Solution 1

C#

public IQueryable GetJob_Allowance()
{   var ListOfIdsA = new List<int>(){1,2,3};
    return this.ObjectContext.Job_Allowance.Where(ds => ListOfIdsA.Contains(ds.Job_ID));
}

If you get job ids from some other table create job id list as below and use that.

C#

var ListOfIdsA = this.ObjectContext.Jobs.Select(j=>j.Job_id).ToList();
