Namespace: Microsoft.SqlServer.Dts.Tasks.Exec80PackageTask
Assembly: Microsoft.SqlServer.Exec80PackageTask (in microsoft.sqlserver.exec80packagetask.dll)

Syntax

'Declaration
Public Function MoveNext As Boolean

public bool MoveNext ()

public:
virtual bool MoveNext () sealed

public final boolean MoveNext ()

public final function MoveNext () : boolean

Return Value

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

Remarks

After an enumerator is created or after a call to Reset, an enumerator is positioned before the first element of the collection, and the first call to MoveNext moves the enumerator to the first element of the collection.

After the end of the collection is passed, subsequent calls to MoveNext 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. If the collection is modified between MoveNext and Current, Current will return the element that it is set to, even if the enumerator is already invalidated.
