public bool

IsProperSubsetOf(Generic.IEnumerable<T> other)

Determines whether the current set is a proper (strict) subset of a specified collection.

Returns <see langword="true" /> if the current set is a proper subset of other; otherwise <see langword="false" /> .

other The collection to compare to the current set.

public bool

IsProperSupersetOf(Generic.IEnumerable<T> other)

Determines whether the current set is a proper (strict) superset of a specified collection.

Returns <see langword="true" /> if the collection is a proper superset of other; otherwise <see langword="false" /> .

other The collection to compare to the current set.

public bool

IsSubsetOf(Generic.IEnumerable<T> other)

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

Returns <see langword="true" /> if the current set is a subset of other; otherwise <see langword="false" /> .

other The collection to compare to the current set.

public bool

IsSupersetOf(Generic.IEnumerable<T> other)

Determines whether the current set is a super set of a specified collection.

Returns <see langword="true" /> if the current set is a subset of other; otherwise <see langword="false" /> .

other The collection to compare to the current set.

public bool

Overlaps(Generic.IEnumerable<T> other)

Determines whether the current set overlaps with the specified collection.

Returns <see langword="true" /> if the current set and other share at least one common element; otherwise, <see langword="false" /> .

other The collection to compare to the current set.

public bool

SetEquals(Generic.IEnumerable<T> other)

Determines whether the current set and the specified collection contain the same elements.

Returns <see langword="true" /> if the current set is equal to other; otherwise, <see langword="false" /> .

other The collection to compare to the current set.

public bool

Equals(object obj)

Inherited from object

Determines whether the specified object is equal to the current object.

obj The object to compare with the current object.

protected void

Finalize()
