Usage Note

In Visual Basic and C#, you can call this method as an instance method on any object of type IEnumerableT. When you use instance method syntax to call this method, omit the first parameter. For more information, see Extension Methods (Visual Basic) or Extension Methods (C# Programming Guide).

The specified collection can be added to the target collection if that is either an ICollectionT, IProducerConsumerCollectionT or IList implementation.

If target is neither a ListT nor an ISupportsRangeCollectionT implementation, then the elements of collection will only be added one by one.
