有条件地设置标志
我的枚举定义为如下，
[Flags]
public enum Roles
{
[Descriptor("owner", "TheProficientLab representative")]
OWNER = 0,
[Descriptor("administrator", "Sets up users, questions, modules and reviews training and competency")]
ADMIN = 1,
[Descriptor("trainer", "Completes and submits training session with trainee")]
TRAINER = 2,
[Descriptor("trainee", "Completes training session with trainer")]
TRAINEE = 3,
[Descriptor("assessor", "Evaluates and submits competency assessments")]
ASSESSOR = 4,
[Descriptor("director or designee", "Approves training and competency")]
DIRECTOR = 5
}
然后是类
public common.constants.role.orles角色{get;放; }
我将如何将枚举设置为基于条件的多个标志
我正在寻找类似的东西。
if (something)
Item.Roles += Roles.ADMIN
if (something else)
Item.Roles += Roles.ASSESSOR
， 世界？
I have an enum defined as follows
[Flags]
public enum Roles
{
[Descriptor("owner", "TheProficientLab representative")]
OWNER = 0,
[Descriptor("administrator", "Sets up users, questions, modules and reviews training and competency")]
ADMIN = 1,
[Descriptor("trainer", "Completes and submits training session with trainee")]
TRAINER = 2,
[Descriptor("trainee", "Completes training session with trainer")]
TRAINEE = 3,
[Descriptor("assessor", "Evaluates and submits competency assessments")]
ASSESSOR = 4,
[Descriptor("director or designee", "Approves training and competency")]
DIRECTOR = 5
}
It is then a property in a class
public Common.Constants.Role.Roles Roles { get; set; }
How would I set that enum to multiple flags based on condition
Essentially I am looking for something like this
if (something)
Item.Roles += Roles.ADMIN
if (something else)
Item.Roles += Roles.ASSESSOR
Is there a += and -= equivalents in bitwise world?

iteg> itemroles＆amp; =〜prole.Admin要删除，并且值必须是每个幂的幂 docs
Per Idle_Mind's answer in the comments
Item.Roles |= Role.ADMINto addItemRoles &= ~Role.ADMINto removeand the values need to be powers of 2 per docs
