HashSet<T>.Enumerator.IEnumerator.Reset Method

Definition

Namespace:

System.Collections.Generic

Assembly:

System.Collections.dll

Source:

HashSet.cs

Sets the enumerator to its initial position, which is before the first element in the collection.

 virtual void System.Collections.IEnumerator.Reset() = System::Collections::IEnumerator::Reset;

void IEnumerator.Reset ();

abstract member System.Collections.IEnumerator.Reset : unit -> unit
override this.System.Collections.IEnumerator.Reset : unit -> unit

Sub Reset () Implements IEnumerator.Reset

Implements

Reset()

Exceptions

InvalidOperationException

The collection was modified after the enumerator was created.

Remarks

After calling IEnumerator.Reset, you must call the MoveNext method to advance the enumerator to the first element of the collection before reading the value of the Current property.

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 and the next call to MoveNext or IEnumerator.Reset throws an InvalidOperationException.
