Parameters

key String

The unique identifier for the cache entry.

If the entry is found in the cache, a reference to the value in the cache container of the removed cache entry; otherwise, null.

RemoveAll(String)

Removes all entries associated with the ns contained in the cache.

void RemoveAll(string ns = null)
