HashSet Constructor (ICollection, Int32, IHashCodeProvider, IComparer)

Initializes a new instance of the HashSet class that contains elements copied from the specified collection with the specified initial capacity and using the default load factor, the specified hash code provider and the specified comparer.

[Visual Basic]
Overloads Public Sub New( _
   ByVal collection As ICollection, _
   ByVal initialCapacity As Integer, _
   ByVal hcp As IHashCodeProvider, _
   ByVal comparer As IComparer _
)

[C#]
public HashSet(
   ICollection collection,
   int initialCapacity,
   IHashCodeProvider hcp,
   IComparer comparer
);

Parameters

collection: The ICollection whose elements are copied to the new list.
initialCapacity: The approximate number of elements that the HashSet can initially contain.
hcp: The IHashCodeProvider that supplies the hash codes for all elements in the HashSet.
-or-
A null reference (Nothing in Visual Basic) to use the default hash code provider, which is each element's implementation of GetHashCode.
comparer: The IComparer to use to determine whether two elements are equal.
-or-
A null reference (Nothing in Visual Basic) to use the default comparer, which is each element's implementation of Equals.
