好的,我希望这样做,因此可以单击按钮的数量有限制,因为打开多个框会导致我的应用程序崩溃〜:(
这是我希望阻止它向许多人打开的表单的代码,不要误会我的意思,我确实想要多个盒子,只是不多:
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)
{
}
}
}
