利用SignalR实现聊天室（进阶篇）

实现web与窗体程序通信聊天

在原来的基础上代码保持不变，窗体程序负责交互

  public partial class Form1 : Form
    {
        string url = "http://localhost:10319";
        HubConnection _conn;
        IHubProxy _proxy;
        string username = "wdd3";
        public Form1()
        {
            InitializeComponent();
            CheckForIllegalCrossThreadCalls = false;
           
        }
        private void Form1_Load(object sender, EventArgs e)
        {
            _conn = new HubConnection(url, true);
            _proxy = _conn.CreateHubProxy("MyHub");
            _conn.Start();
            setlogin();
        }
        private void setlogin()
        {
            _conn.StateChanged += new Action<StateChange>(tgt =>
            {
                if (((StateChange)tgt).NewState == Microsoft.AspNet.SignalR.Client.ConnectionState.Connected)
                {
                    //客户端调用服务端的 Send() 方法,传入参数"Hello"         
                    _proxy.Invoke("SendLogin", "wdd3");
                }
            });

            //定义客户端的方法sendMessage()(有两个string类型的参数，当服务端调用sendMessage,需要传入2个string类型参数),以这种格式定义方法服务端才能去调用
            _proxy.On<string>("sendMessage123", rebackdata);
            _proxy.On<string>("sendMessage_Persion", setmsg);
        }

      

        private void button1_Click(object sender, EventArgs e)
        {

          
        }

        public void rebackdata(string s)
        {
            textBox3.Text =s.ToString();
        }
        public void setmsg(string s)
        {
            textBox4.Text = s.ToString();
        }

        private void button2_Click(object sender, EventArgs e)
        {
            _proxy.Invoke("SendByGroup", username, textBox2.Text, textBox1.Text);
            //_conn.StateChanged += new Action<StateChange>(tgt =>
            //{
            //    if (((StateChange)tgt).NewState == Microsoft.AspNet.SignalR.Client.ConnectionState.Connected)
            //    {
            //        //客户端调用服务端的 Send() 方法,传入参数"Hello"         
                   
            //    }
            //});
            
        }
    }

效果如下：
