Does Entity Framework 4 have a Contain function?

Question

I am now using the linq extension to provide me with Contains functionality. I call WhereIn as follows:

Answers = Answers.WhereIn(x => x.category.catid, catSTRarray); 

Is there a built-in function in the entity structure to use?

Answer 1

pseudo code

 Answers.Where(x => catSTRarray.Contains(x.category.catid));
