一个C#实现异步调用的简单范例源码

把做工程过程常用的代码段备份一下，下边代码是关于一个C#实现异步调用的简单范例的代码。

using System;
using System.Threading;
using System.Runtime.Remoting.Messaging;

namespace Test
{
class Program
{
public delegate int BinaryOp(int x,int y);
public static void Main(string[] args)
{
Console.WriteLine(“Main() invoked on thread{0}”,Thread.CurrentThread.ManagedThreadId);
BinaryOp b = new Program.BinaryOp(Add);
IAsyncResult iftAR = b.BeginInvoke(10,10,new AsyncCallback(AddComplete),null);
Console.WriteLine(“不等它，咱继续！”);
Console.ReadKey();

    }
    static void AddComplete(IAsyncResult itfAR)
    {
        Console.WriteLine("Addcomplete invoked on thread{0}",Thread.CurrentThread.ManagedThreadId);
        Console.WriteLine("your addtion is complete");
        AsyncResult ar = (AsyncResult)itfAR;
        BinaryOp b = (BinaryOp)ar.AsyncDelegate;
        Console.WriteLine("10+10={0}",b.EndInvoke(itfAR));
        
    }
    static int Add(int x,int y)
    {
        Console.WriteLine("Add () invoked on thread{0}",Thread.CurrentThread.ManagedThreadId);
        Thread.Sleep(5000);
        return x+y;
    }
}

}
