--i have a autocomplete textbox. Now in the autocomplete textbox, user may enter UnitId or Name.

if UnitId is entered 3
result should be UnitId ascending

32    xyz1
37    xyz2
345   xyz
3149  Sandhurst

--if i enter Name result should be in order by Name ascending. If i enter 'x'
345   xyz
32    xyz1
37    xyz2

--But My linq doesnot fetch in order by. In database unitid is varchar.

kindly help me in writing the Linq that will order by .

So far my linq is as below.
------------------------------Linq---------------------------------------

public List<BusinessUnit> GetStoresNameId(string StoreIdName)
       {
           try
           {

               List<BusinessUnit> data = (from r in GetStoreHierarchy().Where(p => p.ParentId != "1" && p.ParentId != null).ToList()
                                          where r.UnitId.ToUpper().StartsWith(StoreIdName.ToUpper()) || r.Name.ToUpper().StartsWith(StoreIdName.ToUpper())
                                          select new BusinessUnit { UnitId = r.UnitId, Name = r.Name }).Distinct().Take(10).ToList();
               return data;

           }
           catch (Exception ex)
           {
               //_log.Error("GetStores", ex);
               throw ex;
           }

       }

-- I want to include orderby in my linq. 

-- If in the function <pre lang="vb">GetStoresNameId(string StoreIdName)

List<BusinessUnit> data = (from r in GetStoreHierarchy().Where(p => p.ParentId != "1" && p.ParentId != null).ToList()
                                         where r.UnitId.ToUpper().StartsWith(StoreIdName.ToUpper()) || r.Name.ToUpper().StartsWith(StoreIdName.ToUpper())
                                         select new BusinessUnit { UnitId = r.UnitId, Name = r.Name }).Distinct().OrderBy(x=>(Convert.ToInt32(x.UnitId))).Take(10).ToList();
              return data;
