Button.PerformClick()

Button.PerformClick()

Button.PerformClick()和button.click()事件是

1、button.PerformClick()和button_Click(sender,e)的功能：

   两者都是实现单击button控件功能。

2、两者存在的一点小差异

实例：

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 SuperPlane
{
    public partial class Form1 : Form
    {
        public Form1()
        {
            InitializeComponent();
        }
        private void button1_Click(object sender, EventArgs e)
        {
            MessageBox.Show("button1");//弹出窗口
        }
        private void button2_Click(object sender, EventArgs e)
        {
            //无论button1.Enabled为true还是为false都会弹出窗口
            button1_Click(sender, e);//以button.Click(sender,e)调用button1.Click方法
        }
        private void button3_Click(object sender, EventArgs e)
        {
            //只有当button1.Enabled为true时才会弹出窗口
            button1.PerformClick();//以button1.PerformClick()模拟button1单击事件
        }
        private void button4_Click(object sender, EventArgs e)
        {
            button1.Enabled = !button1.Enabled;//改变button1的Enabled改变
        }
    }
}
