Keterangan

Enumerasi ini digunakan dengan X500DistinguishedName kelas untuk menunjukkan karakter khusus yang terkandung dalam nama khusus.

Beberapa nilai saling eksklusif dalam enumerasi ini; gunakan hanya salah satu nilai ini untuk menentukan karakteristik khusus dari nama khusus X.500. Misalnya, tentukan hanya salah UseCommassatu nilai , UseNewLines , dan UseSemicolons . Anda juga akan menentukan atau UseT61EncodingUseUTF8Encoding.
