I have searched for this, but still can't seem to get this to work for me. I have an array of Id's associated with a user (their Organization Id). These are placed in an int[] as follows:

int[] OrgIds = (from oh in this.Database.OrganizationsHierarchies
                       join o in this.Database.Organizations on oh.OrganizationsId equals o.Id
                       where (oh.Hierarchy.Contains(@OrgId))
                          || (oh.OrganizationsId == Id)
                       select o.Id).ToArray();

The code there isn't very important, but it shows that I am getting an integer array from a Linq query.

From this, though, I want to run another Linq query that gets a list of Personnel, that code is as follows:

List<Personnel> query = (from p in this.Database.Personnels
                                where (search the array)
                                select p).ToList();

I want to add in the where clause a way to select only the users with the OrganizationId's in the array. So, in SQL where I would do something like "where OrganizationId = '12' or OrganizationId = '13' or OrganizatonId = '17'."

Can I do this fairly easily in Linq / .NET?
