Normal Framework

If it is a .NET DLL you can use Reflection.

using System.Reflection;

Assembly assembly = Assembly.LoadFrom("\x\y\z.dll");
Version ver = assembly.GetName().Version;

If not, you can use System.Diagnostics:

using System.Diagnostics;

static string GetDllVersion(string dllPath)
{
  FileVersionInfo myFileVersionInfo = FileVersionInfo.GetVersionInfo(dllPath);
  return myFileVersionInfo.FileVersion;
}

// Sample invokation
string result = GetDllVersion(@"C:\Program Files (x86)\Google\Chrome\Application\20.0.1132.57\chrome.dll");
// result value **20.0.1132.57**

Compact Framework

If you are using .NET Compact Framework you don't have access to FileVersionInfo
