从字符串获取事件方法 [英] get event method from string

问题描述

伙计们
我想为这样的事件添加现有的方法

hi guys
i want to add exsiting method for some event like this

string str = "button2_Click";
button2.Click += new EventHandler(str);

假设这堂课

assume this class

public partial class Form1 : Form
    {
        public Form1()
        {
            InitializeComponent();
           // button2.Click += new EventHandler(button2_Click);
        }

        private void button1_Click(object sender, EventArgs e)
        {
            string str = "button2_Click";

            button2.Click += new EventHandler(str);
        } 
        
        void button2_Click(object sender, EventArgs e)
        {
            MessageBox.Show("Done");
        }
    }

如何将字符串"str"转换为EventHandler接受作为事件委托名称的参数.

how to convert string ''str'' to parmeter that EventHandler accept that as Event Delegate name.

推荐答案

感谢所有！

thanks all!

private void button1_Click(object sender, EventArgs e)
        {
            string str = "button2_Click";

            Delegate temp = Delegate.CreateDelegate(typeof(EventHandler),this,str);

            button2.Click += (EventHandler)temp;
        }
