In condition using LINQ

Question

OK, another LINQ question. How do I do an \"IN\" condition using LINQ. I have an IEnumerable list of myObject and want to do something like myObject.Description in(\'Help\',

Answer 1

Use Contains on a collection:

string[] descriptions = { "Help", "Admin", "Docs" };

var query = from foo in list
            where descriptions.Contains(foo.Description)
            select ...;

(For larger collections, a HashSet might be better.)
