Handling Exception using C# Attribute

I was thinking that is it possible to do exception handling using Attribute, rather than write "try...catch" in every single method.

for example, now, each of my method look like this:

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

I want:

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

Is it possible?

You can do this with Fody

https://github.com/Fody/Fody

There is a similar plugin to handle exceptions on async code if you want to check it.

https://github.com/Fody/AsyncErrorHandler

And here is one tutorial.

Also, you can write your own MSBuild Task. Here you can find an opensource project. During compile time it injects INotifyPropertyChanged supporting code in property setters using Mono.Cecil lib.

This can be done via AOP (aspect oriented programming). One of the frameworks for doing so is PostSharp. See a sample http://www.sharpcrafters.com/solutions/exception
