推荐答案

你不能从任何其他线程调用当前正在执行的UI的任何实例方法或属性那么UI线程。如果需要从这种非UI线程更新UI，则需要使用UI线程调用机制。请查看我过去的答案：

Control.Invoke（ ）与Control.BeginInvoke（） [ ^ ]，

Treeview扫描仪和MD5的问题 [ ^ ]。



我建议永远不要禁用非法跨线程调用的检查。这是不安全的做法。您没有任何严肃的理由使用它。

-SA

You cannot call any instance methods or properties of currently executing UI from any thread other then UI thread. If you need to update UI from such non-UI thread, you need to use UI thread invocation mechanism. Please see my past answers:
Control.Invoke() vs. Control.BeginInvoke()[^],
Problem with Treeview Scanner And MD5[^].

And I would advise to never disable the check for illegal cross-thread calls. This is unsafe practice. You don't have any serious reason to use it.
