yunfeng83 2021-08-13 原文

public class ThreadInvoker
    {
        /// <summary>
        /// 回调委托 带参数的
        /// </summary>
        /// <param name="InvokerClass"></param>
        public delegate void CallbackFunc(InvokerClass InvokerClass);
        /// <summary>
        /// 回调委托的方法
        /// </summary>
        public CallbackFunc AsynCallback;
        /// <summary>
        /// 线程
        /// </summary>
        public Thread thread;
        /// <summary>
        /// 执行循环停止属性
        /// </summary>
        public bool Stop = false;
        /// <summary>
        /// 休眠间隔
        /// </summary>
        public int Sleep = 1000;
        public ThreadInvoker(CallbackFunc callback)
        {
            AsynCallback = callback;
        }
        public virtual void Start(ThreadStart ThreadStart)
        {
            thread = new Thread(ThreadStart);
            thread.Start();
        }

        public virtual void Start(ParameterizedThreadStart ThreadStart)
        {
            thread = new Thread(ThreadStart);
            thread.Start();
        }
    }

public class InvokerClass
    {
        public string String { get; set; }

    }

使用方法

 public partial class Form1 : Form
    {
        public Form1()
        {
            InitializeComponent();
        }
        ThreadInvoker ti;

        private void Form1_Load(object sender, EventArgs e)
        {

        }

        public void Excete(object InvokerClass)
        {
            InvokerClass _InvokerClass = InvokerClass as InvokerClass;
            while (!ti.Stop)
            {
                if (null == _InvokerClass)
                    _InvokerClass = new InvokerClass();

                _InvokerClass.String = DateTime.Now.ToString("yyyy-MM-dd HH:mm:ss");
                ti.AsynCallback(_InvokerClass);
                Thread.Sleep(ti.Sleep);
            }
        }

        public void AsynUpdateTxtMethod(InvokerClass InvokerClass)
        {
            if (this.richTextBox1.InvokeRequired)
            {
                this.BeginInvoke(new ThreadInvoker.CallbackFunc(updatemethod), InvokerClass);
            }
            else
            {
                updatemethod(InvokerClass);
            }
        }

        public void updatemethod(InvokerClass InvokerClass)
        {
            this.richTextBox1.AppendText(InvokerClass.String + "\r\n");
            this.richTextBox1.ScrollToCaret();
        }

        /// <summary>
        /// 启动
        /// </summary>
        /// <param name="sender"></param>
        /// <param name="e"></param>
        private void button1_Click(object sender, EventArgs e)
        {
            ti = new ThreadInvoker(AsynUpdateTxtMethod);
            ti.Stop = false;
            ti.Start(new System.Threading.ParameterizedThreadStart(Excete));
        }

        private void button2_Click(object sender, EventArgs e)
        {
            ti.Stop = true;
        }
    }
