Kris, sua versão funciona muito bem quando é necessário carregar o assembly a partir do arquivo DLL real (e se a DLL estiver lá!), No entanto, ocorrerá um erro indesejado se a DLL for EMBEDDED (ou seja, não um arquivo, mas um arquivo incorporado DLL).
A outra coisa é que, se alguém usa um esquema de versão com algo como " 1.2012.0508.0101 ", quando alguém obtém a string da versão, você realmente obtém " 1.2012.518.101 "; observe os zeros ausentes .
Então, aqui estão algumas funções extras para obter a versão de uma DLL (incorporada ou do arquivo DLL):

{
System.Reflection.Assembly tMyAssembly = null;
if (string.IsNullOrEmpty(pAssemblyName)) { return tMyAssembly; }
tMyAssembly = GetAssemblyEmbedded(pAssemblyName);
if (tMyAssembly == null) { GetAssemblyDLL(pAssemblyName); }
return tMyAssembly;
}//System.Reflection.Assembly GetAssemblyEmbedded(string pAssemblyDisplayName)
public static System.Reflection.Assembly GetAssemblyEmbedded(string pAssemblyDisplayName)
{
System.Reflection.Assembly tMyAssembly = null;
if(string.IsNullOrEmpty(pAssemblyDisplayName)) { return tMyAssembly; }
try //try #a
{
tMyAssembly = System.Reflection.Assembly.Load(pAssemblyDisplayName);
}// try #a
catch (Exception ex)
{
string m = ex.Message;
}// try #a
return tMyAssembly;
}//System.Reflection.Assembly GetAssemblyEmbedded(string pAssemblyDisplayName)
public static System.Reflection.Assembly GetAssemblyDLL(string pAssemblyNameDLL)
{

if (!pAssemblyNameDLL.ToLower().EndsWith(".dll")) { pAssemblyNameDLL += ".dll"; }
tMyAssembly = System.Reflection.Assembly.LoadFrom(pAssemblyNameDLL);
}// try #a
catch (Exception ex)
{
string m = ex.Message;
}// try #a
return tMyAssembly;
}//System.Reflection.Assembly GetAssemblyFile(string pAssemblyNameDLL)
public static string GetVersionStringFromAssembly(string pAssemblyDisplayName)
{

{

return tVersion;
}//string GetVersionString(Version pVersion)
public static string GetVersionString(string pVersionString)
{

string[] aVersion;
if (string.IsNullOrEmpty(pVersionString)) { return tVersion; }
aVersion = pVersionString.Split('.');

{

return tVersion;
}//string GetVersionStringFromAssemblyEmbedded(string pAssemblyDisplayName)
public static string GetVersionStringFromAssemblyDLL(string pAssemblyDisplayName)
{
