LINQ to Entities - Where IN clause in query

Answer 1

Use Contains:

int[] ids = { 1, 2, 3, 4, 5};

var query = db.myTable.Where(item => ids.Contains(item.ID));

or in query syntax:

int[] ids = { 1, 2, 3, 4, 5};

var query = from item in db.myTable
            where ids.Contains(item.ID)
            select item;

Answer 2

I think answer lies somewhere along these lines...

Array a = {1,2,3,4,5}

...WHERE a.Contains(ID)
