也写个异步调用

 
 
今天第一次用live Writer写代码，先发一个！ 异步代码。
 
 
 
 
 
 
 
 
 
using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Threading;
 
 
namespace Asyncalback
{
 
     
    public   delegate string deleDoing(string argsInput);
 
    class AsyncalCall
    {
 
  private static  deleDoing deleDoingObj = new deleDoing(SaySomeThingsNeedLitterOfTime); // 三部曲，定义委托，二 定义方法执行（主要是begininvoke，和endinvoke），和，三是返回结果存放位置
      private static string SomeThingsNeedLitterOfTimeResult = string.Empty; //返回结果的变量
  public static void Main()
        {
             Console.WriteLine("开始工作。。。");
             string inWorkinArges = "参数"; //费事的工作传入参数
 
            deleDoingObj.BeginInvoke(inWorkinArges, new AsyncCallback(TaskFinished), null); //执行
 
            doAnotherThinges();
 
            Console.ReadLine();
 
 
 
        }
 
 
 
 
        /// <summary>
        /// 模拟其它执行过程
        /// </summary>
        private static  void   doAnotherThinges()
        {
 
 
            for (int i = 0; i < 10; i++)
            {
 
                Console.WriteLine(i);
 
                Console.WriteLine("其它程序"+System.DateTime.Now.ToString());
            
 
                Thread.Sleep(100);
                Console.WriteLine("其它程序"+System.DateTime.Now.ToString());
            }
 
 
        }
 
 
 
        /// <summary>
        /// 返回的结果费时的结果 执行的情况
        /// </summary>
        /// <param name="result"></param>
        public static void TaskFinished(IAsyncResult result)
        {
            Console.WriteLine("执行结果回调一次"+System.DateTime.Now.ToString());
             SomeThingsNeedLitterOfTimeResult = deleDoingObj.EndInvoke(result);
             Console.WriteLine("执行结果回结束"+System.DateTime.Now.ToString());
             Console.WriteLine("执行结果是:SomeThingsNeedLitterOfTimeResult" + SomeThingsNeedLitterOfTimeResult);
 
        }
 
     
 
 
        private static string SaySomeThingsNeedLitterOfTime(string argsInput)
        {
 
            string reture = string.Empty;
            int cout=0;
            for (int i = 0; i < 10; i++)
            {
 
               
 
                Console.WriteLine("执行费时程序"+System.DateTime.Now.ToString());
                Thread.Sleep(100);
                Console.WriteLine("执行费时程序"+System.DateTime.Now.ToString());
                cout+=i;
 
            }
 
            reture = cout.ToString();
            return reture;
        
        
        }
    }
}
