如何在控制台应用程序中获取 AppDomain.CurrentDomain.ActivationContext 的 object？

Question

using System;
namespace ActivationContextSample
{
 public class Program : MarshalByRefObject
 {
    public static void Main(string[] args)
    {
        ActivationContext ac = AppDomain.CurrentDomain.ActivationContext;
        ApplicationIdentity ai = ac.Identity;
        Console.WriteLine("Full name = " + ai.FullName);
        Console.WriteLine("Code base = " + ai.CodeBase);
        Console.Read();
    }
    public void Run()
    {
        Main(new string[] { });
        Console.ReadLine();
    }
}

}

Answer 1

如果设置断点，您应该能够看到 AppDomain.CurrentDomain.ActivationContext 为空。

Answer 2

Try creating executable application and run it. In that case you will get the required object.
