audio - C#避免在按下KeyDown时发出哔哔声？

Question

在按文本框中的Enter键时，删除哔声时出现问题。

这不起作用:

private void textBox3_KeyDown(object sender, KeyEventArgs e)
    {

        if (e.KeyCode == Keys.Enter)
        {
            e.SuppressKeyPress = true;
            button1.PerformClick();               
        }

    }

我找到了答案!

 private void textBox2_KeyDown(object sender, KeyEventArgs e)
        {
            //Pressing ENTER
            if (e.KeyCode == Keys.Enter)
            {
                button1.Select();
                e.SuppressKeyPress = true;
                SendKeys.Send("{ENTER}");            
            }

        }
