The Segment object will contain data describing the data that was sent or received. For example, the Segment object will contain the data itself, the amount of bytes sent,' and whether the Segment object was created as a result of data being sent or received.
To access the data contained within the Segment object, simply access the properties of the Segment object. As a shortcut, you can simply get all data contained within the Segment object by using the Segment.ToString method.
