Parametreler

  • userName
    Tür: System.String
    Rapor sunucusu erişim isteyen kullanıcının adı.
  • userToken
    Tür: System.IntPtr
    Bir kullanıcı hesabı simgesi.Bu belirteç, öncelikle Windows kimlik doğrulaması için Kimlik Yönetimi'nın bir Microsoft Windows hesabı için bir tanıtıcı olarak rapor sunucusu tarafından kullanılır.
  • secDesc
    Tür: array<System.Byte[]
    öğe için güvenlik tanımlayıcısı.

Dönüş Değeri

Tür: System.Boolean
Döndürür doğru şu anda kimliği doğrulanmış kullanıcının erişim sağlanan işlemi ve güvenlik tanımlayıcısını temel alan öğe verilir.
