WebResponse.Close Metodo

Definizione

Quando sottoposto a override in una classe discendente, chiude il flusso di risposta.When overridden by a descendant class, closes the response stream.

public:
 virtual void Close();
public virtual void Close ();
abstract member Close : unit -> unit
override this.Close : unit -> unit
Public Overridable Sub Close ()

Eccezioni

Viene eseguito un tentativo di accedere al metodo quando quest'ultimo non è sottoposto a override in una classe discendente.Any attempt is made to access the method, when the method is not overridden in a descendant class.

Esempi

Nell'esempio seguente viene usato Close il metodo per chiudere WebResponsel'oggetto.The following example uses the Close method to close the WebResponse.

// Create a 'WebRequest' object with the specified url.
WebRequest^ myWebRequest = WebRequest::Create( "http://www.contoso.com" );
// Send the 'WebRequest' and wait for response.
WebResponse^ myWebResponse = myWebRequest->GetResponse();

// Process the response here.
Console::WriteLine( "\nResponse Received::Trying to Close the response stream.." );
// Release resources of response Object*.
myWebResponse->Close();
Console::WriteLine( "\nResponse Stream successfully closed" );
// Create a 'WebRequest' object with the specified url. 	
WebRequest myWebRequest = WebRequest.Create("http://www.contoso.com"); 
// Send the 'WebRequest' and wait for response.	
WebResponse myWebResponse = myWebRequest.GetResponse(); 

// Process the response here.
Console.WriteLine("\nResponse Received.Trying to Close the response stream..");
// Release resources of response object.
myWebResponse.Close();
Console.WriteLine("\nResponse Stream successfully closed");
' Create a 'WebRequest' object with the specified url 	
Dim myWebRequest As WebRequest = WebRequest.Create("www.contoso.com")
' Send the 'WebRequest' and wait for response.	
Dim myWebResponse As WebResponse = myWebRequest.GetResponse()

'  Process the response here
Console.WriteLine(ControlChars.Cr + "Response Received.Trying to Close the response stream..")
' Release resources of response object
myWebResponse.Close()
Console.WriteLine(ControlChars.Cr + "Response Stream successfully closed")

Commenti

Il Close metodo pulisce le risorse usate da un WebResponse oggetto e chiude il flusso sottostante chiamando il Stream.Close metodo.The Close method cleans up the resources used by a WebResponse and closes the underlying stream by calling the Stream.Close method.

Nota

La risposta deve essere chiusa per evitare l'esaurimento delle risorse di sistema.The response must be closed to avoid running out of system resources. Il flusso di risposta può essere chiuso chiamando Stream.Close o Close.The response stream can be closed by calling Stream.Close or Close.

Nota

La WebResponse classe è una abstract classe.The WebResponse class is an abstract class. Il comportamento effettivo delle WebResponse istanze in fase di esecuzione è determinato dalla classe discendente restituita da. WebRequest.GetResponseThe actual behavior of WebResponse instances at run time is determined by the descendant class returned by WebRequest.GetResponse. Per ulteriori informazioni sui valori predefiniti e sulle eccezioni, vedere la documentazione relativa alle classi discendenti, ad HttpWebResponse esempio FileWebResponsee.For more information about default values and exceptions, please see the documentation for the descendant classes, such as HttpWebResponse and FileWebResponse.
