• 在Winform 窗体之间 委托事件传值


    Form1
    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 winformDelegate
    {
        public partial class Form1 : Form
        {
            public Form1()
            {
                InitializeComponent();
            }
    
            private void button1_Click(object sender, EventArgs e)
            {
               Form2 frm=new Form2();
               frm.Myevent += GetValue;
                frm.Show();
            }
    
            public void GetValue(string text)
            {
                textBox1.Text = text;
            }
        }
    }
    Form2
    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 winformDelegate
    {
        public partial class Form2 : Form
        {
            public delegate void DelegaeValue
                (string text);
    
            public event DelegaeValue Myevent;
    
            protected virtual void ValueInformation(string text)
            {
                DelegaeValue handler = Myevent;
                if (handler != null)
                    handler(text);
            }
    
            public Form2()
            {
                InitializeComponent();
            }
    
            private void button1_Click(object sender, EventArgs e)
            {
                if (Myevent != null)
                {
                }
                ValueInformation(textBox1.Text);
            }
