Beispiele
Im folgenden Codebeispiel wird ein ServicePoint-Objekt erstellt, das eine Verbindung mit dem URI-www.contoso.com
herstellt.
// This example shows how to use the ServicePoint and ServicePointManager classes.
// The ServicePointManager class uses the ServicePoint class to manage connections
// to a remote host. The networking classes reuse service points for all
// requests to a given URI. In fact, the same ServicePoint object
// is used to issue requests to Internet resources identified by the same
// scheme identifier (for example, HTTP) and host fragment (for example, www.contoso.com).
// This should improve your application performance.
// Reusing service points in this way can help improve application performance.

Hinweise
Vorsicht
WebRequest
, HttpWebRequest
, ServicePoint
und WebClient
sind veraltet, und Sie sollten sie nicht für die neue Entwicklung verwenden. Verwenden Sie stattdessen HttpClient.
Die ServicePoint Klasse verarbeitet Verbindungen mit einer Internetressource basierend auf den Hostinformationen, die im URI (Uniform Resource Identifier) der Ressource übergeben werden. Die anfängliche Verbindung mit der Ressource bestimmt die Informationen, die das ServicePoint-Objekt verwaltet, die dann von allen nachfolgenden Anforderungen an diese Ressource freigegeben wird.
ServicePoint Objekte werden von der ServicePointManager Klasse verwaltet und bei Bedarf durch die ServicePointManager.FindServicePoint-Methode erstellt. ServicePoint Objekte werden nie direkt erstellt, sondern immer von der ServicePointManager Klasse erstellt und verwaltet. Die maximale Anzahl von ServicePoint Objekten, die erstellt werden können, wird durch die ServicePointManager.MaxServicePoints-Eigenschaft festgelegt.
Jedes ServicePoint-Objekt behält seine Verbindung mit einer Internetressource bei, bis sie länger als die in der MaxIdleTime-Eigenschaft angegebene Zeit im Leerlauf war. Wenn ein ServicePoint den MaxIdleTime Wert überschreitet, kann es in eine andere Verbindung wiederverwendet werden. Der Standardwert von MaxIdleTime wird durch die ServicePointManager.MaxServicePointIdleTime-Eigenschaft festgelegt.
Wenn die ConnectionLeaseTimeout-Eigenschaft auf einen anderen Wert als -1 festgelegt wird und nach Ablauf der angegebenen Zeit eine aktive ServicePoint Verbindung geschlossen wird, nachdem sie die nächste Anforderung verwendet hat. Dies ist nützlich für Anwendungen, die keine aktiven Verbindungen erfordern, die unbegrenzt geöffnet werden, da sie standardmäßig vorhanden sind.
Anmerkung
Bei hohen Ladebedingungen laufen einige Anwendungen möglicherweise keine freien Threads im ThreadPool aus, was zu einer schlechten Systemleistung (z. B. hohe und variable Transaktionszeiten) führen kann.
Eigenschaften
Address |
Ruft den URI (Uniform Resource Identifier) des Servers ab, mit dem dieses ServicePoint-Objekt eine Verbindung herstellt. |
BindIPEndPointDelegate |
Gibt den Delegat an, der einem ServicePointein lokales IPEndPoint zuordnen soll. |
Certificate |
Ruft das Zertifikat ab, das für dieses ServicePoint -Objekt empfangen wurde. |
ClientCertificate |
Ruft das letzte Clientzertifikat ab, das an den Server gesendet wurde. |
ConnectionLeaseTimeout |
Dient zum Abrufen oder Festlegen der Anzahl von Millisekunden, nach denen eine aktive ServicePoint Verbindung geschlossen wird. |
ConnectionLimit |
Ruft die maximale Anzahl von Verbindungen ab, die für dieses ServicePoint -Objekt zulässig sind, oder legt diese fest. |
ConnectionName |
Ruft den Verbindungsnamen ab. |
CurrentConnections |
Ruft die Anzahl der geöffneten Verbindungen ab, die diesem ServicePoint -Objekt zugeordnet sind. |
Expect100Continue |
