ExtendedProperties.GetEnumerator Method

public:
 Microsoft::SqlServer::Dts::Runtime::ExtendedPropertyEnumerator ^ GetEnumerator();

public Microsoft.SqlServer.Dts.Runtime.ExtendedPropertyEnumerator GetEnumerator ();

override this.GetEnumerator : unit -> Microsoft.SqlServer.Dts.Runtime.ExtendedPropertyEnumerator

Public Function GetEnumerator () As ExtendedPropertyEnumerator

Returns

An ExtendedPropertyEnumerator enumerator for iterating over the collection.

Examples

The following code sample creates an ExtendedPropertyEnumerator using the GetEnumerator method, and then iterates over the collection.
