Örnekler

Aşağıdaki kod örneğinde bu yöntemin çağrılması gösterilmektedir. listener değişkeni bir HttpListener nesneyi barındırıyor.

// This example requires the System and System.Net namespaces.
public static string ClientInformation(HttpListenerContext context)

}

public static void SimpleListenerWithAuthentication(string[] prefixes)
{
    if (!HttpListener.IsSupported)

    // for example "http://contoso.com:8080/index/".
    if (prefixes == null || prefixes.Length == 0)

    // Set up a listener.
    HttpListener listener = new HttpListener();
    foreach (string s in prefixes)

    // Construct a response.
    string clientInformation = ClientInformation(context);
    byte[] buffer = System.Text.Encoding.UTF8.GetBytes("<HTML><BODY> " + clientInformation + "</BODY></HTML>");
    // Get a response stream and write the response to it.
    response.ContentLength64 = buffer.Length;
