HashSet<T> Constructor (IEqualityComparer<T>)

Microsoft Silverlight will reach end of support after October 2021. Learn more.

Initializes a new instance of the HashSet<T> class that is empty and uses the specified equality comparer for the set type.

Namespace: System.Collections.Generic
Assembly: System.Core (in System.Core.dll)

Syntax

'Declaration
Public Sub New ( _
    comparer As IEqualityComparer(Of T) _
)

public HashSet(
    IEqualityComparer<T> comparer
)

Parameters

comparer
Type: System.Collections.Generic.IEqualityComparer<T>
The IEqualityComparer<T> implementation to use when comparing values in the set, or nulla null reference (Nothing in Visual Basic) to use the default EqualityComparer<T> implementation for the set type.

Remarks

The capacity of a HashSet<T> object is the number of elements that the object can hold. A HashSet<T> object's capacity automatically increases as elements are added to the object.

This constructor is an O(1) operation.
