指定 X.500 可分辨名称的特性。
此枚举支持其成员值的按位组合。
public enum class X500DistinguishedNameFlags
[System.Flags]
public enum X500DistinguishedNameFlags
[<System.Flags>]
type X500DistinguishedNameFlags =
Public Enum X500DistinguishedNameFlags
- 继承
- 属性
字段
DoNotUsePlusSign | 32 | 可分辨名称不使用加号。 |
DoNotUseQuotes | 64 | 可分辨名称不使用引号。 |
ForceUTF8Encoding | 16384 | 强制可分辨名称将特定 X.500 密钥编码为 UTF-8 字符串而不是可打印的 Unicode 字符串。 有关受影响的 X.500 密钥的详细信息和列表,请参阅 X500NameFlags enumeration(X500NameFlags 枚举)。 |
None | 0 | 可分辨名称没有特殊特性。 |
Reversed | 1 | 反转可分辨名称。 |
UseCommas | 128 | 可分辨名称使用逗号。 |
UseNewLines | 256 | 可分辨名称使用新行字符。 |
UseSemicolons | 16 | 可分辨名称使用分号。 |
UseT61Encoding | 8192 | 可分辨名称使用 T61 编码。 |
UseUTF8Encoding | 4096 | 可分辨名称使用 UTF8 编码而不是 Unicode 字符编码。 |

注解
此枚举与 类一起使用, X500DistinguishedName 以指示可分辨名称中包含的特殊字符。
在此枚举中,多个值互斥;仅使用其中一个值来定义 X.500 可分辨名称的特殊特征。 例如,仅指定 、 UseNewLines
和 UseSemicolons
值之UseCommas
一。 还可以指定 UseT61Encoding
或 UseUTF8Encoding
。
