在线程内部登录Richtextbox [英] Logging in Richtextbox inside thread

问题描述

大家好

好的，这一定是最愚蠢的选择，但我只是不明白.

我有WPF用户界面，其中有richtextbox"myLog".我也时不时地获取数据，这可能需要记录.当我的事件调用我的Log方法时，我收到错误消息:

调用线程无法访问该对象，因为其他线程拥有它"

这是我的logmethod的简化的想法:

Hi all

Okay, this must be some kind of monkeytest, but I just dont get it.

I have WPF UI where I have richtextbox "myLog". Also I get data now and then which could need logging. When my event call my Log method I receive error:

"The calling thread cannot access this object because a different thread owns it"

And here is simplified idea of my logmethod:

//LogMsgType msgtype: Error/Incoming/Normal/Outgoing,Warning , string msg: message 
private void Log(LogMsgType msgtype, string msg)
        {
        myLog.AppendText(msg); //here error occurs 
        }

我真的很感谢您的建议:)

i really appreciate your advices :)

推荐答案

您需要在此处执行Invoke()，因为文本框与尝试更新文本框的线程不同.

这应该为您指明正确的方向:

You need to do an Invoke() here because the textbox is owned by a different thread than the one trying to update it.

This should point you in the right direction:
