使用“Control.CheckForIllegalCrossThreadCalls = false"是个好主意吗?

Is it good idea to use quot;Control.CheckForIllegalCrossThreadCalls = falsequot;(使用“Control.CheckForIllegalCrossThreadCalls = false是个好主意吗?)

问题描述

我有一个从串口接收数据的类.我用 action;委托 将数据传递给在文本框中显示的表单.问题是我无法访问 textbox 控件，因为它说:Cross-thread operation not valid: Control 从创建它的线程以外的线程访问.

I have a class that receives data from serialport. i used action<T> delegate to pass data to the form where it is displayed in a textbox. the thing is i could not access the textbox control, becouse it says: Cross-thread operation not valid: Control accessed from a thread other than the thread it was created on.

所以我设置了 Control.CheckForIllegalCrossThreadCalls = false，它正在工作.

so i set Control.CheckForIllegalCrossThreadCalls = false, and it is working.

这样做是个好主意吗?或者有更好的方法.

is it good idea to do that? or there is a better way of doing it.

谢谢

推荐答案

虽然它看起来大部分时间都可以工作，但它肯定会时不时地失败.

While it may appear to work most of the time, it is sure to fail every now and then.

如果您需要从另一个线程访问/修改 UI 控件，请使用 Control.Invoke.

If you need to access/modify the UI control from another thread, use Control.Invoke.
