c#异步入门

能用异步,就不要用线程,感觉线程要是控制不好,比较容易出问题

 1        //要异步完成的方法
 2        private void AddRadNum()
 3        {
 4            while(true)
 5            {
 6                Random r = new Random();
 7                lstNum.Items.Add( r.Next(100,1000));
 8                Thread.Sleep(500);
 9            }
10        }
11
12        //定义一个委托
13        private delegate void delegateAddRadNum();
14
15        private void btnOK_Click(object sender, System.EventArgs e)
16        {
17            //实例化委托
18            delegateAddRadNum da = new delegateAddRadNum(AddRadNum);
19            //开始异步
20            IAsyncResult iar = da.BeginInvoke(null, null);
21        }
