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 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.

This constructor is an O(1) operation.
