带有Ctrl键的KeyPressEventArgs.KeyChar的值 [英] Value of KeyPressEventArgs.KeyChar with ctrl key

问题描述

在KeyPressEvent上，我知道如何检测 CTRL 键何时按下，但是随后我想获取 CTRL + [什么?].

On a KeyPressEvent I know how to detect when the CTRL key is down, but then I want to get CTRL+[what?].

使用 CTRL + A 时，KeyChar = 1， CTRL + B 给出2，依此类推.检测 CTRL + a 输入的最佳方法是什么?

With CTRL+A, KeyChar = 1, CTRL+B gives 2, etc. What is the best way to detect CTRL+a input?

这是我的代码:

private void textBox1_KeyPress(object sender, KeyPressEventArgs e)
{
    if (ModifierKeys.HasFlag(Keys.Control))
    {
        Console.Write("(Ctrl) ");
    }
    Console.WriteLine(Convert.ToString(Convert.ToInt32(e.KeyChar)));
}

输入 a ， b ， CTRL + a ， CTRL + b 给出:

Entering a, b, CTRL+a, CTRL+b gives:

97
98
(Ctrl) 1
(Ctrl) 2

推荐答案

我的建议是使用

My suggestion is to use KeyDown event rather then KeyPress, because KeyPress works with processed input. KeyDown works with "raw" data (not quite, but enough for your purpose). KeyDown event handler has a parameter which holds data you need: KeyEventArgs
