Attribute which wraps functionality of its decorated function within some outer code

Question

Possible Duplicate:
C# wrap method via attributes

I'd like to achieve such functionality:

[Wrap]
public void Foo()
{           
    /* foo logic */
}

Where [Wrap] attribute is an attribute, which wraps function logic within some outer code - just for example let it be a transaction scope:

using(var scope = new TransactionScope())
{
    /* foo logic */
    scope.Complete();
}

How to write such an attribute ?

That's an example of aspect oriented programming where Wrap is an aspect.

C# has no built in support for aspect oriented programming, but there are addons such as postsharp that supports it.
