c# - 在单独的线程上运行自己的类

Question

我想在另一个线程中运行自己的类，但如果这样做，我就不能在 EventHandler 中使用我的标签，我该如何避免呢？

这就是我的代码的样子:

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 Ts3_Movearound
{
    public partial class Form1 : Form
    {
        TS3_Connector conn = new TS3_Connector();
        Thread workerThread = null;
        public Form1()
        {
            InitializeComponent();
            conn.runningHandle += new EventHandler(started);
            conn.stoppedHandle += new EventHandler(stopped);
        }

        private void button1_Click(object sender, EventArgs e)
        {
            //System.Threading.Thread connw = new System.Threading.Thread(conn);
            workerThread = new Thread(conn.Main);
            workerThread.Start();
        }

        public void started(Object sender, EventArgs e)
        {
            label1.Text = "Status: Running!";
        }
        public void stopped(Object sender, EventArgs e)
        {
            label1.Text = "Status: Stopped!";
        }
    }
}

这就是错误:

InvalidOperationExpetion in Line "label1.Text = "Status: Running!";"

Answer 1

您只能通过 UI 线程更新控件。使用 label1.Invoke() 来做到这一点:

label1.Invoke((MethodInvoker)delegate {
    label1.Text = "Status: Running!";"
});
