Syntax

'Declaration
Public ReadOnly Property Count As Integer
public int Count { get; }

Property Value

Type: System.Int32
The number of elements that are contained in the set.

Implements

ICollection<T>.Count

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.

The capacity is always greater than or equal to Count. If Count exceeds the capacity while adding elements, the capacity is set to the first prime number that is greater than double the previous capacity.

Retrieving the value of this property is an O(1) operation.
