我需要表单添加alt+1键来打开表单3,但由于某种原因,当我调试并按下快捷键时,它没有打开快捷键
下面是表单2
中的代码段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,如果它有帮助,它不会像预期的那样打开形式3,这里是我在形式2中使用的整个代码:(更新)(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
