ASP.NET MVC3中的編譯錯誤CS0103

Question

我正在使用ASP.NET和SQL Server 2012開發一個項目，當我嘗試加載該項目時，它說：

編譯錯誤CS0103：名稱“模型”在當前上下文中不存在

這是我的代碼：

@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

您的問題出在這里：

@foreach (var item in model) {

更改為：

@foreach (var item in Model) {

小寫模型不是什么，大寫是ViewPage類的成員。

附帶說明一下，如果您幾乎沒有在所有地方都使用“模型”一詞，則查找起來會更容易...當遇到這些問題時，請盡可能重命名。 這可以幫助縮小范圍。

手動創建Views文件夾時遇到相同的問題。 修復：我在“視圖”文件夾下創建了一個Web.config文件，並添加了配置詳細信息。 請看下面。

        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.
