Force all ASP.NET cache to expire

Question

Is there a method or something to force the expiration of all of the entries in the Cache collection of the HttpContext?

Answer 1

Try something like this:

var enumerator = HttpRuntime.Cache.GetEnumerator();
Dictionary<string, object> cacheItems = new Dictionary<string, object>();

while (enumerator.MoveNext())
    cacheItems.Add(enumerator.Key.ToString(), enumerator.Value);

foreach (string key in cacheItems.Keys)
    HttpRuntime.Cache.Remove(key);
