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.

+1. But the phrase "Usually you would use" needs to be: "You have to use".

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.
