How does AsEnumerable Methods Knows that the type should be DataRow ?

I’ve searched in Reflector and Datatable does Not implement IEnumerable..

And the AsEnumerable code is:

public static IEnumerable<TSource> AsEnumerable<TSource>(this IEnumerable<TSource> source)
{
    return source;
}

What am I missing ?

You’re looking at the wrong AsEnumerable method – you’re calling DataTableExtensions.AsEnumerable. rather than Enumerable.AsEnumerable.
