ASP.NET MVC 3 RAZOR Modelsのデータ(配列とか)をViewsで使う

「/Views/Home/index.cshtml」「/Controllers/HomeController.cs」「/Models/IndexData.cs」の3ファイルが対象。
※ファイル名は適宜変更。

とりあえず「/Views/Home/index.cshtml」内で基本「@ViewBag.ReCatNap」ってな感じで使えるようにする

1. using System;
2. using System.Collections.Generic;
3. using System.Linq;
4. using System.Web;
5. using System.Web.Mvc;
6. using MvcApplication.Models;
7.  
8. namespace MvcApplication.Controllers
9. {
10.   public class HomeController : Controller
11.   {
12.     //
13.     // GET: /Home/
14.  
15.     public ActionResult Index()
16.     {
17.       ViewBag.ReCatNap = IndexData.GetReCatNapData();
18.  
19.       return View();
20.     }
21.   }
22. }

※「6行目：using MvcApplication.Models;」を記載することによって「17行目」の「IndexData.GetReCatNapData()」が利用可能になる。
※「6行目：using MvcApplication.Models;」を記載しない場合「17行目」の「IndexData.GetReCatNapData()」を「MvcApplication.Models.IndexData.GetReCatNapData()」とする。
