高手帮我看看吧
当服务端启动正常，当启动客户端时就会出现下图的错误：
下面是错误信息：
未处理 System.ArgumentNullException
Message="值不能为空。\r\n参数名: source"
Source="mscorlib"
ParamName="source"
StackTrace:
在 System.Runtime.InteropServices.Marshal.CopyToManaged(IntPtr source, Object destination, Int32 startIndex, Int32 length)

--------------------编程问答-------------------- 异常窗口把代码挡住了～看不到你那source在哪。。。 --------------------编程问答-------------------- Server.cs的代码：
//就这几行代码还找不到错误吗,
//看看参数传值,设置断点调试一下.

}
//object[] attrs = { new UrlAttribute("tcp://localhost:8085/Hello") };

if (lease != null)
{
Console.WriteLine("Lease Configuration:");
Console.WriteLine("InitialLeaseTime: " +

lease.RenewOnCallTime);
Console.WriteLine("SponsorshipTimeout: " +
lease.SponsorshipTimeout);
Console.WriteLine(lease.CurrentLeaseTime);
}
}
}
}
HelloServer.cs的代码：
using System;--------------------编程问答-------------------- return "Hi there " + name;
using System.Collections.Generic;
using System.Text;
using System.Runtime.Remoting.Lifetime;
namespace RemotingSamples
{
public class HelloServer : MarshalByRefObject
{
public HelloServer()
{
Console.WriteLine("HelloServer activated");
}
public String HelloMethod(String name)
{
Console.WriteLine(
"Server Hello.HelloMethod : {0}", name);
return "Hi there " + name;
}
}
}
name 为何物??
补充：.NET技术 , C#
