public:

Public Overridable ReadOnly Property AllKeys As String()
Property Value
A String array that contains all the keys of the NameValueCollection.
Remarks
If the collection is empty, this method returns an empty String array, not null
.
The arrays returned by AllKeys are cached for better performance and are automatically refreshed when the collection changes. A derived class can invalidate the cached version by calling InvalidateCachedArrays, thereby forcing the arrays to be recreated.
This method is an O(n
) operation, where n
is Count.
