Question

我使用教程here将用户数据库的主键从string更改为int，但是我在初始化Role Manager时遇到了困难。它曾经使用

进行初始化

var roleManager = new RoleManager<IdentityRole>(new RoleStore<IdentityRole>(context));

如何使用新数据创建角色管理器？

更新：我使用MVC 5和EF 6。

Answer 1

您的ApplicationRoleManager可能如下所示。因为你必须从customRole类而不是IdentityRole继承。

public class ApplicationRoleManager : RoleManager<CustomRole, int>
{
    public ApplicationRoleManager(IRoleStore<CustomRole, int> roleStore)
        : base(roleStore)
    {
    }

    public static ApplicationRoleManager Create(IdentityFactoryOptions<ApplicationRoleManager> options, IOwinContext context)
    {
        return new ApplicationRoleManager(new RoleStore<CustomRole, int, CustomUserRole>(context.Get<ApplicationDbContext>()));
    }
}

然后将以下代码添加到Startup.Auth.cs类（如果当前不存在。

）

app.CreatePerOwinContext<ApplicationRoleManager>(ApplicationRoleManager.Create);

然后，您可以创建和管理角色。

    var roleManager = HttpContext.GetOwinContext().Get<ApplicationRoleManager>();

    const string roleName = "Admin";

    //Create Role Admin if it does not exist
    var role = roleManager.FindByName(roleName);
    if (role == null)
    {
        role = new CustomRole();
        role.Id = 1; // this will be integer
        role.Name = roleName;

        var roleresult = roleManager.Create(role);
    }

希望这有帮助。

根据您的问题，我无法确定您是否使用相同的框架（MVC和EF）。

最近，我使用自定义ApplicationUsers＆amp; amp;创建了一个MVC + EF解决方案。 IdentityRoles。 ApplicationUser派生自“Microsoft.AspNet.Identity.EntityFramework.IdentityUser”。 ApplicationRoles无需更改即可实现。

我有以下课程：

// Configure the used in the application. RoleManager is defined in the ASP.NET Identity core assembly
    public class ApplicationRoleManager : RoleManager<IdentityRole>
    {
        public ApplicationRoleManager(IRoleStore<IdentityRole, string> roleStore)
            : base(roleStore)
        {
        }

        public static ApplicationRoleManager Create(IdentityFactoryOptions<ApplicationRoleManager> options, IOwinContext context)
        {
            return new ApplicationRoleManager(new RoleStore<IdentityRole>(context.Get<ApplicationDbContext>()));
        }
    }

在configuration.cs（迁移）中==＆gt;在'update-database'上将执行

    var roleStore = new RoleStore<IdentityRole>(context);
    var roleManager = new RoleManager<IdentityRole>(roleStore);
    var applicationRoleAdministrator = new IdentityRole("Administrator");
    if (!roleManager.RoleExists(applicationRoleAdministrator.Name))
    {
       roleManager.Create(applicationRoleAdministrator);
    }
// do some logic to find your applicationUserAdministrator
var applicationUserAdministrator = userManager.FindByName("Administrator");
userManager.AddToRole(applicationUserAdministrator.Id, applicationRoleAdministrator.Name);

使用startup.auth.cs与RoleManager的链接：

app.CreatePerOwinContext<ApplicationRoleManager>(ApplicationRoleManager.Create);

希望这有帮助。

    var roleManager = new RoleManager<CustomRole,int>(new RoleStore<CustomRole,int,CustomUserRole>(context));
    var UserManager = new UserManager<ApplicationUser,int>(new UserStore<ApplicationUser,CustomRole,int,CustomUserLogin,CustomUserRole,CustomUserClaim>(context));

   // In Startup iam creating first Admin Role and creating a default Admin User     
    if (!roleManager.RoleExists("Admin")){
    //first we create Admin rool   
        var role = new CustomRole();
        role.Name = "Admin";
        roleManager.Create(role);
    }

    ////Here we create a Admin super user who will maintain the website     
    if (UserManager.FindByName("Admin") == null){
        var user = new ApplicationUser() { UserName = "Admin" };
        string userPWD = "adminadmin";
        var chkUser = UserManager.Create(user, userPWD);
        if (chkUser.Succeeded){
            var result1 = UserManager.AddToRole(user.Id, "Admin")
            ;
        }
    }

使用自定义角色在ASP.NET标识中初始化RoleManager
