asp.net - 如何在不对其进行硬编码的情况下使用角色 (asp.net)？

Question

创建/删除角色时，我不想修改代码。

if (HttpContext.Current.User.IsInRole("Super Admin") ||
    HttpContext.Current.User.IsInRole("Admin") ||
    HttpContext.Current.User.IsInRole("Support"))
{
    if (HttpContext.Current.User.IsInRole("Admin"))
    {
        ListBox1.DataSource = Roles.GetAllRoles().Except(
            new[] { "Super Admin" });

    }
    if (HttpContext.Current.User.IsInRole("Support"))
    {
        ListBox1.DataSource = Roles.GetAllRoles().Except(
            new[] { "Super Admin", "Admin" });
    }
    fillDropDownCustomers();
}

将这些值放在静态类中:

public static class MyRoles
{
    public const string Admin = "Admin";
    public const string SuperAdmin = "Super Admin";
    public const string Support = "Support";
}

现在你可以像这样重用它们:

if (HttpContext.Current.User.IsInRole(MyRoles.SuperAdmin) ||
    HttpContext.Current.User.IsInRole(MyRoles.Admin) ||
    HttpContext.Current.User.IsInRole(MyRoles.Support))
{
