.NET : Get property name in attribute

Question

[MyAttribute()]
public string Name { get; set; }

In MyAttribute I need to know the name of associated property, is it possible?

EDIT:

I need to use it in text formatting.

Can you elaborate on why you need it and what you would use it for? — Lasse V. Karlsen, May 09 '10 at 11:07

No, this is not possible. Usually you would use reflection to read attributes applied on a given property, so you already know the property. Example:

var properties = typeof(SomeType).GetProperties();
foreach (var property in properties)
{
    var attributes = property.GetCustomAttributes(typeof(MyAttribute), true);
    if (attributes.Count > 0)
    {
        // look at property.Name here
    }
}

Yes, you start by a type, then get the properties and finally read the custom attributes applied to a given property. – Darin Dimitrov May 09 '10 at 11:19

You can use a PostSharp aspect to do the job. I had a similar question a while back, which was almost the same thing. You can see comments on the answer for more info about some of the implications that you might encounter.
