1. 使用MethodInvoker

using System;
using System.Collections.Generic;
using System.ComponentModel;
using System.Data;
using System.Drawing;
using System.Linq;
using System.Text;
using System.Threading;
using System.Threading.Tasks;
using System.Windows.Forms;
namespace InvokeTest
{
public partial class Form1 : Form
{
    public static int x = 0;
    public Form1()
    {
        InitializeComponent();
        Thread thread = new Thread(new ThreadStart(ThreadProc));
        thread.IsBackground = true;
        thread.Start();
    }
    public void changeLable()
    {
        x++;
        label1.Text = Convert.ToString(x);
    }
    public void ThreadProc()
    {
        MethodInvoker send = new MethodInvoker(changeLable);            
        while (true)
        {
            Thread.Sleep(1000);
            BeginInvoke(send);
        }
    }
}
}

2. 使用EventHandler

using System;
using System.Collections.Generic;
using System.ComponentModel;
using System.Data;
using System.Drawing;
using System.Linq;
using System.Text;
using System.Threading;
using System.Threading.Tasks;
using System.Windows.Forms;

namespace InvokeTest
{
public partial class Form1 : Form
{
    public static int x = 0;

    public Form1()
    {
        InitializeComponent();
        Thread thread = new Thread(new ThreadStart(ThreadProc));
        thread.IsBackground = true;
        thread.Start();
    }

    public void ThreadProc()
    {
        EventHandler send = new EventHandler(label1_Click);
        
        while (true)
        {
            Thread.Sleep(1000);
            BeginInvoke(send);
        }
    }

    private void label1_Click(object sender, EventArgs e)
    {
        x++;
        label1.Text = Convert.ToString(x);
    }
}
}
