(.NET C#) อยากถามการเช็คว่าโปรแกรมเปิดอยู่หรือเปล่า C# Window Application ค่ะ

   Process p = Process.GetCurrentProcess();
    string assemblyName = p.ProcessName + ".exe";
    Console.WriteLine("Examining : {0}", assemblyName);
    Assembly a = Assembly.LoadFrom(assemblyName);

    Type[] types = a.GetTypes();
    foreach(Type t in types)
    {
      Console.WriteLine("\nType : {0}",t.FullName);
      Console.WriteLine("\tBase class : {0}",t.BaseType.FullName);
    }
