C# MVC后台传值到前端并显示

一、通过ViewBag传值：传值可以是字段和list等其他类型

后台代码

ViewBag.Message = "Your application description page.";
ViewBag.Message2 = "Your application description page2.";

ViewBag.Message3 = "Your application description page3.";

html页面获取代码：

    <h2>ViewBag</h2>
    <h3>@ViewBag.Title.</h3>
      <h3>@ViewBag.Message</h3>
    <h3>@ViewBag.Message2</h3>

<h3>@ViewBag.Message3</h3>

二、通过ViewData：传值可以是字段和list等其他类型

后台代码：

ViewData["mess1"] = "测试1";

ViewData["mess2"] = "测试2";

List<ZSKObj> zsk = new List<ZSKObj>();

zsk.Add(new ZSKObj {ZSKDM=1, FLMC="分类1", LXMC="整改措施", MEMO="整改测试1" });
zsk.Add(new ZSKObj { ZSKDM = 2, FLMC = "分类2", LXMC = "原因分析", MEMO = "原因分析测试1" });
zsk.Add(new ZSKObj { ZSKDM = 3, FLMC = "分类1", LXMC = "整改措施", MEMO = "整改测试2" });

ViewData["list"] = zsk;

HTML页面获取代码：

<h2>ViewData</h2>
<h3>@ViewData["mess1"]</h3>

<h3>@ViewData["mess2"]</h3>

<table class="table table-striped table-bordered">
<thead>
<tr>
<th>类型</th>
<th>分类</th>
<th>明细</th>
<th>操作</th>
</tr>
</thead>
<tbody>
@foreach (var item in ViewData["list"] as List<Winning.NQCS.DAL.DataObject.Settings.ZSKObj>)
{
<tr>
<td>@Html.DisplayFor(p => item.FLMC)</td>
<td>@Html.DisplayFor(p => item.LXMC)</td>
<td>@Html.DisplayFor(p => item.MEMO)</td>
<td>@Html.ActionLink("编辑", "UpdateZSK", "ZSK", new { zskdm = item.ZSKDM.ToString() }, null) </td>
</tr>
}
</tbody>

</table>

三、通过TempData：传值可以是字段和list等其他类型，用法通ViewData

后台代码：

TempData["Tmptest1"] = "Tmptest1";

TempData["Tmptest2"] = "Tmptest2";

HTML页面获取代码：

<h3>@TempData["Tmptest1"]</h3>

<h3>@TempData["Tmptest2"]</h3>

四、直接在View中进行返回

后台代码：

List<ZSKObj> zsk = new List<ZSKObj>();
zsk.Add(new ZSKObj {ZSKDM=1, FLMC="分类1", LXMC="整改措施", MEMO="整改测试1" });
zsk.Add(new ZSKObj { ZSKDM = 2, FLMC = "分类2", LXMC = "原因分析", MEMO = "原因分析测试1" });
zsk.Add(new ZSKObj { ZSKDM = 3, FLMC = "分类1", LXMC = "整改措施", MEMO = "整改测试2" });
ViewData["list"] = zsk;

return View(zsk);

HTML页面获取代码：

ViewBag.Title = "About";
}
@model IEnumerable<Winning.NQCS.DAL.DataObject.Settings.ZSKObj>

传递单个对象：

public ActionResult Edit(string id)
{
List<UserInfoViewModel> dataList = HttpContext.Session["TestData"] as List<UserInfoViewModel>;
UserInfoViewModel item = dataList.Find(p => p.UserID.ToString() == id);
return View("Detail", item);

}

html代码：

@model MVC5Demo1.Models.UserInfoViewModel

@Html.HiddenFor(p => p.UserID)
<div class="form-group">
<label for="txtUserName" class="col-sm-2 control-label">姓名</label>
<div class="col-sm-10">
@Html.TextBoxFor(p => p.UserName, new { @class="form-control", placeholder = "姓名" })
</div>

</div>
