MVC C# 中复选框的枚举值

Question

我正在研究一种功能角色和权限。 我想在这方面做出最好的工作。 我有些怀疑。 我的枚举 Class 是

public enum Roles
    {
        UserCreate = 1,
        UserEdit = 2,
        UserDelete = 3,
        UserAssign = 4,
        UserView = 5,

        TeamsCreate = 6,
        TeamsEdit = 7,
        TeamsDelete = 8,
        TeamsAssign = 9,
        TeamsView = 10,
    }

我的数据是

public RolesViewData : MasterViewData
    {
       Public List<Roles> Roles {Get;Set;}
    }

视图是

<div class="col-md-8">
  <label>Permissions: <span>*</span></label>
   <input id="chkCreate" name="chkCreate" type="checkbox"/> User Create 
   <input id="chkEdit" name="chkEdit" type="checkbox"/> User  Edit
   <input id="chkDelete" name="chkDelete" type="checkbox"/> User Delete
   <input id="chkAssign " name="chkAssign" type="checkbox"/> User Assign 
    <input id="chkView" name="chkView" type="checkbox"/> User View

 <input id="chkTDelete" name="chkTDelete" type="checkbox"/> Team Create 
   <input id="chkTEdit" name="chkTEdit" type="checkbox"/> Team Edit
   <input id="chkTDelete" name="chkTDelete" type="checkbox"/> Team Delete
   <input id="chkTAssign " name="chkTAssign " type="checkbox"/> Team Assign 
    <input id="chkTView" name="chkTView" type="checkbox"/> Team View
</div>

那么我们需要哪个复选框？ 枚举？ 你能建议我最好的方法吗

使用Description命名枚举：

  public enum Roles
    {
        [Description("User Create")]
        UserCreate = 1, 
        [Description("...")]
        UserEdit = 2,
        [Description("...")]
        UserDelete = 3,
        [Description("...")]
        UserAssign = 4,
        [Description("...")]
        UserView = 5, 
        [Description("...")]
        TeamsCreate = 6,
        [Description("...")]
        TeamsEdit = 7,
        [Description("...")]
        TeamsDelete = 8,
        [Description("...")]
        TeamsAssign = 9,
        [Description("...")]
        TeamsView = 10,
    }

使用 extionsion 方法获取名称：

  public static string GetDescription<T>(this T e) where T : IConvertible
        {
            return
                e.GetType()
                    .GetMember(e.ToString())
                    .FirstOrDefault()
                    ?.GetCustomAttribute<DescriptionAttribute>()
                    ?.Description ?? e.ToString();
        }

然后使用 forach 查看：

@foreach (var item in Enum.GetValues<UserRole>())
{
    <input id="@item" name="@item" type="checkbox" value="@item" />
    @item.GetDescription()
}
