Determine if collection is of type IEnumerable

Question

How to determine if object is of type IEnumerable ?

Code:

namespace NS {
    class Program {
        static IEnumerable GetInts()         


        

Answer 1

i is of type NS.1.Program+d__0, which is a subtype of IEnumerable. Thus, you can use either

if (i is IEnumerable) { ... }

or IsAssignableFrom (like in Marc's answer).
