.NET并行计算和并发3.2-多线程调用Invoke

  1  public partial class Form1 : Form
  2     {
  3         private delegate  void mydelegate(long j);
  4         private mydelegate  dele;
  5         public Form1()
  6         {
  7             InitializeComponent();
  8             dele += new mydelegate(delegateMethod);
  9         }
 10 
 11         private void delegateMethod(long j)
 12         {
 13             this.textBox1.Text = j.ToString();
 14         }
 15 
 16         private void button1_Click(object sender, EventArgs e)
 17         {
 18             Thread thd = new Thread(threadMethod);
 19             thd.Start();
 20         }
 21 
 22         private void threadMethod()
 23         {
 24             long j = 0;
 25             for (int i = 0; i < 1e10; i++)
 26             {
 27                 j++;
 28                 if (j%1000 == 0)
 29                 {
 30                     //调用Invoke方法后，会在原来的创建textbox1的线程中执行delegateMethod方法。
 31                     this.Invoke(dele,j);
 32                 }
 33             }
 34         }
