识别KeyDown中的菜单键

Question

当用户在文本框中推送this button时，我想做点什么。这就是我试过的：

private void txtInvisible_KeyDown(object sender, KeyEventArgs e)
{
    if (e.KeyCode == Keys.Menu)
    {
        MessageBox.Show("the context menu key was pressed");
    }
}

我尝试过Keys.L，并触发了它。也许Keys.Menu可能是错误的键？

Answer 1

应为Keys.Apps。

Answer 2

如前所述。 keys.Apps就是你要找的。 Here您可以找到所有密钥

Answer 3

只需使用Keys.Apps键。

private void txtInvisible_KeyDown(object sender, KeyEventArgs e)
{
    if(e.KeyCode == Keys.Apps)
    {
        MessageBox.Show("the context menu key was pressed");
    }  
}
