Question

当我_userManager.FindByNameAsync(email)时，我能够检索到正确的用户记录。但是，我的角色字段的计数为0.如果我查看数据库，实际上有与我的用户ID相关联的角色。

我在.NET 2.0上

在我的startup.cs中：

services.AddIdentity<ApplicationUser, ApplicationRole>

我的applicationRole：

public class ApplicationRole : IdentityRole
{
    // public virtual ICollection<ApplicationUser> Users { get; } = new List<ApplicationUser>();

    public ApplicationRole(){}
    public ApplicationRole(string roleName) : base(roleName) {}
    public virtual ICollection<IdentityUserRole<string>> Users { get; set; }

    public virtual ICollection<IdentityRoleClaim<string>> Claims { get; set; }
}

我的应用程序用户：

public class ApplicationUser : IdentityUser
{
    [InverseProperty("User")]
    public virtual Player Player { get; set; }

    public List<ApplicationUserClubs> Clubs { get; set; }
    public int? CustomerProfileId { get; set; }
    /// <summary>
    /// Navigation property for the roles this user belongs to.
    /// </summary>
    public virtual ICollection<IdentityUserRole<string>> Roles { get; } = new List<IdentityUserRole<string>>();
}

我的查询是：

ApplicationUser user = await _userManager.FindByNameAsync(model.Email);

在我迁移到.NET 2.0之前，这曾经很好用。

编辑：

foreach (IdentityRole role in allRoles)
{
    bool isUserInRole = role.Users.FirstOrDefault(x => x.Id == u.Id) != null;
    userInRoles.Add(item: new AdminUserRoleViewModel
    {
        Id = role.Id,
        Name = role.Name,
        IsUserInRole = isUserInRole
    });
}

我尝试做Role.Users时遇到异常。例外情况说：

'IdentityRole'不包含'Users'和no的定义扩展方法'用户'接受类型的第一个参数可以找到'IdentityRole'（你是否错过了使用指令或者装配参考？

那时我决定使用自定义类ApplicationRole扩展IdentityRole

这里也是我的上下文文件：

protected override void OnModelCreating(ModelBuilder builder)
{
    base.OnModelCreating(builder);

    builder.Entity<IdentityUser>().ToTable("AspNetUsers")
        .HasKey(x => x.Id);

    builder.Entity<IdentityRole>().ToTable("AspNetRoles")
        .HasKey(x => x.Id);

    builder.Entity<IdentityUserRole<string>>().ToTable("AspNetUserRoles")
        .HasKey(x => new { x.UserId, x.RoleId });

    builder.Entity<IdentityUserClaim<string>>().ToTable("AspNetUserClaims")
        .HasKey(x => x.Id);

    builder.Entity<IdentityUserLogin<string>>().ToTable("AspNetUserLogins")
        .HasKey(x => new { x.UserId, x.ProviderKey });

    builder.Entity<IdentityUserToken<string>>().ToTable("AspNetUserTokens")
        .HasKey(x => new { x.UserId, x.LoginProvider, x.Name });

    builder.Entity<IdentityRoleClaim<string>>().ToTable("AspNetRoleClaims")
        .HasKey(x => x.Id);

    builder.Entity<ApplicationUserToken>().ToTable("UserTokens")
    .HasKey(x => x.Id);
}

用户中的角色为空
