WebResponse.GetResponseStream Method
Assembly: System (in system.dll)
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.Close or Close |
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.
// Create a 'WebRequest' object with the specified url.
WebRequest myWebRequest = WebRequest.Create("http://www.contoso.com");
// Send the 'WebRequest' and wait for response.
WebResponse myWebResponse = myWebRequest.GetResponse();
// Obtain a 'Stream' object associated with the response object.
Stream ReceiveStream = myWebResponse.GetResponseStream();
Encoding encode = System.Text.Encoding.GetEncoding("utf-8");
// Pipe the stream to a higher level stream reader with the required encoding format.
StreamReader readStream = new StreamReader( ReceiveStream, encode );
Console.WriteLine("\nResponse stream received");
Char[] read = new Char[256];
// Read 256 charcters at a time.
int count = readStream.Read( read, 0, 256 );
Console.WriteLine("HTML...\r\n");
while (count > 0)
{
// Dump the 256 characters on a string and display the string onto the console.
String str = new String(read, 0, count);
Console.Write(str);
count = readStream.Read(read, 0, 256);
}
Console.WriteLine("");
// Release the resources of stream object.
readStream.Close();
// Release the resources of response object.
myWebResponse.Close();
// Create a 'WebRequest' object with the specified url.
WebRequest myWebRequest = WebRequest.Create(
"http://www.constoso.com");
// Send the 'WebRequest' and wait for response.
WebResponse myWebResponse = myWebRequest.GetResponse();
// Obtain a 'Stream' object associated with the response object.
Stream receiveStream = myWebResponse.GetResponseStream();
Encoding encode = System.Text.Encoding.GetEncoding("utf-8");
// Pipe the stream to a higher level stream reader with the required
// encoding format.
StreamReader readStream = new StreamReader(receiveStream, encode);
Console.WriteLine("\nResponse stream received");
char read[] = new char[256];
// Read 256 charcters at a time.
int count = readStream.Read(read, 0, 256);
Console.WriteLine("HTML...\r\n");
while (count > 0) {
// Dump the 256 characters on a string and display the string
// onto the console.
String str = new String(read, 0, count);
Console.Write(str);
count = readStream.Read(read, 0, 256);
}
Console.WriteLine("");
// Release the resources of stream object.
readStream.Close();
// Release the resources of response object.
myWebResponse.Close();

Using Streams on the NetworkI am disappointed that this kind of basic usage information is not available. It is as if the help is a brief reminder for people who already know the answer, rather than a a more complete resource for people who don't. I wouldn't need to look here if I knew the answer !
