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()

I believe the best way to solve this should be simple.. You first write code that returns the generic arguments (or argument in your case) of the IEnumerable then write another line to make a comparison of the argument type you desire to compare to the type contained in the IEnumerable object (int, in your case). I have an example that displays two simple functions that handles both tasks.

    public static Type GetEnumerableArgumentType(Type type)
    {
        if (type.IsGenericType && type.GetGenericTypeDefinition() == typeof(IEnumerable<>))
            return type.GetGenericArguments()[0];
        else
            return null;            
    }        

    public static bool EnumerableContainsArgumentType(Type tEnumerable, Type tGenArg)
    {
        return GetEnumerableArgumentType(tEnumerable) == tGenArg;
    }
