Assembly: System (in System.dll)
Any attempt is made to get or set the property, when the property is not overridden in a descendant class.
The property contains the number of bytes of data sent to the Internet resource by the WebRequest instance.
The WebRequest class is an abstract class. The actual behavior of WebRequest instances at run time is determined by the descendant class returned by the WebRequest.Create method. For more information about default values and exceptions, see the documentation for the descendant classes, such as HttpWebRequest and FileWebRequest.
