    To make linq query faster

    Hi All,

    What should I do to make the following linq query faster? The database got heaps of records in it. This query actually followed by foreach loop and then again another query and foreach loop. It takes much time to load.
    Help will be appreciated. Thank you.

    var hours = from hr in objHours.Distinct()

    where hr.EmployeeID == empGuid && hr.JobId == j.JID && hr.CatId == j.CatId.ToInt() && hr.Date.Year == DateTime.Now.Year
    orderby hr.TID descending
    select new

    Hai AP,
    You can use instead lambda expression:

    var hours = objHours.Distinct()
    .Where(a=>a.EmployeeID == empGuid)
    .Where(a =>a.JobId == j.JID)
    .Where(a=>a.CatId == j.CatId.ToInt())
    .Where(a =>a.Date.Year == DateTime.Now.Year)

    Hope it will be helpful to you.
