检测回车键C＃ [英] Detect Enter Key C#

问题描述

我有下面的代码输入/被压回时不显示消息框。

I have the following code which does not show the MessageBox when enter/return is pressed.

有关任何其他键（即字母/数字）的消息框显示的是假

For any other key(i.e. letters/numbers) the MessageBox shows False.

private void cbServer_TextChanged(object sender, EventArgs e)
{
    if (enterPressed)
    {
        MessageBox.Show("Enter pressed");
    }
    else
        MessageBox.Show("False");
}

private void cbServer_Keydown(object sender, KeyEventArgs e)
{
    if (e.KeyCode == Keys.Enter || e.KeyCode == Keys.Return)
    {
        enterPressed = true;
        MessageBox.Show("Enter presssed: " + enterPressed);

    }
    else
        enterPressed = false;
}

任何想法？

Any ideas?

编辑：上面的代码，我认为这个问题是与_Keydown即便如此，我只贴了

Above code, I thought the issue was with the _Keydown even so I only posted that.

推荐答案

这是因为当您按下<大骨节病>输入 框TextChanged 事件将不会触发。

This is because when you press Enter TextChanged event won't fire.
