关于远程Remoting的一个小问题！

[ax711740]

 
            AppDomain child = AppDomain.CreateDomain("ChildDomain");
            child.SetData("PRIVATE_BINPATH", "myBin");
            Console.WriteLine("创建非引用或传值对象");
            ObjectHandle oh = (ObjectHandle)child.CreateInstanceFrom("C:\\aa\\demo.dll", "Demo.MyValueObj");
            try
            {
                object obj = (object)oh.Unwrap();
            }
            catch (Exception e)
            {
                Console.WriteLine(e.Message);
            }

引发异常
未解析成员"Demo.MyValueObj,demo,Version=0.0.0.0,Cultrue=Neutral,PublicKeyToken=null"

但是 ObjectHandle oh = (ObjectHandle)child.CreateInstanceFrom("C:\\aa\\demo.dll", "Demo.MyValueObj");
这句话创建对象成功了（因为我有看到对象的构造函数执行了）
希望各位帮忙看下到底是声明原因引发的异常
Demo.MyValueObj类的内容如下：

using System;
using System.Threading;
namespace Demo
{
         [Serializable]
	class MyValueObj
	{
		int i=0,j=0;
		public MyValueObj()
		{

			 Console.WriteLine("当前应用域名称为：{0}",AppDomain.CurrentDomain.FriendlyName);
		 	 Console.WriteLine("当前线程的代码是：{0}",Thread.CurrentThread.GetHashCode().ToString());
		}
		public void DoSomeWork()
		{
			 Console.WriteLine("我是Demo.MyValueObj对象");
			 Console.WriteLine("当前应用域名称为：{0}",AppDomain.CurrentDomain.FriendlyName);
		 	 Console.WriteLine("当前线程的代码是：{0}",Thread.CurrentThread.GetHashCode().ToString());
		 	 Console.WriteLine("i={0},j={1}",i,j);
		}
	}
}
