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 ?

    Re: How to Caching of Hashtable in MVC?

    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:

    System.Web.HttpRuntime.Cache

    and could use

    HttpRuntime.Cache.Insert(
                                CacheKey,
                                CacheValue,
                                null,
                                DateTime.Now.AddMinutes(CacheDuration),
                                Cache.NoSlidingExpiration
                            );
                            Hashtable table1 = HttpRuntime.Cache[CacheKey] as Hashtable;
                            HttpRuntime.Cache.Remove(CacheKey);

    You'll also have access to

    System.Web.HttpContext.Current.Application

    and could use

    System.Web.HttpContext.Current.Application.Add("table1",myHashTable);
    Hashtable table1 = System.Web.HttpContext.Current.Application["table1"] as Hashtable;
