我正在使用@model IEnumerable<WebApplication.Models.ApplicationUser>
查看
@foreach (var user in Model)
{
<tr>
<td>
@foreach(var role in user.Roles){
role.Name; //invalid
role.RoleId; //valid
role.UserId; //valid
}
</td>
</tr>
}
模型
public class ApplicationUser : IdentityUser
{
[Required]
public string FirstName { get; set; }
[Required]
public string LastName { get; set; }
public async Task<ClaimsIdentity> GenerateUserIdentityAsync(UserManager<ApplicationUser> manager)
{
// Note the authenticationType must match the one defined in CookieAuthenticationOptions.AuthenticationType
var userIdentity = await manager.CreateIdentityAsync(this, DefaultAuthenticationTypes.ApplicationCookie);
// Add custom user claims here
return userIdentity;
}
}
我可以从这个角色获得RoleID和UserId但是如何获得Role.Name?
IdentityUser [来自元数据]

我能找到在剃须刀布局视图中获取角色的唯一方法是从请求中获取UserManager
。
Razor查看:
@using Microsoft.AspNet.Identity
@using Microsoft.AspNet.Identity.Owin;
@if (Request.IsAuthenticated) {
var userManager = Request.GetOwinContext().GetUserManager<ApplicationUserManager>();
var userRoles = userManager.GetRoles(User.Identity.GetUserId());
var role = userRoles[0];
}

如果IdentityUserRole
的角色类型为Microsoft.AspNet.Identity.EntityFramework
,则您无权访问角色名称。您可以从IdentityUserRole<TKey>
实现自己的角色并设置角色名称或直接通过查询EF存储来加载角色。

作为查理答案的延伸,您可以通过获取Roles
集合并将其传递到视图模型中来实现此目的。
@foreach (var user in Model)
{
<tr>
<td>
@foreach(var role in user.Roles){
Model.Roles.First(x=>x.RoleID == role.RoleID).Name;
role.RoleId; //valid
role.UserId; //valid
}
</td>
</tr>
}
