Namespace: System.Net
Assembly: System (in system.dll)

'Declaration
Public ReadOnly Property ServicePoint As ServicePoint
'Usage
Dim instance As HttpWebRequest
Dim value As ServicePoint

value = instance.ServicePoint

/** @property */
public ServicePoint get_ServicePoint ()

public function get ServicePoint () : ServicePoint

Property Value

A ServicePoint that represents the network connection to the Internet resource.

The ServicePoint.Address property may be different from HttpWebRequest.Address if the request is redirected.

Windows Mobile for Pocket PC, Windows Mobile for Smartphone, Windows CE Platform Note: This property is a null reference (Nothing in Visual Basic) until the request is sent because of the additional network transmission required.
