'Declaration Public Class HttpListenerPrefixCollection Implements ICollection(Of String), IEnumerable(Of String), _ IEnumerable 'Usage Dim instance As HttpListenerPrefixCollection

The following code example creates an HttpListener and adds user-specified prefixes to its HttpListenerPrefixCollection.
// This example requires the System and System.Net namespaces. public static void SimpleListenerExample(string[] prefixes) { if (!HttpListener.IsSupported) { Console.WriteLine ("Windows XP SP2 or Server 2003 is required to use the HttpListener class."); return; } // URI prefixes are required, // for example "http://contoso.com:8080/index/". if (prefixes == null || prefixes.Length == 0) throw new ArgumentException("prefixes"); // Create a listener. HttpListener listener = new HttpListener(); // Add the prefixes. foreach (string s in prefixes) { listener.Prefixes.Add(s); } listener.Start(); Console.WriteLine("Listening..."); // Note: The GetContext method blocks while waiting for a request. HttpListenerContext context = listener.GetContext(); HttpListenerRequest request = context.Request; // Obtain a response object. HttpListenerResponse response = context.Response; // Construct a response. string responseString = "<HTML><BODY> Hello world!</BODY></HTML>"; byte[] buffer = System.Text.Encoding.UTF8.GetBytes(responseString); // Get a response stream and write the response to it. response.ContentLength64 = buffer.Length; System.IO.Stream output = response.OutputStream; output.Write(buffer,0,buffer.Length); // You must close the output stream. output.Close(); listener.Stop(); }
