HttpListenerResponse.Close Method ()

Note: This method is new in the .NET Framework version 2.0.

Sends the response to the client and releases the resources held by this HttpListenerResponse instance.

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

public void Close ()
public void Close ()
public function Close ()

This method closes the response stream and the HttpListenerRequest associated with the response.

The following code example demonstrates calling this method to send a Forbidden (403) response to the client.

static string message403;
static void SendBadCertificateResponse(HttpListenerResponse response)
{
    StringBuilder message = new StringBuilder ();
    message.Append ("<HTML><BODY>");
    message.Append ("<p> Error message 403: Access is denied due to a missing or invalid client certificate.</p>");
    message.Append ("</BODY></HTML>");
    message403 = message.ToString();

    // Set up an authentication error response template.
    response.StatusCode = (int) HttpStatusCode.Forbidden;
    response.StatusDescription = "403 Forbidden";
    response.ProtocolVersion = new Version("1.1");
    response.SendChunked = false;
    
    // Turn the error message into a byte array using the 
    // encoding from the response when present.
    System.Text.Encoding encoding = response.ContentEncoding;
    if (encoding == null)
    {
        encoding = System.Text.Encoding.UTF8;
        response.ContentEncoding = encoding;
    }
        
    byte[] buffer = encoding.GetBytes (message403);
    response.ContentLength64 = buffer.Length;
    // Write the error message.
    System.IO.Stream stream = response.OutputStream;
    stream.Write(buffer,0,buffer.Length);
    // Send the response.
    response.Close();
}
