IRemoteArgumentEnumeratorContract.MoveNext Method

  • Reference

Definition

Namespace:
System.AddIn.Contract.Collections
Assembly:
System.AddIn.Contract.dll

Advances the enumerator to the next element of the collection.

public:
 bool MoveNext();
public bool MoveNext ();
abstract member MoveNext : unit -> bool
Public Function MoveNext () As Boolean

Returns

Boolean

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

Exceptions

InvalidOperationException

The collection was modified after the enumerator was created.

Remarks

After an enumerator is created or after the Reset method is called, an enumerator is positioned before the first element of the collection. The first call to the MoveNext method moves 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 until Reset is called.

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 Reset throws an InvalidOperationException.
