Assembly assembly = null;
string windowsPath = Path.Combine(Application.StartupPath, "Windows");
 
foreach (string dllFile in Directory.GetFiles(windowsPath, "*.dll"))
{
     assembly = Assembly.LoadFile(dllFile);
     Type[] types = assembly.GetTypes();
     foreach (Type t in types)
     {
          //增加你的代码
     }
}
