Question

我正在开发一个使用ASP.NET和SQL Server 2012的项目，当我尝试加载项目时，它说：

编译错误CS0103：名称'model'不存在于当前背景

这是我的代码：

@model IEnumerable<SegundoParcialP3.Models.Productos>

@{
    ViewBag.Title = "Index";
}

<h2>Index</h2>

<p>
    @Html.ActionLink("Create New", "Create")
</p>
@using(Html.BeginForm())
{}
<table>
    <tr>
        <th>
            @Html.DisplayNameFor(model => model.Nombre)
        </th>
        <th>
            @Html.DisplayNameFor(model => model.Id)
        </th>
        <th>
            @Html.DisplayNameFor(model => model.Precio)
        </th>
        <th></th>
    </tr>

@foreach (var item in model) {
    <tr> 
        <td>
            @Html.DisplayFor(modelItem => item.Nombre)
        </td>
        <td>
            @Html.DisplayFor(modelItem => item.Id)
        </td>
        <td>
            @Html.DisplayFor(modelItem => item.Precio)
        </td>
    </tr>
}
    <tr> 
        <td>
            @Html.ActionLink("Edit", "Edit") |@*, new { id=item.Id }*@
            @Html.ActionLink("Details", "Details") |@*, new { id=item.Id }*@
            @Html.ActionLink("Delete", "Delete") | @*, new { id=item.Id }*@
        </td>
    </tr>


</table>

Answer 1

你的问题在于：

@foreach (var item in model) {

将其更改为：

@foreach (var item in Model) {

小写模型不是任何东西，大写是ViewPage类的成员。

作为旁注，如果您没有使用“＃34; model＆＃34;”这个词，那么就更容易找到它。几乎无处不在...当您遇到这些问题时，请尽可能重新命名。这可以帮助缩小范围。

我手动创建Views文件夹时遇到了同样的问题。修复：我在Views文件夹下创建了一个Web.config文件，并添加了配置详细信息。请参阅下文。

<?xml version="1.0"?>
<configuration>
  <configSections>
    <sectionGroup name="system.web.webPages.razor" type="System.Web.WebPages.Razor.Configuration.RazorWebSectionGroup, System.Web.WebPages.Razor, Version=2.0.0.0, Culture=neutral, PublicKeyToken=31BF3856AD364E35">

      <section name="pages" type="System.Web.WebPages.Razor.Configuration.RazorPagesSection, System.Web.WebPages.Razor, Version=3.0.0.0, Culture=neutral, PublicKeyToken=31BF3856AD364E35" requirePermission="false" />
    </sectionGroup>
  </configSections>

        <add namespace="System.Web.Mvc.Html" />
        <add namespace="System.Web.Optimization"/>
        <add namespace="System.Web.Routing" />
      </namespaces>
    </pages>
  </system.web.webPages.razor>

  <appSettings>
    <add key="webpages:Enabled" value="false" />
  </appSettings>

  <system.web>
    <httpHandlers>
      <add path="*" verb="*" type="System.Web.HttpNotFoundHandler"/>
    </httpHandlers>

    <!--
        Enabling request validation in view pages would cause validation to occur
        after the input has already been processed by the controller. By default
        MVC performs request validation before a controller processes the input.
        To change this behavior apply the ValidateInputAttribute to a
        controller or action.
