多线程执行顺序invoke、Task

代码

 public partial class Form1 : Form
 {
     AutoResetEvent a = new AutoResetEvent(false);//自动复位
     AutoResetEvent b = new AutoResetEvent(false);
     AutoResetEvent c = new AutoResetEvent(false);
     public Form1()
     {
         InitializeComponent();
     }
     private void button1_Click(object sender, EventArgs e)
     {
         a.Set();
         Task.Run(() => A());//开始进程
         Task.Run(() => B());
         Task.Run(() => C());
     }
     private void A()
     {
         while (true)
         {
             a.WaitOne();
             this.Invoke(new Action(() => { this.richTextBox1.Text += "开始-读取PLC\r\n"; }));
             Thread.Sleep(1000);
             this.Invoke(new Action(() => { this.richTextBox1.Text += "完成-读取PLC\r\n"; }));
             Thread.Sleep(1000);
             b.Set();
         }
     }
     private void B()
     {
         while (true)
         {
             b.WaitOne();
             this.Invoke(new Action(() => { this.richTextBox2.Text += "开始-绘制曲线\r\n"; }));
             Thread.Sleep(1000);
             this.Invoke(new Action(() => { this.richTextBox2.Text += "开始-绘制曲线\r\n"; }));
             Thread.Sleep(1000);
             c.Set();

         }
     }

     private void C()
     {
         while (true)
         {
             c.WaitOne();
             this.Invoke(new Action(() => { this.richTextBox3.Text += "开始-保存数据库\r\n"; }));
             Thread.Sleep(1000);
             this.Invoke(new Action(() => { this.richTextBox3.Text += "开始-保存数据库\r\n"; }));
             Thread.Sleep(1000);
             a.Set();
         }
     }
 }

执行效果

Invoke等效分解

Invoke主要用于子线程中对UI页面更新数据

完整Invoke

匿名Invoke
