Handling Exception using C# Attribute

Question

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?

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
