多線程顯示運作狀态

最近碰見一個例子，Copy大檔案或者網絡通路的時候處理假死。 那就用多線程加個進度條(隻顯示運作，沒有進度)來表示狀态運作吧。好了，廢話少說，上個例子。先看結果圖：

程式說明：

點選Button，運作一個資料累加器，textBox顯示每次運作的結果，ProgressBar表示運作的狀态。

好了，直接貼代碼：

namespace Testpro
{
    public partial class Form1 : Form
    {
        BackgroundWorker work = new BackgroundWorker();
        public Form1()
        {
            InitializeComponent();
            work.WorkerReportsProgress = true;
            work.DoWork += Count;
            work.RunWorkerCompleted += completeRun;
            Control.CheckForIllegalCrossThreadCalls = false;
            this.textBox1.ScrollBars = ScrollBars.Both;
        }

        private void button1_Click(object sender, EventArgs e)
        {
            this.progressBar1.Style = ProgressBarStyle.Marquee;
            
            work.RunWorkerAsync();
        }

        private void Count(object sender, DoWorkEventArgs e)
        {            
            float num = 0.0f;
            int cun = 0;
            while (num < 5000)
            {
                cun++;
                num += 4f;              
               this.textBox1.Text += num.ToString() + "\t" + e.Result;
               if (cun == 9)
               {
                   textBox1.Text += Environment.NewLine;
                   cun = 0;
               }
            }            
        }

        public  void SetText(object num)
        {
            textBox1.Text += num.ToString() + "\n";
        }

        private void completeRun(object sender,  RunWorkerCompletedEventArgs e)
        {
            this.progressBar1.Style = ProgressBarStyle.Blocks;
            
            this.textBox1.Text += "complete";
            MessageBox.Show("Running complete.....");
        }       
    }
}
