c# - Generic implementation of System.Runtime.Caching.MemoryCache -

is there generic alternative / implementation memorycache?

i know memorycache uses hashtable under hood, take transition using dictionary<,>, generic version of hashtable.

this provide type safety , provide performance benefits no boxing/unboxing.

edit: thing i'm interested in having different key type. default system.string.

not in base class library. you'd have roll own, though i, personally, make wrapper around memorycache provides api wish.

the type safety can handled in wrapper class. boxing/unboxing issue if storing value types (not classes), , then, minimal, it's unlikely you're pushing , pulling cache enough have true performance issue.

as type safety , usability, i've written own methods wrap memorycache item's calls in generic method, allows bit nicer usage api standpoint. easy - typically requires method like:

public t getitem<t>(string key) t : class {     return memorycache[key] t; } 

similarly, can make method set values same way.

this not supported directly memorycache, require fair bit of work make own key generation. 1 option make type safe wrapper provided func<t, string> generate string key based off value - allow generate cache entry type t. you'd have careful, of course, include data in string wanted part of comparison, however.
