How to use GroupBy using Dynamic LINQ

Question

I am trying to do a GroupBy using Dynamic LINQ but have trouble getting it to work.

This is some sample code illustrating the problem:

List

        

Answer 1

This is the method I have copied from DynamicQuery:

public static IQueryable GroupBy(this IQueryable source, string keySelector, string elementSelector, params object[] values) {..}

In my example I provide the keySelector and the elementSelector.

listAlbums.AsQueryable().GroupBy("it.Shop", "it").Select("Author"); You can use new with GroupBy or with select for the new types.

It like this in OOP class.
