re: Cache Abstraction

How does one use this? I've been looking for CacheProvider in the same way that it's possible to write a custom SessionStateProvider, but failing to find anything that suggests ASP.NET will let me swap out the basic cache for something else.

@Eric

Just sayin that its not necessarily wrong to return null. Guess its a choice rather a black and white situation.

Well, you can feel free to disagree, but I had to do something because the exception was crashing my app :) For me this works, as I can test for the returned value safely now...

@Eric

Yea... i was converting from VB to C# and didn't catch that. I'm not that much of a noob anymore :)

I disagree with you on the NullReferenceException. If the value is null in the cache, why return something? The manager class is just an API that delegates the functionality of the HttpCache.

Thanks for the awesome code sample!

I found one minor thing wrong with your C# example - you have to use brackets and not parens for accessing the cache like "HttpContext.Current.Cache[this.CacheKey]" instead of "HttpContext.Current.Cache(this.CacheKey)".

Also, I was getting some NullReferenceExceptions in that method, so I modified it like so and it works nicely:

public T Grab()

{

T temp;

try

{

temp = (T)HttpContext.Current.Cache[this.CacheKey];

}

catch (NullReferenceException)

{

temp = default(T);

}

return temp;

}
