如何使用 ASP.NET MVC 在视图页面中显示自定义对象属性？

发布于 2024-09-04 05:06:25 字数 762 浏览 4 评论 0原文

我正在尝试将 ASP.NET MVC 功能（尤其是路由）添加到我现有的 ASP.NET Web 应用程序中。我添加了一个控制器和视图（一个 asp.net 页面）。

现在我想知道如何在视图中显示自定义类（例如用户）的对象的详细信息？我可以分配 ViewData 集合中的对象并将其呈现在视图中吗？我已经有一个为当前 ASP.NET Web 应用程序运行的 Datalayer（在 ADO.NET 中），所以我想使用它。

我在我的控制器中尝试了这个

public ActionResult Index()
    {
        BusinessObject.User objUser = new BusinessObject.User();
        objUser.EmailId = "[email protected]";
        objUser.ProfileTitle = "Web developer with 6 yrs expereince";

        ViewData["objUser"] = objUser;
        ViewData["Message"] = "This is ASP.NET MVC!";

        return View();
    }

如何在视图页面中使用它来显示用户详细信息？

原文

I am trying to add ASP.NET MVC features (especially routing) to my already existing ASP.NET web application. I added a Controller and View (an asp.net page).

Now I want to know how can I display the details of object of my custom class (for example, User) in the view? Can I assign the object in ViewData collection and render it in the view? I already have a Datalayer (in ADO.NET) which is running for the the current ASP.NET web app, so I want to use that.

I tried this in my controller

public ActionResult Index()
    {
        BusinessObject.User objUser = new BusinessObject.User();
        objUser.EmailId = "[email protected]";
        objUser.ProfileTitle = "Web developer with 6 yrs expereince";

        ViewData["objUser"] = objUser;
        ViewData["Message"] = "This is ASP.NET MVC!";

        return View();
    }

How can I use this in the view page to display the user details ?

您应该将对象作为视图模型（或视图模型的一部分，以及您的消息）传递给强类型视图。然后您可以简单地在视图中引用模型属性。

public class IndexViewModel
{
    public BusinessObject.User User { get; set; }
    public string Message { get; set; }
}

（或者，更好的是，只是您真正需要的用户对象的属性）

控制器

public ActionResult Index()
{
    BusinessObject.User objUser = new BusinessObject.User();
    objUser.EmailId = "[email protected]";
    objUser.ProfileTitle = "Web developer with 6 yrs expereince";

    return View( new IndexViewModel {
         User = objUser,
         Message = "This is ASP.NET MVC!";
    });
}

视图

<%@ Page Title="" Language="C#"
    MasterPageFile="~/Views/Shared/Site.Master"
    Inherits="System.Web.MVC.ViewPage<MyWebSite.Models.IndexViewModel>" %>

<%= Html.Encode( Model.User.EmailId ) %>

You should pass your object as a view model (or part of a view model, along with your message) to a strongly-typed view. Then you can simply reference the model properties in your view.

public class IndexViewModel
{
    public BusinessObject.User User { get; set; }
    public string Message { get; set; }
}

(or, better yet, just the properties from the user object that you really need)

Controller

public ActionResult Index()
{
    BusinessObject.User objUser = new BusinessObject.User();
    objUser.EmailId = "[email protected]";
    objUser.ProfileTitle = "Web developer with 6 yrs expereince";

    return View( new IndexViewModel {
         User = objUser,
         Message = "This is ASP.NET MVC!";
    });
}

View

<%@ Page Title="" Language="C#"
    MasterPageFile="~/Views/Shared/Site.Master"
    Inherits="System.Web.MVC.ViewPage<MyWebSite.Models.IndexViewModel>" %>

<%= Html.Encode( Model.User.EmailId ) %>
