C#搞定进度条和其他控件联动

常常为了WINFORM进度条和其他控件联动所烦恼,下面代码将解决这个问题。

 //俩个进程共享数据
        private volatile int d = 1;
        private volatile int bc = 0;

 private void button1_Click(object sender, EventArgs e)
        {
            //Form加载的时候启动一个手工线程. 
            System.Threading.Thread thread = new System.Threading.Thread(new System.Threading.ThreadStart(NumberIncrement));
            thread.Start();
        }

 private void NumberIncrement()
        {//数据执行流程
            int[,] arr = new int[100, 2];
            for (int i = 0; i < 100; i++)
            {
                Random dm = new Random();
                arr[i, 0] = i;
                int sd = dm.Next(1, 10);
                arr[i, 1] = sd;
                d = i;
                bc = sd;
                EventHandler eh = new EventHandler(DisplayNumber);
                this.Invoke(eh, new object[] { null, null });
                Thread.Sleep(sd * 500);
            }
        }

private void DisplayNumber(object sender, EventArgs e)
        {
            //这里给UI控件赋值. 
            label1.Text = "正在执行第" +(d+1).ToString() + "记录,花费时间为" + bc.ToString();
            progressBar1.Value = d;
        }
