Question

我在填补用户角色时遇到问题，我找不到解决方案。我有用户角色列表，但我不知道如何将其发送到模型。我的代码：

ApplicationUser

    namespace WebApp.Models
{
    public class ApplicationUser : IdentityUser
    {
        public ApplicationUser() : base() { }

        public string FirstName { get; set; }
        public string LastName { get; set; }

        public IEnumerable<ApplicationRole> UserRoles { get; set; }

    }
}

ApplicationRole

namespace WebApp.Models
    {
        public class ApplicationRole : IdentityRole
        {
            public ApplicationRole() : base() { }

            public ApplicationRole(string roleName) : base(roleName) { }

            public ApplicationRole(string roleName, string description, DateTime creationDate) : base(roleName)
            {
                this.Description = description;
                this.CreationDate = creationDate;
            }

            public string Description { get; set; }
            public DateTime CreationDate { get; set; }

        }
    }

AdminController

 public async Task<IActionResult> UserList(ApplicationUser ApplicationUser)
        {
            var users = await _userManager.Users.ToListAsync();

            foreach (var v in users)
            {
                var userId = await _userManager.GetUserIdAsync(v);
                var user = _context.Users.Where(u => u.Id == userId).FirstOrDefault();

                user.UserRoles = _userManager.GetRolesAsync(v);

                _context.SaveChanges();
            }

            var usersList = _context.Users.ToList();

            return await Task.Run(() => View(usersList));
        }

user.UserRoles = _userManager.GetRolesAsync（v）;

导致错误

// EDIT错误是由于缺少asynch引起的，但现在的错误是

如何转换数据以填充UserRoles？
