public static bool IsProperSubsetOf<T>(
	IEnumerable<T> collection1,
	IEnumerable<T> collection2,
	IEqualityComparer<T> equalityComparer
)

public:
generic<typename T>
static bool IsProperSubsetOf(
	IEnumerable<T>^ collection1, 
	IEnumerable<T>^ collection2, 
	IEqualityComparer<T>^ equalityComparer
)

Parameters

collection1

Type: System.Collections.GenericIEnumerableT
The first collection.

collection2

Type: System.Collections.GenericIEnumerableT
The second collection.

equalityComparer

Type: System.Collections.GenericIEqualityComparerT
The IEqualityComparer<T> used to compare items for equality. Only the Equals and GetHashCode member functions of this interface are called.

Type Parameters

T

[Missing <typeparam name="T"/> documentation for "M:X3Platform.Collections.Algorithms.IsProperSubsetOf``1(System.Collections.Generic.IEnumerable{``0},System.Collections.Generic.IEnumerable{``0},System.Collections.Generic.IEqualityComparer{``0})"]

Return Value

If both collections are Set, Bag, OrderedSet, or OrderedBag collections, it is more efficient to use the IsSubsetOf method on that class.
