MVC的传递数据的方法

發(fā)布時間：2025/3/15 c/c++ 15 豆豆

生活随笔收集整理的這篇文章主要介紹了 MVC的传递数据的方法小編覺得挺不錯的,現(xiàn)在分享給大家,幫大家做個參考.

1、使用ViewBag

1 #region 0.2 Action方法 + ActionResult Index2() 2 /// <summary> 3 /// Action方法 4 /// </summary> 5 /// <returns></returns> 6 public ActionResult Index2() 7 { 8 System.Text.StringBuilder sbhtml = new System.Text.StringBuilder(); 9 List<Models.dog> list = InitData(); 10 list.ForEach(d => 11 { 12 sbhtml.AppendLine("<div>" + d.ToString() + "</div>"); 13 }); 14 15 ViewBag.HtmlStr = sbhtml.ToString(); 16 17 return View(); 18 } 19 #endregion View Code

Index2.cshtml

@{Layout = null; }<!DOCTYPE html><html> <head><meta name="viewport" content="width=device-width" /><title>Index</title> </head> <body>@Html.Raw(ViewBag.HtmlStr)</body> </html> View Code

2、使用ViewData

1 #region 0.3 查詢文章列表 + ActionResult Index3() 2 /// <summary> 3 /// 查詢文章列表 4 /// </summary> 5 /// <returns></returns> 6 OumindBlogEntities db = new OumindBlogEntities(); 7 8 public ActionResult Index3() 9 { 10 List<Models.BlogArticle> list = (from d in db.BlogArticles where d.AIsDel == false select d).ToList(); 11 12 ViewData["DataList"] = list; 13 return View(); 14 } 15 #endregion View Code

Index3.cshtml

@using MvcLewisTest.Models; @{Layout = null; }<!DOCTYPE html><html> <head><meta name="viewport" content="width=device-width" /><title>Index</title><style type="text/css">#tbList{border:1px solid #0094ff;border-collapse:collapse;margin:10px auto;width:800px;}#tbList th,td{border:1px solid #0094ff;padding:10px;}</style><script type="text/javascript">function del(Aid) {if (confirm("確定要刪除嗎？"))window.location = "/Home/Del/" + Aid; }</script> </head> <body><table id="tbList"><tr> <th>id</th><th>標(biāo)題</th><th>分類</th><th>狀態(tài)</th><th>時間</th><th>操作</th></tr>@foreach (BlogArticle a in ViewData["DataList"] as List<BlogArticle>) {<tr> <td>@a.AId</td><td>@a.ATitle</td><td>@a.BlogArticleCate.Name</td><td>@a.Enumeration.e_cname</td><td>@a.AAddtime</td><td><a href="javascript:del(@a.AId)">刪</a><a href="/Home/Modify/@a.AId">改</a></td></tr>}</table> </body> </html> View Code

3、使用Control器的 return?View()

1 #region 0.5 顯示要修改數(shù)據(jù)（根據(jù)Id) + ActionResult Modify(int id) 2 [HttpGet] 3 /// <summary> 4 /// 顯示要修改的數(shù)據(jù) 5 /// </summary> 6 /// <param name="id"></param> 7 /// <returns></returns> 8 public ActionResult Modify(int id) 9 { 10 //1.根據(jù)id查詢出要修改的對象 11 BlogArticle art = (from a in db.BlogArticles where a.AId == id select a).FirstOrDefault(); 12 //2.生產(chǎn)文章分類下來框 13 IEnumerable<SelectListItem> listItem = (from c in db.BlogArticleCates 14 where c.IsDel == false select c).ToList() 15 .Select(c => new SelectListItem { Value = c.Id.ToString(), Text = c.Name }); 16 //3.將生成的文章分類下拉框集合設(shè)置給ViewBag 17 ViewBag.CateList = listItem; 18 //4.加載視圖，使用View構(gòu)造函數(shù)，將數(shù)據(jù)傳給視圖上Model屬性 19 return View(art); 20 } 21 #endregion View Code
