C# 多线程操作同一个textbox

Question

        private object sync = new object();        delegate void SetTextCallback(string text);        private void WorkThread()
        {
            this.ReadText();
            this.WorkThread();//为了循环
        }        private void ReadText()
        {
            int a;
            lock(sync)
            {
                a = Convert.ToInt32(textBox1.Text);
            }
            Thread.Sleep(1000);
            a++;
            lock(sync)
            {
                this.SetText(a.ToString());
            }
        }        private void SetText(string text)
        {
            // InvokeRequired required compares the thread ID of the
            // calling thread to the thread ID of the creating thread.
            // If these threads are different, it returns true.
            if (this.textBox1.InvokeRequired)
            {
                SetTextCallback d = new SetTextCallback(SetText);
                this.Invoke(d, new object[] { text });
            }
            else
            {
                this.textBox1.Text = text;
            }
        }
这样一段代码用下面代码创建线程            Thread t = new Thread(new ThreadStart(WorkThread));
            t.Start();
循环指向那段启动代码启动的貌似也只是一个线程.
怎样才能用一个多个线程公用一个 方法?   或者我的代码就不对?

Answer 1

使用线程数组
Thread t[i]=new Thread(new ThreadStart(WorkThread));
t[i].Start();
