Przykłady

Poniższy przykład ilustruje sposób użycia GetResponseStream, aby zwrócić wystąpienie Stream używane do odczytu odpowiedzi z serwera.The following example demonstrates how to use GetResponseStream to return the Stream instance used to read the response from the server.

// Creates an HttpWebRequest with the specified URL.
HttpWebRequest^ myHttpWebRequest = (HttpWebRequest^)( WebRequest::Create( url ) );
// Sends the HttpWebRequest and waits for the response.
HttpWebResponse^ myHttpWebResponse = (HttpWebResponse^)( myHttpWebRequest->GetResponse() );
// Gets the stream associated with the response.
Stream^ receiveStream = myHttpWebResponse->GetResponseStream();
Encoding^ encode = System::Text::Encoding::GetEncoding( "utf-8" );
// Pipes the stream to a higher level stream reader with the required encoding format.
StreamReader^ readStream = gcnew StreamReader( receiveStream,encode );
Console::WriteLine( "\r\nResponse stream received." );
array<Char>^ read = gcnew array<Char>(256);
// Reads 256 characters at a time.
int count = readStream->Read( read, 0, 256 );
Console::WriteLine( "HTML...\r\n" );
while ( count > 0 )
{
   // Dumps the 256 characters on a String* and displays the String* to the console.
   String^ str = gcnew String( read,0,count );
   Console::Write( str );
   count = readStream->Read( read, 0, 256 );
}
Console::WriteLine( "" );
// Releases the resources of the response.
myHttpWebResponse->Close();
// Releases the resources of the Stream.
readStream->Close();
// Creates an HttpWebRequest with the specified URL. 
    HttpWebRequest myHttpWebRequest = (HttpWebRequest)WebRequest.Create(url); 
    // Sends the HttpWebRequest and waits for the response.			
    HttpWebResponse myHttpWebResponse = (HttpWebResponse)myHttpWebRequest.GetResponse(); 
    // Gets the stream associated with the response.
    Stream receiveStream = myHttpWebResponse.GetResponseStream();
    Encoding encode = System.Text.Encoding.GetEncoding("utf-8");
    // Pipes the stream to a higher level stream reader with the required encoding format. 
    StreamReader readStream = new StreamReader( receiveStream, encode );
Console.WriteLine("\r\nResponse stream received.");
    Char[] read = new Char[256];
    // Reads 256 characters at a time.    
    int count = readStream.Read( read, 0, 256 );
    Console.WriteLine("HTML...\r\n");
    while (count > 0) 
        {
            // Dumps the 256 characters on a string and displays the string to the console.
            String str = new String(read, 0, count);
            Console.Write(str);
            count = readStream.Read(read, 0, 256);
        }
    Console.WriteLine("");
    // Releases the resources of the response.
    myHttpWebResponse.Close();
    // Releases the resources of the Stream.
    readStream.Close();
' Creates an HttpWebRequest for the specified URL. 
Dim myHttpWebRequest As HttpWebRequest = CType(WebRequest.Create(url), HttpWebRequest)
' Sends the request and waits for a response.			
Dim myHttpWebResponse As HttpWebResponse = CType(myHttpWebRequest.GetResponse(), HttpWebResponse)
' Calls the method GetResponseStream to return the stream associated with the response.
Dim receiveStream As Stream = myHttpWebResponse.GetResponseStream()
Dim encode As Encoding = System.Text.Encoding.GetEncoding("utf-8")
' Pipes the response stream to a higher level stream reader with the required encoding format. 
Dim readStream As New StreamReader(receiveStream, encode)
Console.WriteLine(ControlChars.Lf + ControlChars.Cr + "Response stream received")
Dim read(256) As [Char]
' Reads 256 characters at a time.    
Dim count As Integer = readStream.Read(read, 0, 256)
Console.WriteLine("HTML..." + ControlChars.Lf + ControlChars.Cr)
While count > 0
    ' Dumps the 256 characters to a string and displays the string to the console.
    Dim str As New [String](read, 0, count)
    Console.Write(str)
    count = readStream.Read(read, 0, 256)
End While
Console.WriteLine("")
' Releases the resources of the Stream.
readStream.Close()
 ' Releases the resources of the response.
myHttpWebResponse.Close()

Uwagi

Uwaga

Należy wywołać Stream.Close lub metodę HttpWebResponse.Close, aby zamknąć strumień i zwolnić połączenie w celu ponownego użycia.You must call either the Stream.Close or the HttpWebResponse.Close method to close the stream and release the connection for reuse. Nie jest konieczne Wywołaj obu Stream.Close i HttpWebResponse.Close, ale nie spowoduje to błędu.It is not necessary to call both Stream.Close and HttpWebResponse.Close, but doing so does not cause an error. Niepowodzenie zamknięcia strumienia spowoduje nieprzerwane działanie aplikacji.Failure to close the stream will cause your application to run out of connections.
