c# - Does Entity Framework 4 have a Contains feature? -

I am currently using an extension of Linux so that I can get the functionality of this. Where do I call it:

  answer = answer Where in (x => x.category.catid, Catastrar);  

What's built in a function within the entity framework to use?

pseudo code

  answer. Where (x = & gt; catSTRarray.Contains (x.category.catid));
