HashSet<T>.Enumerator.MoveNext Method

Microsoft Silverlight will reach end of support after October 2021. Learn more.

Advances the enumerator to the next element of the HashSet<T> collection.

Namespace:  System.Collections.Generic
Assembly:  System.Core (in System.Core.dll)

Syntax

'Declaration
Public Function MoveNext As Boolean
public bool MoveNext()

Return Value

Type: System.Boolean
true if the enumerator was successfully advanced to the next element; false if the enumerator has passed the end of the collection.

Implements

IEnumerator.MoveNext()

Exceptions

Exception Condition
InvalidOperationException

The collection was modified after the enumerator was created.

Remarks

After an enumerator is created, the enumerator is positioned before the first element in the collection, and the first call to the MoveNext method advances the enumerator to the first element of the collection.

If MoveNext passes the end of the collection, the enumerator is positioned after the last element in the collection and MoveNext returns false. When the enumerator is at this position, subsequent calls to MoveNext also return false.

An enumerator remains valid as long as the collection remains unchanged. If changes are made to the collection, such as adding, modifying, or deleting elements, the enumerator is irrecoverably invalidated.
