I am currently trying to gather all information on my cache collection.

I am looping through the System."Collection.DictionaryEntry" class looking
for all the information i can get.
Currently i only seem to be able to get the Key and the Value.

Ultimately i am looking for:
The datetime the Cache was created
The datetime it was last accessed
The datetime it is set to expire
The sliding expiration time
The size of the cache
And any other information available.

IS this possible, is there another class i should be using or is their a way
to use the DictionaryEntry class i am not aware of

Thanks in advance

Grant

the dictionary cache only understands key value relationships. you cannot
glean that kind of information from the dictionary. i'm curious as to why
you need this information since the cache
is internally managed. i'd suggest you wrap the cache in a class and log
that info whenever you set the cache with data if you need to manage the
cache

Hi Alvin

I am currently running a number of web sites. I obviously use the cache to
store commonly used data.
When i make changes, i clear that cache to update it.
I was under the impression that i would not need to clear that cache, if it
wasn't used for a specified time - the time set by me in the TimeSpan

Currently i am inserting in to the Cache as follows:
Cache.Insert("SubnavForm", subnavForm, null, DateTime.MaxValue,
TimeSpan.FromMinutes(20));

However, after a full night of know use, the cache was not updated.
When i cleared the Cache by looping through the Collections.DictionaryEntry
collection, the Cache was then updated.
I wanted this information, to monitor my cache and find out why it was not
being cleared.

i don't see your callback function in there to reload the cache.
you need to point the cache to a callback function which reloads the cache
when the time expires.
makes sense?

ok, that makes perfect sense thank you.

still don't understand why you can't get comprehensive information from you
current cache
