ISet<T>.IsSubsetOf(IEnumerable<T>) Method

Definition

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

C#
public bool IsSubsetOf(System.Collections.Generic.IEnumerable<T> other);

Parameters

other
IEnumerable<T>

The collection to compare to the current set.

Returns

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

Exceptions

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.
