Processing Exception Using C # Attribute

Question

I thought it was possible to handle exceptions using an attribute rather than writing "try ... catch" in each individual method.

For example, now each of my methods looks like this:

public void DoSomething() { try { // do something } catch (Exception ex) { // exception handling rules, always the same. throw; } } 

I want to:

 [HandleException] public void DoSomething() { // do something } 

Is it possible?

Answer 1

This can be done using AOP (aspect-oriented programming). One framework for this is PostSharp. See Sample http://www.sharpcrafters.com/solutions/exception

Alternatively, you can write your own MSBuild task. Here you can find an open source project. At compile time, it introduces INotifyPropertyChanged supporting code in the property setting tools using the Mono.Cecil lib.
