构造从实体相似的对象模型 [英] Constructor for object model similar from entity

问题描述

我想我最好遵循一些MVC准则和现在，我已经创建了我从我有一个实体需要领域的典范。我创建了以下模型类：

I'm trying my best to follow some MVC guidelines and for now, I have created a model with the fields I need from an entity I have. I have created the following Model class:

    public class PersonStyle
       {
            public string Name  { get; set; }
            public int? Age     { get; set; }
            public string City  { get; set; }
            public string Style { get; set; }
        }

我的实体是sometihng这样的：

My Entity is sometihng like:

     public class PersonOE
        {
            public string Name  { get; set; }
            public int? Age     { get; set; }
            public string City  { get; set; }
        }

我试着去建立以下的构造：

Im trying to build a constructor for the following:

  PersonON personBus = new personBus();
  List<PersonStyle> personStyleList = new List<PersonStyle>(personBus.getPeople()); //getPeople(); returns a PersonOE list

对于这一切，我需要关于如何创建 PersonStyle 构造，将放在空到从 PersonOE唯一不同的变量建议模式。

For this all, I need suggestions on how to create the PersonStyle constructor that will put "null" into the only different variable from the PersonOE model.

推荐答案

所有你需要做的是使用LINQ生成您的属性。虽然，将您样式到他们每个人可以得到一个有点难以对付，但你没有给他们来自何处的任何输入。这是从你的数据转换为模拟对象的一个​​快速简便的方法。

All you need to do is use LINQ to generate your properties. Though, adding your Style to each of them could get a little harder to deal with, but you haven't given any input on where they're coming from. This is a quick and easy way to convert from your data to model objects.

List<PersonStyle> personStyleList = personBus.GetPeople()
                                        .Select(p => new PersonStyle {
                                            Name = p.Name,
                                            Age = p.Age,
                                            City = p.City
                                        });
