利用委托进行窗体传值
Form1.cs代码:
using System; using System.Collections.Generic; using System.ComponentModel; using System.Data; using System.Drawing; using System.Linq; using System.Text; using System.Threading.Tasks; using System.Windows.Forms; namespace 窗体间传值 { public partial class Form1 : Form { public Form1() { InitializeComponent(); } private void button1_Click(object sender, EventArgs e) { Form2 frm2 = new Form2(ShowMsg); frm2.Show(); } void ShowMsg(string str) { label1.Text = str; } } }
Form2.cs代码:
using System;
using System.Collections.Generic;
using System.ComponentModel;
using System.Data;
using System.Drawing;
using System.Linq;
using System.Text;
using System.Threading.Tasks;
using System.Windows.Forms;
namespace 窗体间传值
{
public delegate void DelTest(string str);//声明一个委托
public partial class Form2 : Form
{
public DelTest _del;
public Form2(DelTest del)
{
this._del = del;
InitializeComponent();
}
private void button1_Click(object sender, EventArgs e)
{
_del(textBox1.Text);
}
}
}
