  System.Collections.IDictionaryEnumerator Interface
Calling writeTextBlock Collections are classes that literally hold collections of data, such as lists, queues and stacks. IDictionaryEnumerator defines the behaviour of a class that allows the items in a collection to be read (but not updated) in sequence - specifically, classes that have DictionaryEntry elements.
The IDictionaryEnumerator interface provides the following methods (inherited from IEnumerator) :
MoveNext Position to the next item in the list (enumeration). This must be used when first using an IDictionaryEnumerator, or after a Reset, since position is before the first item
Reset repositions to before the first item in the list (enumeration).

A IDictionaryEnumerator is returned by the GetEnumerator method of System.Collections.SortedList. After writeTextBlock
Entry  DictionaryEntry  When implemented by a class, gets both the key and the value of the current dictionary entry.
Key  Object  When implemented by a class, gets the key of the current dictionary entry.
Value  Object  When implemented by a class, gets the value of the current dictionary entry.
