代码
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
代码
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);
}
}
