Question

What is the best way to express a LINQ query where the query result only contains keys (of type guid) that are contained in a c# List?

In TSQL it would be something like this.

SELECT * FROM MyView WHERE Keys IN (<guid1>,<guid2>,<guid3>)

Answer 1

from row in db.MyView
where yourList.Contains(row.ID)
select row

Assuming yourList is a List<Guid> (certain collections cause an exception saying that “there is no supported translation to SQL”, try it and if you get that error, make sure you have a List)
