键盘快捷方式无法按预期打开表单3

Question

我需要表单添加键alt + 1打开表单3但是由于某种原因我调试并按下快捷键时它不会打开快捷方式

以下是表单2的代码段

private void Form1_KeyDown(object sender, KeyEventArgs e)
{
    if (e.Alt && e.KeyCode == Keys.A)
    {
        Form3 f3 = new Form3();
        f3.ShowDialog();
    }

}

正如我所说，如果ti有帮助，它不会打开表格3，这是我在表单2中使用的整个代码： [更新] [未解决]

using System;
using System.Collections.Generic;
using System.ComponentModel;
using System.Data;
using System.Drawing;
using System.Linq;
using System.Text;
using System.Windows.Forms;

namespace WindowsFormsApplication1
{
    public partial class Form2 : Form
    {
        public Form2()
        {
            InitializeComponent();
            this.KeyPreview = true;
            this.KeyDown += new KeyEventHandler(Form1_KeyDown);

        }

        private void pictureBox1_Click(object sender, EventArgs e)
        {
            var myForm = new Form2();
            myForm.Show();

        }
        private void Form1_KeyDown(object sender, KeyEventArgs e)
        {
            if (e.Alt && e.KeyCode == Keys.A)
            {
                Form3 f3 = new Form3();
                f3.ShowDialog();
            }

        }

        private void Form2_Load(object sender, EventArgs e)
        {

        }
    }
}

您需要将表单的KeyPreview属性设置为True。
