在不使用实体框架的情况下，仅将来自不同模型的必需字段/属性调用到 asp.net mvc 5 中的视图模型中

Question

我有两个不同的模型。 UserPersonalDetail和UserEducationalDetails

我想将上述两个模型中的一些字段填充到名为UserViewModel视图模型中。

我试过了，但我从两个模型中获取了所有字段。

public class UserEducationalDetails
{
    public Boolean Undergraduate { get; set; }

    public Boolean PostGraduate { get; set; }

    public String CollegeName { get; set; }

    public String SchoolName { get; set; }
}

public class UserPersonalDetail
{
    public String  FullName {get; set;}

    public string  FirstName { get; set; }

    public string LastName { get; set; }

    public string FatherName { get; set; }

    public string placeofBirth { get; set; }

    public string MarriedStatus { get; set; }
}

我希望用户视图模型应该是

public class UserViewModel
{
    //Want to view the only following fields from UserPersonalDetails and UserEducationalDetails Model
    //From UserEducationalDetails Model

    public UserEducationalDetails CollegeName { get; set; }

    public UserEducationalDetails SchoolName { get; set; }

    //From UserEducationalDetails Model

    public UserPersonalDetail FullName {get; set;}

    public UserPersonalDetail MarriedStatus { get; set; }

}

Answer 1

您误解了模型类的工作方式。 例如，当你定义这个时：

public class UserViewModel
{
    public UserEducationalDetails CollegeName { get; set; }
}

这并不意味着UserEducationalDetails取自UserEducationalDetails模型，这意味着它是一个 UserEducationalDetails 模型。 这显然不是你想要的。 您要做的是在构造UserViewModel时读取属性，如下所示：

public class UserViewModel
{
    // Types reflect the types used in the models
    public string CollegeName { get; private set; }

    public string SchoolName { get; private set; }

    public string FullName {get; private set;}

    public string MarriedStatus { get; private set; }

    public UserViewModel(UserEducationalDetails ued, UserPersonalDetails upd)
    {
        // Copy the properties that are relevant to this object
        CollegeName = ued.CollegeName;
        SchoolName = ued.SchoolName;
        FullName = upd.FullName;
        MarriedStatus = upd.MarriedStatus;
    }
}
