X500DistinguishedNameFlags 枚举


指定 X.500 标识名的特性。Specifies characteristics of the X.500 distinguished name.

此枚举有一个 FlagsAttribute 属性,允许按位组合成员值。

public enum class X500DistinguishedNameFlags
public enum X500DistinguishedNameFlags
type X500DistinguishedNameFlags = 
Public Enum X500DistinguishedNameFlags


DoNotUsePlusSign 32

标识名不使用加号。The distinguished name does not use the plus sign.

DoNotUseQuotes 64

标识名不使用引号。The distinguished name does not use quotation marks.

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。Forces the distinguished name to encode specific X.500 keys as UTF-8 strings rather than printable Unicode strings. 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)。For more information and the list of X.500 keys affected, see the X500NameFlags enumeration.

None 0

标识名没有特殊特性。The distinguished name has no special characteristics.

Reversed 1

反转标识名。The distinguished name is reversed.

UseCommas 128

标识名使用逗号。The distinguished name uses commas.

UseNewLines 256

标识名使用新行字符。The distinguished name uses the new line character.

UseSemicolons 16

标识名使用分号。The distinguished name uses semicolons.

UseT61Encoding 8192

标识名使用 T61 编码。The distinguished name uses T61 encoding.

UseUTF8Encoding 4096

可分辨名称使用 UTF8 编码而不是 Unicode 字符编码。The distinguished name uses UTF8 encoding instead of Unicode character encoding.

此枚举与X500DistinguishedName类一起使用, 以指示可分辨名称中包含的特殊字符。This enumeration is used with the X500DistinguishedName class to indicate special characters contained in the distinguished name.

此枚举中有几个值互相排斥;仅使用这些值中的一个值来定义 X 的可分辨名称的特殊特性。Several values are mutually exclusive in this enumeration; use only one of these values to define the special characteristics of an X.500 distinguished name. 例如, 仅指定UseCommasUseNewLinesUseSemicolons值中的一个。For example, specify only one of the UseCommas, UseNewLines , and UseSemicolons values. 你还可以指定UseT61Encoding或。 UseUTF8EncodingYou would also specify either UseT61Encoding or UseUTF8Encoding.
