事件委托例子(可跨窗口操作)

事件委托例子:

using System;
using System.Drawing;
using System.Windows.Forms;

namespace 跨窗体调用控件
{
    public partial class Form1 : Form
    {
        public Form1()
        {
            InitializeComponent();
        }
        private void button1_Click(object sender, EventArgs e)
        {
            Form2 f = new Form2();
            f.ChangeColor += new ChangeFormColor(f_ChangeColor);
            f.Show();
        }
        void f_ChangeColor(bool topmost)
        {
            this.BackColor = Color.LightBlue;
            this.Text = "改变成功";
        }
    }
}

using System;
using System.Windows.Forms;  

namespace 跨窗体调用控件
{
    public delegate void ChangeFormColor(bool topmost);
    public partial class Form2 : Form
    {
        public Form2()
        {
            InitializeComponent();
        }
        public event ChangeFormColor ChangeColor;
        private void button1_Click(object sender, EventArgs e)
        {
            ChangeColor(true);//执行委托实例
        }
    }
}
