En ASP.NET, ¿cuál es la mejor manera de almacenar int en el sistema.web.caching?

Question

Actualmente, tengo que convertir int a string y almacenar en caché, muy complejo

int test = 123;
System.Web.HttpContext.Current.Cache.Insert("key", test.ToString()); // to save the cache
test = Int32.Parse(System.Web.HttpContext.Current.Cache.Get("key").ToString()); // to get the cache

¿Está aquí una manera más rápida sin cambiar de nuevo y otra vez?

Answer 1

You can store any kind of object in the cache. The method signature is:

Cache.Insert(string, object)

so, you don't need to convert to string before inserting. You will, however, need to cast when you retrieve from the cache:

int test = 123;
HttpContext.Current.Cache.Insert("key", test); 
object cacheVal = HttpContext.Current.Cache.Get("key");
if(cacheVal != null)
{
    test = (int)cacheVal;
}

This will incur a boxing/unboxing penalty with primitive types, but considerably less so than going via string each time.

Answer 2

You could implement your own method that handles it so the calling code looks cleaner.

public void InsertIntIntoCache( string key, int value )
{
   HttpContext.Current.Cache.Insert( key, value );
}

public int GetIntCacheValue( string key )
{
   return (int)HttpContext.Current.Cache[key];
}

int test = 123;
InsertIntIntoCache( "key", test );
test = GetIntCacheValue( "key" );
