如何从另一个appDomain调用类的方法

Question

my application want to call a method of a class that is from another AppDomain.

       AppDomain env = AppDomain.CreateDomain(
            "test",
            null,
            new AppDomainSetup() { ApplicationName = "test" }
            );

        Assembly a = Assembly.LoadFrom("d:\\testenv1\\test2.dll");
        //env.AssemblyResolve += new ResolveEventHandler(env_AssemblyResolve);
        env.Load(a.FullName);

        ObjectHandle o = env.CreateInstance(a.FullName, "Test2.Class1");

now i have the object handle of the Test2.Class1, but i have no idea how to invode the "action" method of the Class1 class.

the "action" method likes this:

    public void action()
    {
        Console.WriteLine(AppDomain.CurrentDomain.FriendlyName + " ok");
    }

i tried to use o.unwrap() method to get the reference of the object, but it seems the object has been transferred into the current domain, so the output of the "action" method prints the current domain name.
