示例1: NonblockingListener

Public Shared Sub NonblockingListener(ByVal prefixes As String())
    Dim listener As HttpListener = New HttpListener()

    For Each s As String In prefixes
        listener.Prefixes.Add(s)
    Next

    listener.Start()
    Dim result As IAsyncResult = listener.BeginGetContext(New AsyncCallback(AddressOf ListenerCallback), listener)
    ' Applications can do some work here while waiting for the 
    ' request. If no work can be done until you have processed a request,
    ' use a wait handle to prevent this thread from terminating
    ' while the asynchronous operation completes.
    Console.WriteLine("Waiting for request to be processed asyncronously.")
    result.AsyncWaitHandle.WaitOne()
    Console.WriteLine("Request processed asyncronously.")
    listener.Close()
End Sub

示例2: ListenerCallback

Public Shared Sub ListenerCallback(ByVal result As IAsyncResult)
    Dim listener As HttpListener = CType(result.AsyncState, HttpListener)
    ' Call EndGetContext to complete the asynchronous operation.
    Dim context As HttpListenerContext = listener.EndGetContext(result)
    Dim request As HttpListenerRequest = context.Request
    ' Obtain a response object.
    Dim response As HttpListenerResponse = context.Response
    ' Construct a response.
    Dim responseString As String = "<HTML><BODY> Hello world!</BODY></HTML>"
    Dim buffer As Byte() = System.Text.Encoding.UTF8.GetBytes(responseString)
    ' Get a response stream and write the response to it.
    response.ContentLength64 = buffer.Length
    Dim output As System.IO.Stream = response.OutputStream
    output.Write(buffer, 0, buffer.Length)
    ' You must close the output stream.
    output.Close()
End Sub
