如何实现按F5响应button1

Question

如何实现按F5  响应button1 事件???

Answer 1

WINFORM??代码还是 思路？？给个思路吧找到 BTN1的 键盘DOWN事件然后获取 键盘上的按键是F5的时候  委托 执行BTN1的CLICK事件

Answer 2

在KeyPress事件里面判断点击的是否是F5键,是的话执行button1事件

Answer 3

using System;
using System.Collections.Generic;
using System.ComponentModel;
using System.Data;
using System.Drawing;
using System.Text;
using System.Windows.Forms;namespace WindowsApplication18
{
    public partial class Form1 : Form
    {
        public Form1()
        {
            InitializeComponent();
        }        private void button1_Click(object sender, EventArgs e)
        {
            MessageBox.Show("我就是看看按F5行不行");
        }        private void Form1_KeyUp(object sender, KeyEventArgs e)
        {
            //判断是否按下的是F5
            if (e.KeyCode ==Keys.F5)
            {
                //委托 增加BTN的点击事件
                this.KeyUp +=new KeyEventHandler(button1_Click);
                //相应的 去除BTN的点击事件 否则 连续按F5 会增加委托事件
                this.KeyUp -= new KeyEventHandler(button1_Click);
            }
        }        private void Form1_Load(object sender, EventArgs e)
        {
            //Form 是否注册 键盘事件 默认为FALSE
            this.KeyPreview = true;
        }
    }
}

如果项目全局用的话注册热键比较好[DllImport("user32")]
        public static extern bool RegisterHotKey(IntPtr hWnd, int id, uint control, Keys vk);        [DllImport("user32")]
        public static extern bool UnregisterHotKey(IntPtr hWnd, int id);        protected override void WndProc(ref Message m)
        {
            switch (m.Msg)
            {
                case 0x0312:
                    if (m.WParam.ToString() == "123")
                    {
                        this.Hide();
                    }
                    else if (m.WParam.ToString() == "456")
                    {
                        this.Visible = true;
                    }
                    break;
            }
            base.WndProc(ref m);        }        private void BookShelf_Load(object sender, EventArgs e)
        {
            //register:press [H] key to hide,and press [S] key to show
            RegisterHotKey(this.Handle, 123, 0, Keys.H);
            RegisterHotKey(this.Handle, 456, 0, Keys.S);
        }        private void BookShelf_FormClosed(object sender, FormClosedEventArgs e)
        {
            //unregister the hide/show hotkey
            UnregisterHotKey(this.Handle, 123);
            UnregisterHotKey(this.Handle, 456);
        }

用什么建不好,你怎么偏要去用F5,本来WINDOS就响应这个键了,换一个嘛
