Question

我正在调用一个似乎无法正常工作的linq语句：

我的客户端型号：

public class Client
{

    [UIHint("Hidden")]
    public int ClientId { get; set; }

    [UIHint("Hidden")]
    public int UserProfileId { get; set; }

    public int Age { get; set; }

    [UIHint("Hidden")]
    public int GenderId { get; set; }
    public string GenderDescription { get; set; }

    [UIHint("Hidden")]
    public int SettingId { get; set; }

    public virtual Gender Gender { get; set; }
    public virtual Setting Setting { get; set; }
    public virtual UserProfile UserProfile { get; set; }
}

我的Linq电话：

var clients = db.Clients.Include(c => c.Gender).Include(c => c.Setting).Include(c => c.UserProfile).OrderBy(c => c.ClientId);

这将使用GenderId和SettingId基于适当的信息填充Gender和Setting字段，但UserProfile不会。有没有合理的解释，还是我需要不停地靠在桌子上？

Answer 1

我遇到的问题是，当我创建UserProfile模型时，我使用了UserId而不是UserProfileId。该框架一直在寻找一个不存在的Id。

正确的模型应如下所示：

public class UserProfile
{
    public UserProfile()
    {
        this.Casefiles = new HashSet<Casefile>();
    }

    [Display(Name="Author")]
    public string FullName
    {
        get { return LastName + ", " + FirstName; }
    }

    [Key]
    [DatabaseGeneratedAttribute(DatabaseGeneratedOption.Identity)]
    public int UserProfileId { get; set; }
    public string UserName { get; set; }
    public string FirstName { get; set; }
    public string LastName { get; set; }

    [EmailAddress]
    public string EmailAddress { get; set; }

    // UserInRole Level
    public string Role { get; set; }

    [Display(Name = "Request Account Uplevel to Contributor")]
    public bool RequestUplevel { get; set; }

    public virtual ICollection<Casefile> Casefiles { get; set; }

}

当您拨打电话时这样：

var clients = db.Clients.Include(c => c.Gender)
                        .Include(c => c.Setting)
                        .Include(c => c.UserProfile)
                        .OrderBy(c => c.ClientId)
                        .Where(u => u.UserProfileId == WebSecurity.CurrentUserId);

这将返回客户端模型中的每个虚拟调用。

Statement不会返回所有实体
