IEnumerableExtensionMethods.SetEqual<T> Method (IEnumerable<T>, IEnumerable<T>, IEqualityComparer<T>)

Checks whether the enumerable to compare with is equal to the source enumerable, element wise. If elements are in a different order, the method will still return true. This is different from SequenceEqual which does take order into account

Syntax

Copy

public static bool SetEqual<T>(
	this IEnumerable<T> source,
	IEnumerable<T> toCompareWith,
	IEqualityComparer<T> comparer
)

<ExtensionAttribute>
Public Shared Function SetEqual(Of T) ( 
	source As IEnumerable(Of T),
	toCompareWith As IEnumerable(Of T),
	comparer As IEqualityComparer(Of T)
) As Boolean

Parameters

source: Type: System.Collections.Generic.IEnumerable<T>
The source.
toCompareWith: Type: System.Collections.Generic.IEnumerable<T>
the sequence to compare with.
comparer: Type: System.Collections.Generic.IEqualityComparer<T>
The comparer.

Type Parameters

T: type of the element in the sequences to compare

Return Value

Type: Boolean
true if the source and the sequence to compare with have the same elements, regardless of ordering

Usage Note

In Visual Basic and C#, you can call this method as an instance method on any object of type IEnumerable<T>. When you use instance method syntax to call this method, omit the first parameter. For more information, see Extension Methods (Visual Basic) or Extension Methods (C# Programming Guide).
