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)。 |
None | 0 | 辨別名稱沒有特殊的特性。 |
Reversed | 1 | 辨別名稱會反轉。 |
UseCommas | 128 | 辨別名稱使用逗號。 |
UseNewLines | 256 | 辨別名稱使用新行字元。 |
UseSemicolons | 16 | 辨別名稱使用分號。 |
UseT61Encoding | 8192 | 辨別名稱使用 T61 編碼。 |
UseUTF8Encoding | 4096 | 辨別名稱使用 UTF8 編碼,而不是 Unicode 字元編碼。 |

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
。
