Count

Gets the number of elements in the set.

public int Count { get; }

Property Value

int

ReaderWriterLock

public ReaderWriterLockSlim ReaderWriterLock { get; }

Property Value

ReaderWriterLockSlim

Methods

Add(T)

Adds an element to the set.

public bool Add(T item)

Parameters

item T

The element to add.

Returns

bool

true if the element is added to the set; false if the element is already present.

Clear()

Removes all elements from the set.

public void Clear()

CloneContent()

Creates a new HashSet that contains the same elements as the current set.

public HashSet<T> CloneContent()

Returns

HashSet<T>

A new HashSet that contains the same elements as the current set.

Contains(T)

Determines whether the set contains the specified element.

public bool Contains(T item)

Parameters

item T

The element to locate.

Returns

bool

true if the set contains the specified element; otherwise, false.

Dispose()

Performs application-defined tasks associated with freeing, releasing, or resetting unmanaged resources.

public void Dispose()

Dispose(bool)

Releases the unmanaged resources used by the ThreadSafeSet<T> and optionally releases the managed resources.

protected virtual void Dispose(bool disposing)

Parameters

disposing bool

true to release both managed and unmanaged resources; false to release only unmanaged resources.

EnsureCapacity(int)

Ensures that the set can hold the specified number of elements without growing.

public int EnsureCapacity(int capacity)

Parameters

capacity int

The minimum capacity to ensure.

Returns

int

The new capacity of the set.

Remove(T)

Removes the specified element from the set.

public bool Remove(T item)

Parameters

item T

The element to remove.

Returns

bool

true if the element is successfully found and removed; otherwise, false.

TrimExcess()

Sets the capacity of the set to the actual number of elements it contains.

public void TrimExcess()

TryGetValue(T, out T)

Attempts to get the actual value of an element equal to the specified value.

public bool TryGetValue(T equalValue, out T actualValue)

Parameters

equalValue T

The value to search for.

actualValue T

When this method returns, contains the actual value if found; otherwise, the default value for the type.

Returns

bool

true if the set contains an element equal to the specified value; otherwise, false.

UnionWith(IEnumerable<T>)

Modifies the current set to contain all elements that are present in itself, the specified collection, or both.

public void UnionWith(IEnumerable<T> other)

Parameters

other IEnumerable<T>

The collection to compare to the current set.
