响应键盘的“咚咚”声音去掉

在按键处理的代码里填上 e.Handled = true; 就没声音了

 

 private void textBoxCodebar_KeyPress(object sender, KeyPressEventArgs e)
        {
            if (e.KeyChar == Convert.ToChar(Keys.Enter))
            {
   
                button2_Click(sender, e);
                e.Handled = true;
            }
        }
