DataRelationCollection::AddRange Method (array<DataRelation^>^)
Copies the elements of the specified DataRelation array to the end of the collection.
Assembly: System.Data (in System.Data.dll)
If BeginInit has been called, AddRange does not add any objects to the collection until EndInit is called. At the time that EndInit is called, the collection will be populated with the items specified in the most recent call to AddRange. If AddRange is called multiple times within a BeginInit / EndInit sequence, only those items specified in the most recent call to AddRange are added.
