Ejemplos

En el ejemplo de código siguiente se muestra cómo establecer el valor de esta propiedad.


// When the client is not authenticated, there is no Identity.
if (context.User == null)
{
    message.Append ("<HTML><BODY><p> Hello local user! </p></BODY></HTML>");
}
else
{
    // Get the requester's identity.
    System.Security.Principal.WindowsIdentity identity = WindowsIdentity.GetCurrent();
    // Construct the response body.
    message.AppendFormat ("<HTML><BODY><p> Hello {0}!<br/>",
        identity.Name);
    message.AppendFormat ("You were authenticated using {0}.</p>",
        identity.AuthenticationType);
    message.Append ("</BODY></HTML>");
}

// Configure the response.
HttpListenerResponse response = context.Response;

// Use the encoding from the response if one has been set.
// Otherwise, use UTF8.
System.Text.Encoding encoding = response.ContentEncoding;
if (encoding == null)
{
    encoding = System.Text.Encoding.UTF8;
    response.ContentEncoding = encoding;
}
byte[] buffer = encoding.GetBytes (message.ToString ());
response.ContentLength64 = buffer.Length;
response.StatusCode = (int) HttpStatusCode.OK;
response.StatusDescription = "OK";
response.ProtocolVersion = new Version ("1.1");
// Don't keep the TCP connection alive;
// We don't expect multiple requests from the same client.
response.KeepAlive = false;
// Write the response body.
System.IO.Stream stream = response.OutputStream;
stream.Write(buffer, 0, buffer.Length);

    message.AppendFormat("You were authenticated using {0}.</p>", identity.AuthenticationType)
    message.Append("</BODY></HTML>")
End If
