DoNotUsePlusSign | 32 | The distinguished name does not use the plus sign. |
DoNotUseQuotes | 64 | The distinguished name does not use quotation marks. |

Remarks
This enumeration is used with the X500DistinguishedName class to indicate special characters contained in the distinguished name.
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. For example, specify only one of the UseCommas
, UseNewLines
, and UseSemicolons
values. You would also specify either UseT61Encoding
or UseUTF8Encoding
.
