HashSet<T>.CreateSetComparer Method

Definition

Namespace:

System.Collections.Generic

Assembly:

System.Collections.dll

Source:

HashSet.cs

Returns an IEqualityComparer object that can be used for equality testing of a HashSet<T> object.

public:
 static System::Collections::Generic::IEqualityComparer<System::Collections::Generic::HashSet<T> ^> ^ CreateSetComparer();

public static System.Collections.Generic.IEqualityComparer<System.Collections.Generic.HashSet<T>> CreateSetComparer ();

static member CreateSetComparer : unit -> System.Collections.Generic.IEqualityComparer<System.Collections.Generic.HashSet<'T>>

Public Shared Function CreateSetComparer () As IEqualityComparer(Of HashSet(Of T))

Returns

IEqualityComparer<HashSet<T>>

An IEqualityComparer object that can be used for deep equality testing of the HashSet<T> object.

Remarks

The IEqualityComparer object checks for equality at only one level; however, you can chain together comparers at additional levels to perform deeper equality testing.

Calling this method is an O(1) operation.
