Kommentarer

Egenskapen LogonUserIdentity visar egenskaperna och metoderna för objektet WindowsIdentity för den för närvarande anslutna användaren till Microsoft Internet Information Services (IIS). Instansen av klassen WindowsIdentity som exponeras av LogonUserIdentity spårar IIS-begärandetoken och ger enkel åtkomst till denna token för den aktuella HTTP-begäran som bearbetas i ASP.NET. En instans av WindowsIdentity klassen skapas automatiskt så att den inte behöver konstrueras för att få åtkomst till dess metoder och egenskaper.
