C＃中的Keydown事件问题 [英] Keydown event problem in C#

问题描述

我的问题是我使用按键事件，但在按键e.KeyCode == Keys.E&& e.Control正常工作但e.KeyCode == Keys.N&& e.Control不工作为什么它只能用Cntrl + shift + N plz帮助我



我尝试了什么：



e.KeyCode == Keys.N&& e.Control

My problem is that I use key down event but in key down "e.KeyCode == Keys.E && e.Control" is working proper but "e.KeyCode == Keys.N && e.Control" is not working Why its working only with Cntrl+shift+N plz help me

What I have tried:

"e.KeyCode == Keys.N && e.Control"

推荐答案

它的工作原理对我来说很好：

It works fine for me:

private void frmTest_KeyDown(object sender, KeyEventArgs e)
    {
    if (e.KeyCode == Keys.N && e.Control)
        {
        Console.WriteLine("CTRL+N");
        }
    }

猜测，你没有将KeyPreview设置为true，或者你有一个快捷键分配给CTRL + E或CTRL + N，它们优先获得。



如果这没有帮助，我们将需要更多关于您如何使用该代码的信息。

At a guess, you don't have KeyPreview set to true, or you have a shortcut key assigned to CTRL+E or CTRL+N which is getting precedence.

If that doesn't help, we will need a load more info on exactly how you are using that code.
