Contoh

Contoh berikut menunjukkan cara menggunakan GetResponseStream untuk mengembalikan instans yang Stream digunakan untuk membaca respons dari 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()

Catatan

Anda harus memanggil salah Stream.Closesatu metode , Stream.Dispose, HttpWebResponse.Close, atau HttpWebResponse.Dispose untuk menutup aliran dan merilis koneksi untuk digunakan kembali. Tidak perlu menutup atau membuang instans Stream dan HttpWebResponse , tetapi melakukannya tidak menyebabkan kesalahan. Kegagalan untuk menutup atau membuang aliran akan menyebabkan aplikasi Anda kehabisan koneksi.
