asp.net-mvc – ASP.NET MVC帖子模型的示例？

当操作返回视图时,它也必须为它提供模型.但是,视图不必使用相同的模型.实际上,可以使用包含扩展数据的不同模型强类型化视图,例如,它可以将导航属性绑定到DB表中的外部键;如果是这种情况,从POST模型映射到视图模型的逻辑将包含在POST操作中.

public class MyGetModel
{
    string FullName;
    List<MyGetModel> SuggestedFriends;
}

public class MyPostModel
{
    string FirstName;
    string LastName;
}

//GET: /Customer/Create
public ActionResult Create()
{
    MyGetModel myName = new MyGetModel();
    myName.FullName = "John Doe"; // Or fetch it from the DB
    myName.SuggestedFriends = new List<MyGetModel>; // For example - from people select name where name != myName.FullName
    Model = myName;
    return View();
}

//POST: /Customer/Create
[HttpPost]
public ActionResult Create(MyPostModel newName)
{
    MyGetModel name = new MyGetModel();
    name.FullName = newName.FirstName + "" + newName.LastName; // Or validate and update the DB 
    return View("Create",name);
}
