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

Here's is what I had made for something I was working on...

public void Flush()
{
    List cacheKeys = MemoryCache.Default.Select(kvp => kvp.Key).ToList();
    foreach (string cacheKey in cacheKeys)
    {
        MemoryCache.Default.Remove(cacheKey);
    }
}
