HttpListener.Stop 方法
定義
重要
部分資訊涉及發行前產品,在發行之前可能會有大幅修改。 Microsoft 對此處提供的資訊,不做任何明確或隱含的瑕疵擔保。
會導致這個執行個體停止接收新的傳入要求,並終止處理所有正在進行的要求。
public:
void Stop();
public void Stop ();
member this.Stop : unit -> unit
Public Sub Stop ()
例外狀況
此物件已關閉。
範例
下列程式代碼範例示範如何使用 Stop 方法來停止處理傳入要求。
// 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();
}
Public Shared Sub SimpleListenerExample(prefixes As String())
If Not HttpListener.IsSupported Then
Console.WriteLine("Windows XP SP2 or Server 2003 is required to use the HttpListener class.")
Return
End If
' URI prefixes are required,
' for example "http://contoso.com:8080/index/".
If prefixes Is Nothing Or prefixes.Length = 0 Then
Throw New ArgumentException("prefixes")
End If
' Create a listener
Dim listener = New HttpListener()
For Each s As String In prefixes
listener.Prefixes.Add(s)
Next
listener.Start()
Console.WriteLine("Listening...")
' Note: The GetContext method blocks while waiting for a request.
Dim context As HttpListenerContext = listener.GetContext()
Console.WriteLine("Listening...")
' Obtain a response object
Dim request As HttpListenerRequest = context.Request
' Construct a response.
Dim response As HttpListenerResponse = context.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()
listener.Stop()
End Sub
備註
如果這個實例已經停止,則呼叫這個方法沒有任何作用。
停止 HttpListener 物件之後,您可以使用 Start 方法來重新啟動它。
此方法不會封鎖以完成目前接受連線的傳送回應。
