Description
Reads and returns the value-type indicator of the next item in the reader object's stream without moving the stream position.
NextValue is used internally by reader methods when the subsequent processing depends on a type of the data item about to be read from the reader object's stream.
After reading the value-type indicator of the next data item, NextValue returns the stream position back before the value-type indicator.
