如何在该事件的另一个实例被触发之前完成一个事件C＃ [英] How to complete a event before another instance of that event gets fired C#

问题描述

我在点击事件被触发时执行特定操作。

如果用户在现有事件完成后连续点击该按钮控件，则会调用新事件。因此我的操作失败了。



我试图保留一个标志来执行此操作但是一旦标志被激活，新实例就会被激活。



有没有办法解决这个问题。

I am performing a particular operation when a click event is fired.
If a user continuously clicks that button control as soon as the existing event finishes the new event gets called. Hence my operation fails.

I tried keeping a flag to do this but as soon the flag gets activated the new instance gets activated.

Is there any way to solve this.

推荐答案

您可以在事件处理程序的最开头禁用该按钮并再次启用它操作完成后。

You could disable the button at the very beginning of the event handler and enable it again when the operation is completed.
