关于c# remonting的问题

Question

服务端代码：

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Runtime.Remoting.Channels;
using System.Runtime.Remoting.Channels.Tcp;
using System.Runtime.Remoting;
using System.Collections;
using System.Runtime.Serialization.Formatters;
using Microsoft.Office.Interop.Excel;

[Serializable]
public class DemoClass : MarshalByRefObject
{
    public void Doit()
    {
        Microsoft.Office.Interop.Excel.Application excelapp = new Microsoft.Office.Interop.Excel.Application();
        excelapp.Visible = true;
        Workbook book1 = excelapp.Workbooks.Add(Type.Missing);
        Worksheet sheet1 = (Worksheet)book1.Sheets[1];
        Range range = sheet1.get_Range("A1", Type.Missing);
        range.Value2 = "Hello World!"; 
    }
}
class Program
{
    static void Main(string[] args)
    {
        BinaryServerFormatterSinkProvider provider = new BinaryServerFormatterSinkProvider();
        provider.TypeFilterLevel = System.Runtime.Serialization.Formatters.TypeFilterLevel.Full;
        IDictionary props = new Hashtable();
        props["port"] = 1234;
        ChannelServices.RegisterChannel(new TcpChannel(props, null, provider), false);
        RemotingConfiguration.RegisterWellKnownServiceType(typeof(DemoClass), "DemoClass", WellKnownObjectMode.Singleton);
        Console.WriteLine("服务已启动...");
        Console.ReadKey();
    }
}

客户端代码：

using System.Text;
using System.Runtime.Remoting.Channels;
using System.Runtime.Remoting.Channels.Tcp;
using System.Runtime.Remoting;
using Microsoft.Office.Interop.Excel;

[Serializable]
public class DemoClass : MarshalByRefObject
{
    public void Doit()
    {
    }
}
class Program
{
    static void Main(string[] args)
    {
        DemoClass obj = (DemoClass)Activator.GetObject(typeof(DemoClass), "tcp://127.0.0.1:1234/DemoClass");
        obj.Doit();
        Console.ReadKey();
    }
}

代码在本机测试是没问题的，两者都是控制台应用程序，可以实现功能；但放在局域网中测试问题就来了 ，先执行服务端所在电脑，客户端所在电脑运行之后居然在服务端电脑上打开了Excel，这个不是我要的效果撒。我需要实现客户端远程调用服务端的方法，在客户端电脑上打开Excel

Answer 1

你想让客户端打开excel 那不是应该再客户端里建立一个domoclass的实例化对象来调用doit吗
你直接remonting服务端的对象，自然是在服务端进行操作

using System.Text;
using System.Runtime.Remoting.Channels;
using System.Runtime.Remoting.Channels.Tcp;
using System.Runtime.Remoting;
using Microsoft.Office.Interop.Excel;
 
[Serializable]
public class DemoClass : MarshalByRefObject
{
    public void Doit()
    {
        Microsoft.Office.Interop.Excel.Application excelapp = new Microsoft.Office.Interop.Excel.Application();
        excelapp.Visible = true;
        Workbook book1 = excelapp.Workbooks.Add(Type.Missing);
        Worksheet sheet1 = (Worksheet)book1.Sheets[1];
        Range range = sheet1.get_Range("A1", Type.Missing);
        range.Value2 = "Hello World!"; 
    }
}
class Program
{
    static void Main(string[] args)
    {
        DemoClass obj = (DemoClass)Activator.GetObject(typeof(DemoClass), "tcp://127.0.0.1:1234/DemoClass");
        DemoClass obj2=new DemoClass();
        obj2.doit();
        Console.ReadKey();
    }
}

这样本就是本地打开了吗
