C#跨线程访问方法

 

        private delegate void WriteToRbxMsgHandle(string msg, bool isError);
        private void WriteToRbxMsg(string msg,bool isError)
        {
            if (!this.rbxWorkingMsg.InvokeRequired)
            {
                WriteToRbxMsgDMethod(msg, isError);
            }
            else
            {
                this.rbxWorkingMsg.Invoke(new WriteToRbxMsgHandle(WriteToRbxMsgDMethod), msg, isError);
            } 
 
        }

        private void WriteToRbxMsgDMethod(string msg, bool isError)
        {
            if (isError)
            {
                this.rbxWorkingMsg.SelectionColor = Color.Red;
            }
            else
            {
                this.rbxWorkingMsg.SelectionColor = Color.Black;
            }
            this.rbxWorkingMsg.SelectedText = msg + "\n";
            this.rbxWorkingMsg.Focus();
            this.rbxWorkingMsg.Select(this.rbxWorkingMsg.Text.Length, 0);

        }

简单的：需要提前声明一个委托：PortNumberReadyEventHandler

 

 

   void tcpReceiver_PortNumberReady(object Sender, PortNumberReadyEventArgs PNR)
        {
            if(this.InvokeRequired)
            {
                PortNumberReadyEventHandler del = delegate(object sender, PortNumberReadyEventArgs pnr)
                {
                    this.Text += pnr.PortNum.ToString();
                };
                this.Invoke(del ,this,PNR);
            }
        }
