a kind of async programming in c#, need to reference definition

void Main()

{

	Run d=new Run(RunHandler);

	IAsyncResult result= d.BeginInvoke(new AsyncCallback(CallBack),new string[]{"sdf","sdffd"});

	IAsyncResult res=d.BeginInvoke(r=>{},"");

	//i.e. asyncresult is a wrapperclass that wraps the state

	d.EndInvoke(d.BeginInvoke(re=>{Console.WriteLine (re.AsyncState);},"async state"));

	d.EndInvoke(result);

	Console.WriteLine (3);

}

void RunHandler(){

Console.WriteLine (1);

}

void CallBack(IAsyncResult result){

Console.WriteLine (result.AsyncState);

Console.WriteLine (2);}

// Define other methods and classes here

public delegate void Run();

result showed like:

1

1

5String[] (2 items)4

sdf

sdffd 

2

1

3

void Main()

{

	Console.WriteLine (Geta().Result);

}

// Define other methods and classes here

 async Task<String> Get(){

return "aa";

}

async Task<string> Geta(){

var a=await Get();

return "bb"+a;

}
