MemoryCache::Remove Method
Visual Studio 2010
Removes a cache entry from the cache.
Assembly: System.Runtime.Caching (in System.Runtime.Caching.dll)
Parameters
- key
- Type: System::String
A unique identifier for the cache entry to remove.
- regionName
- Type: System::String
A named region in the cache to which a cache entry was added. Do not pass a value for this parameter. This parameter is nullptr by default, because the MemoryCache class does not implement regions.
Return Value
Type: System::ObjectIf the entry is found in the cache, the removed cache entry; otherwise, nullptr.
| Exception | Condition |
|---|---|
| NotSupportedException | regionName is not nullptr. |
| ArgumentNullException | key is nullptr. |
If the entry specified by key exists in the cache, removing the item triggers any associated change monitors. If the removed item was associated with a CacheItemUpdateCallback object or a CacheItemRemovedCallback object, the reason passed to the callback is Removed.
