欄位

DoNotUsePlusSign	32	辨別名稱不使用加號。
DoNotUseQuotes	64	辨別名稱不使用引號。
ForceUTF8Encoding	16384	強制辨別名稱將特定 X.500 金鑰編碼為 UTF-8 字串，而非可列印的 Unicode 字串。 如需詳細資訊，以及受影響的 X.500 金鑰清單，請參閱 X500NameFlags enumeration (X500NameFlags 列舉)。

備註

這個列舉會與 類別搭配 X500DistinguishedName 使用，以指出辨別名稱中包含的特殊字元。

在這個列舉中，有數個值互斥;只使用其中一個值來定義 X.500 辨別名稱的特殊特性。 例如，只指定其中 UseCommas一個、 UseNewLines 和 UseSemicolons 值。 您也會指定 UseT61Encoding 或 UseUTF8Encoding。
