HttpListenerResponse.Close Method

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()

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();
}
