在Asp.Net Mvc 6中，public Boolean isAdmin
public Boolean isAdminUser()
{
if (User.Identity.IsAuthenticated)
{
var user = User.Identity;
ApplicationDbContext context = new ApplicationDbContext();
var UserManager = new UserManager<ApplicationUser>(new UserStore<ApplicationUser>(context));
var s = UserManager.GetRoles(user.GetUserId());
if (s[0].ToString() == "Admin")
{
return true;
}
else
{
return false;
}
}
return false;
}
我的问题在Asp.Net Mvc 6中， GetRoles和GetUserId不存在，在MVC 5中有两个这样的，由于汇编版本： Microsoft.AspNet.Identity.Core 。 有人可以帮我纠正这个问题吗？
正如上面提到的代码，我执行我遇到如下：

我用新方法修复IsAdminUser，代码没有错误，如果有人知道如何修复它，我仍然没有很好的结果。 请注意谢谢。
您可以检查用户是否具有以下代码的角色。
if(User.IsInRole("Admin"))
{
return true;
}
else
{
return false;
}
