PostSharp

[ThomasS]

First of all I have to say I just started exploring PostSharp. I have looked into Sprint.Net and Castle Windsor before. But in general, I'm relative new to AOP.

What I would like to do with PostSharp is automatically creating asynchronous methods and event handlers for non-void methods.

Suppose you have an Interface IOrderService. And a few classes that implement that interface. I want to inject code into these classes so they have asynchronous method calls and event handlers to handle return values.

For example:

Code: Select all

public interface IOrderService
{
   void CreateOrder(order);
}

public class OrderWebService : WebService, IOrderService
{
    public void CreateOrder(order){
          //Calling the CreateOrderWebMethod
          base.Invoke(....);
   }
}

This class should then, after postsharp compilation, have the following extra methods:

public class OrderWebService : WebService, IOrderService
{
     public void CreateOrder(order){
          //Calling the CreateOrderWebMethod
          base.Invoke(....);
    }

     //generated method
     public void CreateOrderAsync(order){
          //Calling the CreateOrderWebMethod
         base.InvokeAsync(.....)
    }
   
     public event CreateOrderCompleted OnCreateOrderCompleted;
}


I don't know if this is possible with postsharp. It won't surprise me if it is. But i don't find any amples that create extra code. Can you give me any keywords, push in the right direction,..?

Many thanks in advance

You could do it using PostSharp Core, but I wonder if it would not be better to use partial classes and a classic code generator.
