LINQ : The query results cannot be enumerated more than once [duplicate]

5

This is my code

 searchDataContext db = new searchDataContext();

    var query = (from p in db.SearchFirst(city, area)
                select new
                {
                    ID = p.Id,
                    Address = p.address,
                    Level = p.agahilevel

                });
    int count =query.Count();

    // records
    var q = query.Skip(Convert.ToInt32(start)).Take(Convert.ToInt32(width));

    if (q.Count() > 0)
    {
        int index = 0;
        str += "[";
        foreach (var row in q)
        {
            if (index == 0)

I have an error in this code

The query results cannot be enumerated more than once.
