WebResponse.GetResponseStream Method

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

Namespace:  System.Net
Assembly:  System (in System.dll)

public virtual Stream GetResponseStream()

Return Value

Type: System.IO.Stream
An instance of the Stream class for reading data from the Internet resource.

ExceptionCondition
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.

NoteNote:

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(S"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(S"utf-8");

// Pipe the stream to a higher level stream reader with the required encoding format.
StreamReader* readStream = new StreamReader(ReceiveStream, encode);
Console::WriteLine(S"\nResponse stream received");
Char read[] = new Char[256];

// Read 256 charcters at a time.
int count = readStream->Read(read, 0, 256);
Console::WriteLine(S"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(S"");
// Release the resources of stream object.
readStream->Close();

// Release the resources of response object.
myWebResponse->Close();
