Question

DataClassesDataContext dc = new DataClassesDataContext();
var summaryFieldDB = from b in dc.PropertyCompanies where (b.SummaryField.Contains(txtSearch)) select b;

Session["summaryField"] = summaryFieldDB;

now how can access to field summaryFiledDB???

if use this

  System.Data.Linq.Table<PropertyCompany> result = (System.Data.Linq.Table<PropertyCompany>)Session["summaryField"];

This line when run program say error:Unable to cast object of type ‘System.Data.Linq.DataQuery1[PropertyCompany]' to type 'System.Data.Linq.Table1[PropertyCompany]

if i use Store Procedure Like FullSearch

Session["search"]   = dc.FullSearch("anv", true, true, true, true, true, true, true, true, true, true, true);
System.Data.Linq.ISingleResult<FullSearchResult> b = (System.Data.Linq.ISingleResult<FullSearchResult>)Session["search"];
  foreach(var item in b)
  {
   //work with fields
  }

this work fine!!!

But I do not want to work with the Stored Procedure

I query isn’t a table. IMO, you should settle on something like a List<T> here:

Session["summaryField"] = summaryFieldDB.ToList();

and

var result = (List<PropertyCompany>)Session["summaryField"];
