Question

我在一个下拉框中有一个管理员列表，在一个面板上有一个用户列表，其中包含他们的名字和一个复选框。我的面板上有一个按钮，因此可以将用户分配给管理员。我想知道如何在控制器中为用户分配角色并不困难，但是这样做并不能100％地确定。这就是我所拥有的。

//我的观点

        <div class="row">
            @for(var i = 0; i < Model.lstUsers.Count(); i++)
            {
                <div class="col-md-4">
                    <div>
                        @Html.CheckBoxFor(u => Model.lstUsers[i].SelectedUsers)
                        <label>
                            @Html.DisplayFor(u => Model.lstUsers[i].Name)
                            @Html.HiddenFor(u => Model.lstUsers[i].UserId)
                            @Html.HiddenFor(u => Model.lstUsers[i].Name)
                        </label>
                    </div>
                </div>
            }
        </div>
        <br />

                     null, new { @class = "btn btn-danger" })
                </div>
            </div>
        </div>
    </div>      //Model                                                     public class AdminModel

    public List<UserModel> lstUsers { get; set; }

获取我拥有的用户列表，但我需要选中用户复选框并将其分配给管理员

Answer 1

这是我目前想出的。它尚未100％完成，但是我可以找到一个用户并将其分配给管理员，以确保可以与1个用户一起使用，我必须测试多个用户。我会对所做的任何输入或评论感兴趣。谢谢

    [HttpPost]
    [ValidateAntiForgeryToken]
    public ActionResult AssignAdmin(AssignRolesModel model)
    {
        try
        {
            if(model.lstUsers == null)
            {
                TempData["Error"] = "There are no Users to Assign Roles";
                model.lstUsers = UserList();
                model.lstAdmins = AdminList();
                return View(model);
            }

            var selectedUsersCount = (from user in model.lstUsers
                                      where user.SelectedUsers == true
                                      select user).Count();
            if(selectedUsersCount == 0)
            {
                TempData["Error"] = "You have not Selected any User to Assign Roles";
                model.lstAdmins = AdminList();
                model.lstUsers = UserList();
                return View(model);
            }

            if (ModelState.IsValid)
            {
                List<UserModel> users = new List<UserModel>();
                ApplicationUser au;
                var store = new UserStore<ApplicationUser>(context);
                var manager = new UserManager<ApplicationUser>(store);

                model.CreatedBy = 1;

                foreach(var u in model.lstUsers)
                {
                    if(u.SelectedUsers == true)
                    {
                        users.Add(u);
                    }
                }

                foreach(var u in users)
                {
                    au = context.Users.Where(x => x.Id.Equals(u.UserId,
                        StringComparison.CurrentCultureIgnoreCase)).FirstOrDefault();
                    manager.AddToRole(au.Id, "Admin");
                }

                TempData["Success"] = "Roles Assigned Successfully";
                return RedirectToAction("AssignAdmin");
            }
        }
        catch (Exception)
        {
            throw;
        }           

        return View();
    }
