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();}));}}}
}
