Ausnahmen

Hinweise

Wenn WebPermissionAttribute auf die Klasse angewendet wird, gibt diese Eigenschaft die für die Verwendung in dieser Klasse akzeptierte URI-Zeichenfolge an. Diese Berechtigung wird angewendet, wenn das Sicherheitssystem CreatePermission aufruft. Diese Eigenschaft kann nur einmal festgelegt werden.

Beispiel

Im folgenden Beispiel wird veranschaulicht, wie WebPermissionAttribute zum Angeben einer zulässigen Accept-Zeichenfolge verwendet wird.

 ' Deny access to a specific resource by setting the Accept property.

<WebPermission(SecurityAction.Deny, Accept := "https://www.contoso.com/Private.htm")>  _
   Public Shared Sub CheckAcceptPermission(uriToCheck As String)
   Dim permissionToCheck As New WebPermission()
   permissionToCheck.AddPermission(NetworkAccess.Accept, uriToCheck)
   permissionToCheck.Demand()
End Sub 'CheckAcceptPermission


Public Shared Sub demoDenySite()
   ' Pass the security check when accessing allowed resources.
   CheckAcceptPermission("https://www.contoso.com/Public.htm")
   Console.WriteLine("Public page has passed Accept permission check")
