Syntax

public class ConcurrentSet<T> : ICollection<T>, IEnumerable<T>, IEnumerable

Type Parameters

Name	Description
T	The type of elements in the set.

Constructors

ConcurrentSet()

Initializes a new, empty instance of the ConcurrentSet<T> class.

Declaration

public ConcurrentSet()

ConcurrentSet(IEnumerable<T>)

Initializes a new instance of the ConcurrentSet<T> class that contains elements copied from the specified collection.

Declaration

public ConcurrentSet(IEnumerable<T> collection)

Parameters

Type	Name	Description
IEnumerable<T>	collection	The collection whose elements are copied to the new set.

ConcurrentSet(IEnumerable<T>, IEqualityComparer<T>)

Initializes a new instance of the ConcurrentSet<T> class that contains elements copied from the specified collection and uses the specified equality comparer.

Declaration

public ConcurrentSet(IEnumerable<T> collection, IEqualityComparer<T> comparer)

Parameters

Type	Name	Description
IEnumerable<T>	collection	The collection whose elements are copied to the new set.
IEqualityComparer<T>	comparer	The equality comparer to use for the set.

ConcurrentSet(IEqualityComparer<T>)

Initializes a new, empty instance of the ConcurrentSet<T> class that uses the specified equality comparer.

Declaration

public ConcurrentSet(IEqualityComparer<T> comparer)

Parameters

Type	Name	Description
IEqualityComparer<T>	comparer	The equality comparer to use for the set.

ConcurrentSet(int, IEnumerable<T>, IEqualityComparer<T>)

Initializes a new instance of the ConcurrentSet<T> class that contains elements copied from the specified collection, has the specified concurrency level, and uses the specified equality comparer.

Declaration

public ConcurrentSet(int concurrencyLevel, IEnumerable<T> collection, IEqualityComparer<T> comparer)

Parameters

Type	Name	Description
int	concurrencyLevel	The estimated number of threads that will update the set concurrently.
IEnumerable<T>	collection	The collection whose elements are copied to the new set.
IEqualityComparer<T>	comparer	The equality comparer to use for the set.

ConcurrentSet(int, int)

Initializes a new, empty instance of the ConcurrentSet<T> class with the specified concurrency level and capacity.

Declaration

public ConcurrentSet(int concurrencyLevel, int capacity)

Parameters

Type	Name	Description
int	concurrencyLevel	The estimated number of threads that will update the set concurrently.
int	capacity	The initial number of elements that the set can contain.

ConcurrentSet(int, int, IEqualityComparer<T>)

Initializes a new, empty instance of the ConcurrentSet<T> class with the specified concurrency level, capacity, and equality comparer.

Declaration

public ConcurrentSet(int concurrencyLevel, int capacity, IEqualityComparer<T> comparer)

Parameters

Type	Name	Description
int	concurrencyLevel	The estimated number of threads that will update the set concurrently.
int	capacity	The initial number of elements that the set can contain.
IEqualityComparer<T>	comparer	The equality comparer to use for the set.

Properties

Count

Declaration

public bool TryAdd(T item)

Parameters

Type	Name	Description
