1、设置窗体KeyPreview属性为True
2、添加窗体的KeyDown事件
/// <summary> /// 窗体的keydown事件响应 添加快捷键 /// </summary> /// <param name="sender"></param> /// <param name="e"></param> private void frmScan_KeyDown(object sender, KeyEventArgs e) { if (e.KeyCode == Keys.Space) { MessageBox.Show("空格键"); } if (e.KeyCode == Keys.Enter) { MessageBox.Show("回车键"); }
}
