HashSet<'T> Constructor (IEqualityComparer<'T>)

 

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)

new : 
        comparer:IEqualityComparer<'T> -> HashSet

Parameters

comparer
Type: System.Collections.Generic.IEqualityComparer<'T>

The IEqualityComparer<'T> implementation to use when comparing values in the set, or null to use the default EqualityComparer<'T> implementation for the set type.

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.
