这是好主意，用" Control.CheckForIllegalCrossThreadCalls = FALSE" [英] Is it good idea to use "Control.CheckForIllegalCrossThreadCalls = false"

问题描述

我有一个的serialport从接收数据的类。我用动作< T>代表将数据传递给它显示在一个文本框的形式。事情是我不能访问文本控制，becouse它说：跨线程操作无效：控制距离小于线程以外的线程访问它是在创建。

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 Control.CheckForIllegalCrossThreadCalls = FALSE ，和这是工作。

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

是好主意，这样做呢？或者有这样做的更好的方法。

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

感谢

推荐答案

虽然它可能会出现工作的大部分时间，这是肯定现在再失败每一个。

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

如果你需要从另一个线程访问/修改UI控件，使用 Control.Invoke 。

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