ASP.NET MVC3 中的编译错误 CS0103

Question

我正在使用 ASP.NET 和 SQL Server 2012 开发一个项目，当我尝试加载该项目时，它显示：

Compilation Error CS0103: The name 'model' does not exist in the current context

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

你的问题出在这里：

@foreach (var item in model) {

改为：

@foreach (var item in Model) {

小写模型不是什么，大写是ViewPage的成员class。

附带说明一下，如果您没有几乎在所有地方都使用 "model" 这个词，那么找到它会更容易......当您遇到这些问题时，请尽可能地开始重命名。这可以帮助缩小范围。

我在手动创建 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。请看下面。

<?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">

  <system.web>

    </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.
