c# 接收网络汉字乱码_C# : Socket 接收中文显示乱码的解决办法

由 Programming C# 3.0 示例改编

AsyncNetClient.cs

using System;

using System.Collections.Generic;

using System.IO;

using System.Net.Sockets;

using System.Text;

namespace AsyncNetClient

{

public class AsynchNetworkClient

{

private NetworkStream streamToServer;

static public int Main()

{

string str;

Console.Write("input:");

str = Console.ReadLine();

if (str.Length > 20)

{

Console.WriteLine("提示: 输入字符串长度 <= 20");

return 4;

}

AsynchNetworkClient client = new AsynchNetworkClient("localhost",65000);

if( client != null && str!=null) return client.Run(str);

else return 4;

}

public AsynchNetworkClient(string ip, int port)

{

string serverName = ip;

try

{

Console.WriteLine("Connecting to {0}", serverName);

TcpClient tcpSocket = new TcpClient(serverName, port);

streamToServer = tcpSocket.GetStream();

}

catch (Exception e){

Console.WriteLine(e.ToString());

}

}

public int Run(string str)

{

if (streamToServer == null)

{

Console.WriteLine("connect to Server failed !");

return -1;

}

string message;

if( str != "") message= str;

else return -1;

Console.WriteLine("Send to server: {0}", message);

// create a streamWriter and use it to

// write a string to the server

StreamWriter writer = new StreamWriter(streamToServer);

writer.WriteLine(message);

writer.Flush();

// 使用System.Text.Encoding.Default 告诉 StreamReader采用目前操作系统的编码即可

StreamReader reader = new StreamReader(streamToServer,Encoding.Default);

string strResponse = reader.ReadLine();

streamToServer.Close();

Console.WriteLine("Received: {0}", strResponse);

return 0;

}

}

}
