Parameters

The item removed from the Cache. If the value in the key parameter is not found, returns null.

The following example creates a RemoveItemFromCache method. When this method is called, it uses the Item property to check whether the cache contains an object that is associated with a Key1 key value. If it does, the Remove method is called to remove the object.

    if(Cache["Key1"] != null)
      Cache.Remove("Key1");

No need to check for existence?
If the return value is just null if the key is not found, then there's really no need to have a special method which checks for the existence of the key before calling the .Remove method right?
