Determines whether a SortedSet<T> object is a proper subset of the specified collection.
public:
virtual bool IsProperSubsetOf(System::Collections::Generic::IEnumerable<T> ^ other);
public bool IsProperSubsetOf(System.Collections.Generic.IEnumerable<T> other);
abstract member IsProperSubsetOf : seq<'T> -> bool
override this.IsProperSubsetOf : seq<'T> -> bool
Public Function IsProperSubsetOf (other As IEnumerable(Of T)) As Boolean
- other
- IEnumerable<T>
The collection to compare to the current SortedSet<T> object.
true
if the SortedSet<T> object is a proper subset of other
; otherwise, false
.
other
is null
.
An empty set is a proper subset of any other collection. Therefore, this method returns true
if the collection represented by the current SortedSet<T> object is empty unless the other
parameter is also an empty set.
This method always returns false
if Count is greater than or equal to the number of elements in other
.
If the collection represented by other
is a SortedSet<T> collection with the same equality comparer as the current SortedSet<T> object, then this method is an O(n)
operation. Otherwise, this method is an O(n + m)
operation, where n
is Count and m
is the number of elements in other
.
