推荐答案

我不明白这个的目的。但是，有可能这样做。



请按照步骤，



步骤1）

您需要在表单级别处理Keypress事件。见下面的代码

I don't understand the purpose of this. However, it is possible to do so.

Please follow the steps,

Step 1)
You will need to handle the Keypress event in form level. See below code

public partial class Form1 : Form
    {

        private bool YKeyEntered = false;

        public Form1()
        {
            InitializeComponent();
        }

        private void Form1_KeyPress(object sender, KeyPressEventArgs e)
        {
            if (YKeyEntered)
            {
                chkInternal.Checked = true;
            }
        }

        private void Form1_KeyDown(object sender, KeyEventArgs e)
        {
            if (e.KeyCode == Keys.Y)
            {
                YKeyEntered = true;
            }
        }
    }

第2步

默认情况下，表单无法读取密钥。将表单的KeyPreview属性设置为true，以便表单在到达表单上的任何控件之前接收键盘消息。



在此代码，如果在表单处于活动状态时按下键'Y'，则会检查名为'chkInternal'的chechbox。

Step 2
By default Form cannot read a key. Set the 'KeyPreview' property of the form to 'true', so that keyboard messages are received by the form before they reach any controls on the form.

In this code, If the Key 'Y' is pressed when the form is active, the chechbox named 'chkInternal' get checked.
