Rate this:
I have a function, simple function from a public class.

That function creates an Hashtable object with information given from database, the part of his function like this:

try {

       while ( dataReader.Read() )


           Hashtable table1= new Hashtable();

           Hashtable table2= new Hashtable();


           table1.Add( dataReader["field1"].ToString(), Localization.English(dataReader["field1"]);


           table2.Add( dataReader["field2"].ToString(), Localization.French(dataReader["field2"]);



catch ( Exception e )


    Console.WriteLine( e.Message );


I want to cache these two Hashtables and use them in other classes. As I know, I cannot use HttpRuntime.Cache even if I used System.Web namespace.

I saw that HttpRuntime.Cache could be used in Model class.

Are there other way to cache these Hashtables ?

If you have two projects , like a Models or Entities project and your web project all you need to do is add a reference in the Models project to System.Web. If you did not add a reference to System.Web then you won't have access to HttpRuntime or HttpContect even though there is a namespace for System.Web.

After you do so, you'll have access to:


and could use








                        Hashtable table1 = HttpRuntime.Cache[CacheKey] as Hashtable;


You'll also have access to


and could use


Hashtable table1 = System.Web.HttpContext.Current.Application["table1"] as Hashtable;
