Determines whether a set is a subset of a specified collection.

public:
 bool IsSubsetOf(System::Collections::Generic::IEnumerable ^ other);
public bool IsSubsetOf(System.Collections.Generic.IEnumerable other);
abstract member IsSubsetOf : seq<'T> -> bool
Public Function IsSubsetOf (other As IEnumerable(Of T)) As Boolean

Parameters

other
IEnumerable

The collection to compare to the current set.

Returns

Boolean

true if the current set is a subset of other; otherwise, false.

Exceptions

ArgumentNullException

other is null.

Remarks

If other contains the same elements as the current set, the current set is still considered a subset of other.

This method always returns false if the current set has elements that are not in other.
