ASP.NET MVC特定角色5得到用户的好评 [英] ASP.NET MVC 5 Get users from specific Role

问题描述

这怎么可以显示所有用户列表中的特定角色。

How is it possible to show a List from all users in a specific role.

我附上IdentityRole模型我的看法与分配给它的管理员的角色。
到目前为止，我只可以得到用户标识。

I attach a IdentityRole model to my View with the 'Admin' role assigned to it. So far I only can get the UserId.

@model Microsoft.AspNet.Identity.EntityFramework.IdentityRole

@Html.DisplayNameFor(model => model.Name) // Shows 'Admin'

@foreach (var item in Model.Users)
{
    <tr>
        <td>
            @Html.DisplayFor(modelItem => item.UserId)
        </td>
    </tr>
}

一个可能的解决方案是创建在控制器的用户列表，并附这视图。问题是，我还需要从角色本身的数据。

A possible solution would be to create a List of the users in the controller and attach this to the View. The problem would be that I also need data from the Role itself.

推荐答案

如果您使用的是ASP.NET身份2：

If you are using ASP.NET Identity 2:

public ActionResult UserList(string roleName)
{
    var context = new ApplicationDbContext();
    var users = from u in context.Users
        where u.Roles.Any(r => r.Role.Name == roleName)
        select u;

    ViewBag.RoleName = roleName;
    return View(users);
}

和中查看：

@model Microsoft.AspNet.Identity.EntityFramework.IdentityUser // or ApplicationUser

@Html.DisplayNameFor(model => ViewBag.RoleName) // Shows 'Admin'

@foreach (var item in Model.Users)
{
    <tr>
        <td>
            @Html.DisplayFor(modelItem => item.Id)
        </td>
       <td>
            @Html.DisplayFor(modelItem => item.UserName)
        </td>
    </tr>
}
