List<T>.Enumerator.IEnumerator.Reset Method

Definition

Namespace:

System.Collections.Generic

Assemblies:

netstandard.dll, System.Collections.dll

Source:

List.cs

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

C#

void IEnumerator.Reset();

Implements

Reset()

Exceptions

InvalidOperationException

The collection was modified after the enumerator was created.

Remarks

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

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 IEnumerator.Reset throws an InvalidOperationException.
