determinar várias versões do sistema operacional Microsoft:

string getOSInfo()
{
   //Get Operating system information.
   OperatingSystem os = Environment.OSVersion;
   //Get version information about the os.
   Version vs = os.Version;

   //Variable to hold our return value
   string operatingSystem = "";

   if (os.Platform == PlatformID.Win32Windows)
   {
       //This is a pre-NT version of Windows
       switch (vs.Minor)
       {
           case 0:
               operatingSystem = "95";
               break;
           case 10:
               if (vs.Revision.ToString() == "2222A")
                   operatingSystem = "98SE";
               else
                   operatingSystem = "98";
               break;
           case 90:
               operatingSystem = "Me";
               break;
           default:
               break;
       }
   }
   else if (os.Platform == PlatformID.Win32NT)
   {
       switch (vs.Major)
       {
           case 3:
               operatingSystem = "NT 3.51";
               break;
           case 4:
               operatingSystem = "NT 4.0";
               break;
           case 5:
               if (vs.Minor == 0)
                   operatingSystem = "2000";
               else
                   operatingSystem = "XP";
               break;
           case 6:
               if (vs.Minor == 0)
                   operatingSystem = "Vista";
               else if (vs.Minor == 1)
                   operatingSystem = "7";
               else if (vs.Minor == 2)
                   operatingSystem = "8";
               else
                   operatingSystem = "8.1";
               break;
           case 10:
               operatingSystem = "10";
               break;
           default:
               break;
       }
   }
   //Make sure we actually got something in our OS check
   //We don't want to just return " Service Pack 2" or " 32-bit"
   //That information is useless without the OS version.
   if (operatingSystem != "")
   {
       //Got something.  Let's prepend "Windows" and get more info.
       operatingSystem = "Windows " + operatingSystem;
       //See if there's a service pack installed.
       if (os.ServicePack != "")
       {
           //Append it to the OS name.  i.e. "Windows XP Service Pack 3"
           operatingSystem += " " + os.ServicePack;
       }
       //Append the OS architecture.  i.e. "Windows XP Service Pack 3 32-bit"
       //operatingSystem += " " + getOSArchitecture().ToString() + "-bit";
   }
   //Return the information we've gathered.
   return operatingSystem;
}

Eu uso o ManagementObjectSearcherespaço para nomeSystem.Management

Exemplo:

string r = "";
using (ManagementObjectSearcher searcher = new ManagementObjectSearcher("SELECT * FROM Win32_OperatingSystem"))
{
    ManagementObjectCollection information = searcher.Get();
    if (information != null)
    {
        foreach (ManagementObject obj in information)
        {
            r = obj["Caption"].ToString() + " - " + obj["OSArchitecture"].ToString();
        }
    }
    r = r.Replace("NT 5.1.2600", "XP");
    r = r.Replace("NT 5.2.3790", "Server 2003");
    MessageBox.Show(r);
}

Não se esqueça de adicionar a referência à montagem System.Management.dll e colocar o uso:using System.Management;

Documentação

Como R. Bemrose sugeriu, se você estiver executando recursos específicos do Windows 7, consulte o Windows® API Code Pack para Microsoft® .NET Framework .

Ele contém uma CoreHelpersclasse que permite determinar o sistema operacional em que você está atualmente (apenas XP e superior, é um requisito para o .NET atualmente)

Ele também fornece vários métodos auxiliares. Por exemplo, suponha que você queira usar a lista de atalhos do Windows 7, existe uma classe TaskbarManagerque fornece uma propriedade chamada IsPlatformSupportede ela retornará true se você estiver no Windows 7 e acima.

Você pode usar esta classe auxiliar;

Via Environment.OSVersionqual "Obtém um objeto System.OperatingSystem que contém o identificador da plataforma atual e o número da versão".

Todas parecem respostas muito complicadas para uma função muito simples:

public bool IsWindows7 
{ 
    get 
    { 
        return (Environment.OSVersion.Version.Major == 6 &
            Environment.OSVersion.Version.Minor == 1); 
    } 
}

Detectar a versão do SO:

    public static string OS_Name()
    {
        return (string)(from x in new ManagementObjectSearcher(
            "SELECT Caption FROM Win32_OperatingSystem").Get().Cast<ManagementObject>() 
            select x.GetPropertyValue("Caption")).FirstOrDefault();
    }

Essa é uma pergunta relativamente antiga, mas recentemente tive que resolver esse problema e não vi minha solução publicada em nenhum lugar.

A maneira mais fácil (e mais simples, na minha opinião) é usar apenas uma chamada pinvoke para RtlGetVersion

[DllImport("ntdll.dll", SetLastError = true)]
internal static extern uint RtlGetVersion(out Structures.OsVersionInfo versionInformation); // return type should be the NtStatus enum

[StructLayout(LayoutKind.Sequential)]
internal struct OsVersionInfo
{
    private readonly uint OsVersionInfoSize;

    internal readonly uint MajorVersion;
    internal readonly uint MinorVersion;

    private readonly uint BuildNumber;

    private readonly uint PlatformId;

    [MarshalAs(UnmanagedType.ByValTStr, SizeConst = 128)]
    private readonly string CSDVersion;
}

Onde os números de versão Maior e Menor nesta estrutura correspondem aos valores na tabela da resposta aceita.

Isso retorna o número de versão correto do Windows, diferente das funções obsoletas GetVersion & GetVersionEx do kernel32

1. Adicione referência a Microsoft.VisualBasic.
2. Incluir espaço para nome using Microsoft.VisualBasic.Devices;
3. Usar new ComputerInfo().OSFullName

O valor de retorno é "Microsoft Windows 10 Enterprise"

Mão única:

public string GetOSVersion()
{
  int _MajorVersion = Environment.OSVersion.Version.Major;

  switch (_MajorVersion) {
    case 5:
      return "Windows XP";
    case 6:
      switch (Environment.OSVersion.Version.Minor) {
        case 0:
          return "Windows Vista";
        case 1:
          return "Windows 7";
        default:
          return "Windows Vista & above";
      }
      break;
    default:
      return "Unknown";
  }
}

Em seguida, basta envolver um caso de seleção em torno da função.

Que tal usar um registro para obter o nome.

"HKEY_LOCAL_MACHINE \ SOFTWARE \ Microsoft \ Windows NT \ CurrentVersion" tem um valor ProductName desde o Windows XP.

[DllImport("kernel32.dll")]
static extern IntPtr GetCurrentProcess();

[DllImport("kernel32.dll")]
static extern IntPtr GetModuleHandle(string moduleName);

[DllImport("kernel32")]

[DllImport("kernel32.dll")]
static extern bool IsWow64Process(IntPtr hProcess, out bool wow64Process);

public static bool Is64BitOperatingSystem()
{
    // Check if this process is natively an x64 process. If it is, it will only run on x64 environments, thus, the environment must be x64.
    if (IntPtr.Size == 8)
        return true;
    // Check if this process is an x86 process running on an x64 environment.
    IntPtr moduleHandle = GetModuleHandle("kernel32");
    if (moduleHandle != IntPtr.Zero)
    {
        IntPtr processAddress = GetProcAddress(moduleHandle, "IsWow64Process");
        if (processAddress != IntPtr.Zero)
        {
            bool result;
            if (IsWow64Process(GetCurrentProcess(), out result) && result)
                return true;
        }
    }
    // The environment must be an x86 environment.
    return false;
}

private static string HKLM_GetString(string key, string value)
{
    try
    {
        RegistryKey registryKey = Registry.LocalMachine.OpenSubKey(key);
        return registryKey?.GetValue(value).ToString() ?? String.Empty;
    }
    catch
    {
        return String.Empty;
    }
}

public static string GetWindowsVersion()
{
    string osArchitecture;
    try
    {
        osArchitecture = Is64BitOperatingSystem() ? "64-bit" : "32-bit";
    }
    catch (Exception)
    {
        osArchitecture = "32/64-bit (Undetermined)";
    }
    string productName = HKLM_GetString(@"SOFTWARE\Microsoft\Windows NT\CurrentVersion", "ProductName");
    string csdVersion = HKLM_GetString(@"SOFTWARE\Microsoft\Windows NT\CurrentVersion", "CSDVersion");
    string currentBuild = HKLM_GetString(@"SOFTWARE\Microsoft\Windows NT\CurrentVersion", "CurrentBuild");
    if (!string.IsNullOrEmpty(productName))
    {
        return
            $"{productName}{(!string.IsNullOrEmpty(csdVersion) ? " " + csdVersion : String.Empty)} {osArchitecture} (OS Build {currentBuild})";
    }
    return String.Empty;
}

Se você estiver usando o .NET Framework 4.0 ou superior. Você pode remover o método Is64BitOperatingSystem () e usar Environment.Is64BitOperatingSystem .

Primeira solução

Para garantir que você obtenha a versão correta Environment.OSVersion, adicione um app.manifestusando o Visual Studio e remova o comentário das seguintes supportedOStags:

  <compatibility xmlns="urn:schemas-microsoft-com:compatibility.v1">
    <application>
      <!-- A list of the Windows versions that this application has been tested on
           and is designed to work with. Uncomment the appropriate elements
           and Windows will automatically select the most compatible environment. -->

      <!-- Windows Vista -->
      <supportedOS Id="{e2011457-1546-43c5-a5fe-008deee3d3f0}" />

      <!-- Windows 7 -->
      <supportedOS Id="{35138b9a-5d96-4fbd-8e2d-a2440225f93a}" />

      <!-- Windows 8 -->
      <supportedOS Id="{4a2f28e3-53b9-4441-ba9c-d69d4a4a6e38}" />

      <!-- Windows 8.1 -->
      <supportedOS Id="{1f676c76-80e1-4239-95bb-83d0f6d0da78}" />

      <!-- Windows 10 -->
      <supportedOS Id="{8e0f7a12-bfb3-4fe8-b9a5-48fd50a15a9a}" />

    </application>
  </compatibility>

Então, no seu código, você pode usar Environment.OSVersionassim:

var version = System.Environment.OSVersion;
Console.WriteLine(version);

Exemplo

Por exemplo, em meu Windows 10.0 Build 18362.476resultado machine ( ) seria assim, o que está incorreto :

Microsoft Windows NT 6.2.9200.0

Ao adicionar app.manifeste descomentar essas tags , obteremos o número da versão correta:

Microsoft Windows NT 10.0.18362.0

Solução alternativa

Se você não gosta de adicionar app.manifestao seu projeto, pode usar o OSDescriptionque está disponível desde o .NET Framework 4.7.1 e .NET Core 1.0.

string description = RuntimeInformation.OSDescription;

Nota: Não esqueça de adicionar a seguinte declaração using no topo do seu arquivo.

using System.Runtime.InteropServices;

As respostas acima me dariam a Majorversão 6no Windows 10.

A solução que eu encontrei para trabalhar sem adicionar bibliotecas VB extras foi a seguinte:

var versionString = (string)Microsoft.Win32.Registry.LocalMachine.OpenSubKey("Software\\Microsoft\\Windows NT\\CurrentVersion")?.GetValue("productName");

Eu não consideraria essa a melhor maneira de obter a versão, mas o lado positivo disso é que não há bibliotecas extras e, no meu caso, verificar se ela contém "10"foi boa o suficiente.

Não complique demais o problema.

string osVer = System.Environment.OSVersion.Version.ToString();

if (osVer.StartsWith("5")) // windows 2000, xp win2k3
{
    MessageBox.Show("xp!");
}
else // windows vista and windows 7 start with 6 in the version #
{
    MessageBox.Show("Win7!");
}
