C#跨線程存取方法

 

代碼

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);

        }

簡單的：需要提前聲明一個委託：PortNumberReadyEventHandler

 

 

代碼

   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);
            }
        }
