Anyone knows how to get the Obsolete attribute when using Linq?
I'm doing NDepend but anyways I want to make a query and get all the obsolete attributes from the methods that are supposed to be "deprecated"
Obsolete["I WANT THIS STRING"]

In LINQ/C# per reflection or CINQ/NDepend? – Matten Jul 05 '13 at 11:04

I believe something like this is what you are looking for
from type in YourAssembly
from p in type.GetProperties()
from m in type.GetMembers()
let propertyAttributes = p.GetCustomAttributes(true)
let methodAttributes = m.GetCustomAttributes(true)
where propertyAttributes.Any(a => a.GetType() == typeof(ObsoleteAttribute))
|| methodAttributes.Any(a => a.GetType() == typeof(ObsoleteAttribute))
select new type;
It queries all types in an assembly and selects those which have properties or methods with the ObsoleteAttribute.
