When overridden in a descendant class, returns the data stream from the Internet resource.

Public Overridable Function GetResponseStream As Streampublic virtual Stream GetResponseStream()public:
virtual Stream^ GetResponseStream()abstract GetResponseStream : unit -> Stream
override GetResponseStream : unit -> Stream Return Value
Type: System.IOAn instance of the Stream class for reading data from the Internet resource.
| Exception | Condition |
|---|---|
| NotSupportedException | Any attempt is made to access the method, when the method is not overridden in a descendant class. |
The GetResponseStream method returns the data stream from the Internet resource.
Note |
|---|
The response stream must be closed to avoid running out of system resources. The response stream can be closed by calling Stream |
The following example uses GetResponseStream to return a StreamReader instance. A small local buffer is used to read data from the StreamReader and output it to the console.
