ASP.NET MVC的複雜模型驗證

Question

我有一個複雜的模型

public class ComplexModel 
{ 

    public UserModel userModel; 

    public ExtraInfoModel extraModel; 
} 

其中

的usermodel可能必填字段

爲：

public class UserModel 
{ 

    [Required] 
    public string email; 
} 

我怎麼驗證ComplexModel以確保其成員模型上的數據註釋正在被帶入Compl中的帳戶exModel驗證？

謝謝。

更新：

這是我的確切場景。當我在ManageProfileModel的控制器操作中調用ModelState.IsValid時，無論是否設置了GeneralInfoModel的ListModelRequired成員的「SelectedValue」，模型狀態都是有效的。

public class ManageProfileModel 
{ 
    [Required(ErrorMessage="Experience is required")] 
    public int LevelOfExperienceTypeID { get; set; } 
    public GeneralInfoModel GeneralInfoModel { get; set; } 
} 

public class GeneralInfoModel 
{ 
    [Required] 
    [DisplayName("Profile Headline")] 
    public string ProfileName { get; set; } 

    [DisplayName("Signature")] 
    public string Signature { get; set; } 

    [Required] 
    public ListModelRequired LevelOfExperience { get; set; } 
} 

public class ListModel 
{ 
    public ListModel() 
    { 
    } 

    public ListModel(string name) 
    { 
     this.Name = name; 
    } 

    public ListModel(string name, string selectedValue):this(name) 
    { 
     this.SelectedValue = selectedValue; 
    } 

    public ListModel(string name, IEnumerable<SelectListItem> members):this(name) 
    { 
     this.Members = members; 
    } 

    public ListModel(string name, IEnumerable<SelectListItem> members, string selectedValue) 
     : this(name, members) 
    { 
     this.SelectedValue = selectedValue; 
    } 

    public IEnumerable<SelectListItem> Members { get; set; } 

    public string Name { get; set; } 

    public virtual string SelectedValue { get; set; } 

    public string Label { get; set; } 
} 

public class ListModelRequired : ListModel 
{ 
    [Required] 
    public override string SelectedValue { get; set; } 

    public ListModelRequired():base() 
    { 
    } 

    public ListModelRequired(string name):base(name) 
    { 
    } 

    public ListModelRequired(string name, string selectedValue):base(name,selectedValue) 
    { 
    } 

    public ListModelRequired(string name, IEnumerable<SelectListItem> members) 
     : base(name, members) 
    { 
    } 

    public ListModelRequired(string name, IEnumerable<SelectListItem> members, string selectedValue) 
     : base(name, members,selectedValue) 
    { 
    } 
}

我認爲默認模型聯編程序得到這個權限，驗證使用數據註釋的子模型。你真的有什麼問題嗎？例如，我有類似的東西：

public class OnlineDonationModel 
{ 
    [Required] 
    public decimal? Amount { get; set; } 

    public ContactModel Contact { get; set; } 
} 

public class ContactModel 
{ 
    [Required] 
    public string FirstName { get; set; } 

    [Required] 
    public string LastName { get; set; } 

    [Required] 
    public string Address { get; set; } 

    ... 
}
