AlgorithmsIsSubsetOfT Method (IEnumerableT, IEnumerableT)
Determines if one collection is a subset of another, considered as sets. The first set is a subset of the second set if every item in the first set also occurs in the second set. If an item appears X times in the first set, it must appear at least X times in the second set.

Namespace: X3Platform.Collections
Assembly: X3Platform.Support (in X3Platform.Support.dll) Version: 1.0.0.0 (2.0.0.0)
Syntax
Copy
public static bool IsSubsetOf<T>(
	IEnumerable<T> collection1,
	IEnumerable<T> collection2
)

Parameters

collection1
Type: System.Collections.GenericIEnumerableT
The first collection.
collection2
Type: System.Collections.GenericIEnumerableT
The second collection.

Type Parameters

T

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

Return Value

Type: Boolean
True if collection1 is a subset of collection2, considered as sets.
Exceptions
ExceptionCondition
ArgumentNullExceptioncollection1 or collection2 is null.
Remarks

The default sense of equality for T is used, as defined by T's implementation of IComparable<T>.Equals or object.Equals.

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