Question

I have problem with cache in my asp.net mvc3 application.

My code

using System.Web.Caching;
...
class RegularCacheProvider : ICacheProvider
{
    Cache cache ;

    public object Get(string name)
    {
        return cache[name];
    }

    public void Set(string name, object value)
    {
        cache.Insert(name, value);
    }

    public void Unset(string name)
    {
        cache.Remove(name);
    }
}

And I use singleton for give value for it :

School schoolSettings = (School)CacheProviderFactory.Cache.Get("SchoolSettings");
            if (schoolSettings == null)
            {
                CacheProviderFactory.Cache.Set("SchoolSettings", someObject);
            }

So in first use it does not work and give me an error cache[name] is null.

What I’m doing wrong?

Any help would be appreciated.

What about using the HttpRuntime.Cache, this example would cache for an hour?

HttpRuntime.Cache.Add("SchoolSettings", someObject, null, DateTime.Now.AddHours(1),
                       System.Web.Caching.Cache.NoSlidingExpiration,
                       System.Web.Caching.CacheItemPriority.Normal, null);
