列表asp.net标识中用户的角色名称

Question

I am trying to list all my users in view. I also want to list roles which is belong to user. But i just can get id of role for user. But I want to list all my role names not role id. How can i do that? Here is my code:

public async Task<ActionResult> Index()
{
    var user = await _context.Users.Include(x=> x.Roles).ToListAsync();
    ViewBag.Roles = await _context.Roles.ToListAsync();
    return View(user);
}

In view

@model List<Projectname.Web.Models.ApplicationUser>

@foreach (var c in Model) 
{
    <tr>
        <td>@c.UserName</td>
        <td>@c.Email</td>
        <td>@c.LockoutEnabled</td>
        @foreach (var role in c.Roles)
        {
            <td>@role.RoleId</td>
        }
    </tr>
}

ps I am using Asp.net identity

If you are trying to get the roles of each user, Aren't you supposed to just access it from your var user ? In other words, you just need to use user.Roles

Since you already fetched a list of user under the variable named user ... Well first of all if you are saving a list, array or whatever form of collection, you have to name your variable in plural form. In your case it should look like:

var users = await _context.Users.Include(x=> x.Roles).ToListAsync();

Now back to the main point... Now that you have fetched the users with Include of Roles, you just it would look like this, assuming that your Model is the collection of users.

@foreach (var user in Model) 
{
    <tr>
        <td>@user.UserName</td>
        <td>@user.Email</td>
        <td>@user.LockoutEnabled</td>
        @foreach (var role in user.Roles)
        {
            <td>@role.Id</td>
            <td>@role.Name</td>
        }
    </tr>
}
