Finding out if a type implements a generic interface

Question

Let\'s say I have a type, MyType. I want to do the following:

1. Find out if MyType implements the IList interface, for some T.
2. If the answer to (1) is y

Answer 1

If i understand your question correctly, this is what you are trying to do. If not, please explain further.

public class MyType : ISomeInterface
{
}

MyType o = new MyType();

if(o is ISomeInterface)
 {
 }

edit: if you change your question, please add the fact that you edited..because now my answer looks like it doesn't belong.

In that case, here is a very large LINQ

            var item = typeof(MyType).GetInterfaces()
                            .Where(x => x.IsGenericType && x.GetGenericTypeDefinition() == typeof(IList<>))
                            .Select(t => t.GetGenericArguments().First())
                            .FirstOrDefault();

if( item != null )
 //it has a type
