Remarks

Operation

This property contains the number of bytes of data in the response to the request associated with the current instance. For request methods that contain header information, the WebResponse.ContentLength does not include the length of the header information. The value of this property is set by the Content-Length header received in the response.

The System.Net.WebResponse class is abstract and does not provide an implementation for this property. This property throws NotSupportedException.

Note to Inheritors

This property is required to be overridden by classes that inherit from System.Net.WebResponse to set the content length as appropriate for the derived class.

Usage

Use this property to determine the number of bytes in the response.
