将所有用户及其角色获取到 table asp.net mvc

Question

我正在尝试弄清楚如何让所有用户和他们的角色组织得井井有条 table，看到了许多不同的方法，但 none 对我有用。至少我已经掌握了一点...有人可以帮助我吗？

通过这段代码我得到了所有的角色：

        var context = new ApplicationDbContext();
        var roleStore = new RoleStore<IdentityRole>(context);
        var roleManager = new RoleManager<IdentityRole>(roleStore);
        var roles = (from r in roleManager.Roles select r.Name).ToList();
        ViewBag.Roles = roles.ToList();

通过这段代码，我获得了所有注册用户：

        var context = new ApplicationDbContext();
        var userStore = new UserStore<ApplicationUser>(context);
        var userManager = new UserManager<ApplicationUser>(userStore);
        var users = (from u in userManager.Users select u.UserName).ToList();
        ViewBag.Users = users.ToList();

最后用这段代码我得到了所有用户的 id

        var context = new ApplicationDbContext();
        var user = (from u in userManager.Users select u.Id).ToList();
        ViewBag.id = user.ToList();

但是我如何获得所有用户及其角色？我真的想不通

Answer 1

我相信您正在使用 AspNetUserRoles table 来管理用户和角色。您可以使用 EF 和 Linq -

在网格中优化 User/Role 的显示

[GridAction]
public ActionResult _GetUsers()

{
    var users = from user in xcsnEntities.Users
                select new
                {
                    Role = user.Roles.FirstOrDefault().RoleName,
                    IsApproved = user.Membership.IsApproved,
                    Email = user.Membership.Email,
                    UserName = user.UserName
                };

    return View(new GridModel(users));
}

这是获取用户列表（带有用户名）和相关角色列表的一个选项。

控制器：

public ActionResult GetRoles()
        {
            var userRoles = new List<RolesViewModel>();
            var context = new ApplicationDbContext();
            var userStore = new UserStore<ApplicationUser>(context);
            var userManager = new UserManager<ApplicationUser>(userStore);

            //Get all the usernames
            foreach (var user in userStore.Users)
            {
                var r = new RolesViewModel
                {
                    UserName = user.UserName
                };
                userRoles.Add(r);
            }
            //Get all the Roles for our users
            foreach (var user in userRoles)
            {
                user.RoleNames = userManager.GetRoles(userStore.Users.First(s=>s.UserName==user.UserName).Id);
            }

            return View(userRoles);
        }

ViewModel

public class RolesViewModel
{
    public IEnumerable<string> RoleNames { get; set; }
    public string UserName { get; set; }
}

视图：简单一个

@model IEnumerable<Whosebug.Models.RolesViewModel>
@foreach (var user in Model.ToList())
{
    <div> @user.UserName -- </div>
    foreach (var role in user.RoleNames)
    {
        <div> @role </div>
    }
    <br />
}
