TcpClient在form2里发送给服务器请求时遇到问题有一个客户端的FORM,一个登陆按钮的click事件: 
private void button4_Click(object sender, EventArgs e) 

    sendmsg = "#submit#username#" + textBox4.Text + "#password#" + textBox3.Text + "#"; 
    _netcnn = new Thread(new ThreadStart(chkusr)); 
    _netcnn.Start(); 
    chkflag = 0;
             while (chkflag==0)
            {
                continue;
            }
            _netcnn.Interrupt();
            if (chkflag==1)
            {
                Form2 f2 = new Form2();
                f2.f1 = this;
                f2.Show();
                this.Visible=false;
            }
            if (chkflag == 2)
            {
                MessageBox.Show("登陆失败,请检查用户名、密码!");
            }

chkusr方法的代码: 
private void chkusr() 

    Ccs = new Connectclass(); 
    Boolean flag1 = Ccs.connect(); 
    if (flag1 == false) 
    { 
        MessageBox.Show("连接服务器失败,请检查网络连接"); 
        chkflag = 3; 
        return; 
    } 
    bool returnflag; 
    returnflag= Ccs.CheckUser(sendmsg); 
    if (returnflag == true) 
    { 
        chkflag = 1; 
    } 
    else 
    { 
        chkflag = 2; 
    } 

这里的 
Ccs.connect()方法是: 
        public Boolean connect() 
        { 
            try 
            { 
                myclient = new TcpClient("192.168.1.3", 1234); 
                myclient.ReceiveTimeout = 100; 
                networkStream=myclient.GetStream(); 
                 
                streamReader = new StreamReader(networkStream); 
                streamWriter = new StreamWriter(networkStream); 
            } 
            catch 
            { 
                return false; 
            } 
            return true; 
        } form2的load事件
private void Form2_Load(object sender, EventArgs e)
        {
            string initialization = f1.Ccs.Sendcommand("#initialization#");
            //string initialization = f1.turnmsg;
            if (initialization == "false")
            {
                MessageBox.Show("Server disconnected");
            }
            else
            {
            ……
              }
         }这里的Sendcommand事件代码是:
public string Sendcommand(string Command)
        {
            try
            {                
                string msg=Command;
                streamWriter.WriteLine(msg);
                  streamWriter.Flush();
            }
            catch (Exception ee)
            {
                return "false";
            }
            string reseavemsg="";
            try
             {
                bool flag=true;
                 while (flag)
                {
                    reseavemsg = streamReader.ReadLine();
                    if (reseavemsg != "")
                    {
                        flag = false;
                    }
                }
            }
            catch (Exception ee)
            {
                MessageBox.Show(ee.ToString());
                return "false";
            }
            return reseavemsg;
        }现在的问题是,在form1里面是可以通过认证的,然后启动form2,在form2的load事件里需要一个Sendcommand事件,来请求服务端发送初始化信息,但是现在Sendcommand发送的#initialization#信息服务端根本就收不到,单步执行到streamread时,就出Exception了,不知道是不是因为在form1里面启动过连接的新线程,在线程中断以后需要重新连接,还是什么回事,大家帮帮忙啦~谢谢谢谢
