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.

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.

System_CAPS_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 = gcnew StreamReader( ReceiveStream,encode );
Console::WriteLine( "\nResponse stream received" );
array<Char>^ read = gcnew array<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 = gcnew 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();
