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
