I have a currently executing assembly with 3 types, they are all

find all of my Types in the current Assembly that have the attribute,
and then put a New instance of each type in a List?

C# 3:

Type[] result = Assembly.GetExecutingAssembly().GetTypes()
.Where(t=>t.IsDefined(typeof(MyAttibute), false)
.Select(t=>Activator.CreateInstance(t));

The result type is wrong there, but hey, who's counting :)

I prefer it as a query expression though:

var result = from type in Assembly.GetExecutingAssembly().GetTypes()
where type.IsDefined(typeof(MyAttribute), false)
select Activator.CreateInstance(type);

List<object> objects = result.ToList();
