Constructors

ConcurrentSet()

Initializes a new instance of the ConcurrentSet<T> class with the default concurrency level.

Declaration

public ConcurrentSet()

ConcurrentSet(IEqualityComparer<T>)

Initializes a new instance of the ConcurrentSet<T> class using the specified equality comparer.

Declaration

public ConcurrentSet(IEqualityComparer<T> equalityComparer)

Parameters

Type	Name	Description
IEqualityComparer<T>	equalityComparer	The equality comparer for values in the set.

Properties

Count

Gets the number of elements in the set.

Declaration

public int Count { get; }

Property Value

Type	Description
int	The number of elements in the set.

IsEmpty

Gets a value indicating whether the set is empty.

Declaration

public bool IsEmpty { get; }

Property Value

Type	Description
bool	true if the set is empty; otherwise, false.

IsReadOnly

Gets a value indicating whether the ICollection<T> is read-only.

Declaration

public bool IsReadOnly { get; }

Property Value

Type	Description
bool	true if the ICollection<T> is read-only; otherwise, false.

Methods

Add(T)

Attempts to add a value to the set.

Declaration

public bool Add(T value)

Parameters

Type	Name	Description
T	value	The value to add.

Returns

Type	Description
bool	true if the value was added to the set. If the value already exists, this method returns false.

Clear()

Clear the set.

Declaration

public void Clear()

Contains(T)

Determine whether the given value is in the set.

Declaration

public bool Contains(T item)

Parameters

Type	Name	Description
T	item	The value to test.

Returns

Type	Description
bool	true if the set contains the specified value; otherwise, false.

CopyTo(T[], int)

Copies the elements of the ICollection<T> to an Array, starting at a particular Array index.

Declaration

public void CopyTo(T[] array, int arrayIndex)

Parameters

Type	Name	Description
T[]	array	The one-dimensional Array that is the destination of the elements copied from ICollection<T>. The Array must have zero-based indexing.
int	arrayIndex	The zero-based index in array at which copying begins.

Exceptions

Type	Condition
ArgumentNullException	array is null.
ArgumentOutOfRangeException	arrayIndex is less than 0.
ArgumentException	The number of elements in the source ICollection<T> is greater than the available space from arrayIndex to the end of the destination array.

GetEnumerator()

Obtain an enumerator that iterates through the elements in the set.

Declaration

public ConcurrentSet<T>.KeyEnumerator GetEnumerator()

Returns

Type	Description
ConcurrentSet<T>.KeyEnumerator	An enumerator for the set.

Remove(T)

Attempts to remove a value from the set.

Declaration

public bool Remove(T item)

Parameters

Type	Name	Description
T	item	The value to remove.

Returns

Type	Description
bool	true if the value was removed successfully; otherwise false.
