Keterangan

Properti LogonUserIdentity mengekspos properti dan metode WindowsIdentity objek untuk pengguna yang saat ini terhubung ke Microsoft Internet Information Services (IIS). Instans WindowsIdentity kelas yang diekspos oleh LogonUserIdentity melacak token permintaan IIS dan menyediakan akses mudah ke token ini untuk permintaan HTTP saat ini yang sedang diproses di dalam ASP.NET. Instans WindowsIdentity kelas dibuat secara otomatis sehingga tidak perlu dibangun untuk mendapatkan akses ke metode dan propertinya.
