Question

What is the LINQ Equivalent of

Select DISTINCT A, B, C from TESTDB WHERE ALPHA =1

I am trying something like this:

var data = TESTDB.WHERE(i=>i.ALPHA==1).SELECT(A,B,C).DISTINCT();

Answer 1

Using anonymous objects will do the trick:

var data = TESTDB.Where(i => i.ALPHA == 1).Select(i => new {i.A, i.B, i.C}).Distinct();

To retain the model:

List<Book> books = db.Book.Select(i => new Book {Author = i.Author, Title = i.Title}).Distinct().ToList();
