How do I clear a System.Runtime.Caching.MemoryCache

Question

I use a System.Runtime.Caching.MemoryCache to hold items which never expire. However, at times I need the ability to clear the entire cache. How do I do that?

Answer 1

Check out this post, and specifically, the answer that Thomas F. Abraham posted. It has a solution that enables you to clear the entire cache or a named subset.

The key thing here is:

// Cache objects are obligated to remove entry upon change notification.
base.OnChanged(null);

I've implemented this myself, and everything seems to work just fine.
