C# 委托 / 跨线程访问UI / 线程间操作无效: 从不是创建控件“Form1”的线程访问它
网上的代码都比较复杂,还是这个简单
见代码,
简易解决办法:
主窗体代码
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.Threading; using System.Windows.Forms; namespace WindowsFormsApp1 { public partial class Form1 : Form { public Form1() { InitializeComponent(); } private void button1_Click(object sender, EventArgs e) { Thread func = new Thread(lib.test_func); func.Start(this); } } }
线程代码:
using System; using System.Collections.Generic; using System.Linq; using System.Text; using System.Threading.Tasks; namespace WindowsFormsApp1 { public static class lib { public static void test_func(object frm) { var frm2 = frm as Form1; while (true) { System.Threading.Thread.Sleep(100); frm2.Invoke(new Action(() => { frm2.Text = DateTime.Now.ToString(); })); } } } }
