MVC之Model转Json

在开发中，有时我们需要在View层中拿到Model返回的数据并且是一个Json对象，那么我们就可以利用Newtonsoft.Json.JsonConvert.SerializeObject(Model)将Model层反序列化，由于js拿到反序列化的数据后一些特殊字符还需要处理，如：双引号"反序列化后会变成"，所以要将其替换成",str.replace(/"/g,"\"")，然后再用js函数JSON.parse将其转换，就得到一个Json对象

后台C#代码：

namespace MvcApplication1.Controllers

{

    public class HomeController : Controller

    {

        public ActionResult Index()

        {

            View_News View_News = new View_News();

            List<News> NewsList = new List<News>();

            NewsList.Add(new News() { Url = "www.baidu.com", Image = "/Resource/Skin02", Title = "Tom" });

            NewsList.Add(new News() { Url = "www.taobao.com", Image = "/Resource/Skin03", Title = "Jim" });

            NewsList.Add(new News() { Url = "www.jd.com", Image = "/Resource/Skin04", Title = "Jess" });

            View_News.NewsList = NewsList;

            return View(View_News);

        }

    }

    public class View_News

    {

        public List<News> NewsList { get; set; }

    }

    public class News

    {

        public string Url { get; set; }

        public string Image { get; set; }

        public string Title { get; set; }

    }

}

前台代码：

@model MvcApplication1.Controllers.View_News

@{

    Layout = null;

    string str = Newtonsoft.Json.JsonConvert.SerializeObject(Model.NewsList);

}

<!DOCTYPE html>

<html>

<head>

    <meta name="viewport" content="width=device-width" />

    <title>Index</title>

    <script src="~/Scripts/jquery-1.8.2.min.js"></script>

    <script type="text/javascript">

        var picData = {};

        var theString = '@(str)';

        theString = theString.replace(/&quot;/g,"\"");

        var temp = JSON.parse(theString);

        picData.news = temp;

        console.log(picData);

    </script>

</head>

输出结果：
