缓存数据； ASP.NET

Question

NET and C# and writing an application that retrieves data from a database. I have attempted to cache the database locally in an attempt to speed up the application when doing a search. I have used the following lines of code to retrieve and save the data from the database in cache.

cached_database = HttpRuntime.Cache.Get(cacheID) as Entities;
if (cached_database == null)
{
    cached_database = InitializeDatabase(cacheID);
}



private Entities InitializeDatabase(string cacheID)
{
    var database = this.database;
    HttpRuntime.Cache.Insert(cacheID, database, null, DateTime.Now.AddMinutes(10), TimeSpan.Zero);

    return database;
}

I can see that I am able to return the correct cached data by looking at the debugger and the application still runs however it does not have any performance improvements. Am I doing this wrong, or is there possibility a better way to accomplish what I would like to do? Thanks.

I think you are caching the database object, an abstraction of the database. This object does the actual querying into the database when you access it's methods and properties. This is the expensive part - and this is why you don't get any effect from caching the database.

Cache the results, as suggested in the comments.
