服务器发送一条数据如：
Java代码
BufferedReader in = new BufferedReader(new InputStreamReader(client.getInputStream()));
PrintWriter out = new PrintWriter(client.getOutputStream());
out.println("没有查到该数据。");//向客户端发送
out.flush();

BufferedReader in = new BufferedReader(new InputStreamReader(client.getInputStream()));
PrintWriter out = new PrintWriter(client.getOutputStream());
out.println("没有查到该数据。");//向客户端发送
out.flush();

然后客户端接收：
Java代码
public BufferedReader recieve(){
        //从服务端程序接收数据
        InputStreamReader isr=null;
        BufferedReader br=null;
        try {
            isr = new InputStreamReader(server.getInputStream());//这里需要GBK
            br = new BufferedReader(isr);
        } catch (IOException e) {
            // TODO Auto-generated catch block
            e.printStackTrace();
        }
        return br;
}
///////////////////////////////////////
BufferedReader br=recieve();
while((message = br.readLine()) != null){
    messages+=message;
}
System.out.println("messages="+messages);

public BufferedReader recieve(){
   //从服务端程序接收数据
   InputStreamReader isr=null;
   BufferedReader br=null;
   try {
    isr = new InputStreamReader(server.getInputStream());//这里需要GBK
    br = new BufferedReader(isr);
   } catch (IOException e) {
    // TODO Auto-generated catch block
    e.printStackTrace();
   }
   return br;
}
///////////////////////////////////////
BufferedReader br=recieve();
while((message = br.readLine()) != null){
messages+=message;
}
System.out.println("messages="+messages);

你会发现这样写会是乱码；
应该写成isr = new InputStreamReader(server.getInputStream(),"GBK");
这样就正常显示了。
在服务端默认的编码情况下，JAVA的SOCKET接收需要GBK编码，而C#的接收需要UTF-8编码
