为什么我的服务端起动后,我用一个客户端连上可以正常互发消息,而当我这客户端刚一关闭,服务段就出现异常"System.io.ioexception:无法从传输连接中读取数据.--->System.net.sockets.socketexception:你的主机中的软件放弃了一个已建立的连接"报错?

1。顶楼的错误应该是你没有关闭文件读取流的异常,是IO的显然不是线程方面的问题。在客户端断开连接的时候要将streamWriter,streamReader 关闭,有客户端的时候重新再建。
2。你的p2p的乱嘛是你再向数据流中写入的数据没有进行正确编码。
string msg="<"+this.textBox2.Text+"> 说:"+this.richTextBox1.Text+"\n";
//这里要添加:byte[] sendname=System.Text.Encoding.UTF8.GetBytes(msg);
TcpClient tcpClient=new TcpClient(textBox1.Text,8888);
NetworkStream tcpStream=tcpClient.GetStream();
streamWriter streamW=new StreamWriter(tcpStream);
//这里改为:
streamW.Write(sendname,0,sendname.Length);//下面不变
