Remarks
Use this method to create an System.Collections.IEnumerator-implemented object that can be easily iterated through to get each item in the SelectedDatesCollection collection.
Use the IEnumerator.Current property to get the item currently pointed to in the collection.
Use the IEnumerator.MoveNext method to move to the next item in the collection.
Use the IEnumerator.Reset method to move the enumerator back to the initial position.
Note
The IEnumerator.MoveNext method needs to be called after creating an System.Collections.IEnumerator-implemented object or using the IEnumerator.Reset method to move the enumerator to the first item in the collection. Otherwise, the item represented by the IEnumerator.Current property is undefined.
