HttpListener.Close Method

Definition

Namespace:

System.Net

Assembly:

System.Net.HttpListener.dll

Source:

HttpListener.cs

Shuts down the HttpListener.

public:
 void Close();

public void Close ();

member this.Close : unit -> unit

Public Sub Close ()

Examples

The following code example demonstrates calling the Close method:

public static void NonblockingListener(string [] prefixes)
{
    HttpListener listener = new HttpListener();
    foreach (string s in prefixes)
    {
        listener.Prefixes.Add(s);
    }
    listener.Start();
    IAsyncResult result = listener.BeginGetContext(new AsyncCallback(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();
}

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

Remarks

After calling this method, you can no longer use the HttpListener object. To temporarily pause an HttpListener object, use the Stop method.

This method shut downs the HttpListener object without processing queued requests. Any pending requests are unable to complete.

Notes to Callers

This member outputs trace information when you enable network tracing in your application. For more information, see Network Tracing in the .NET Framework.
