Datatable implements IEnumerable?

Question

In picture :

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 ?

Answer 1

You're looking at the wrong AsEnumerable method - you're calling DataTableExtensions.AsEnumerable . rather than Enumerable.AsEnumerable .

Answer 2

对于使用dotnet core并存在相同问题的任何人，您都需要在Nuget中添加“ System.Data.DataTableExtensions”
