当我尝试查看在 WebGrid 中显示产品数据的网页时，我收到“无效列”错误。

我目前正在运行完全相同的代码的实时版本，它可以工作。但是，此本地版本不适用于此 1 个特定页面。

在此处输入图像描述

如您所见，下图中引用的代码与错误消息下方描述的列名称完全匹配。

我完全被难住了。我不知道现在该做什么。它告诉我“无效列”，但事实并非如此。它就在那里，我三重检查了我的代码中的任何拼写错误（如下所示），一切都很好！

是什么赋予了？

<div id="grid">
  @grid.GetHtml(
    headerStyle : "HeaderStyle",
    columns: grid.Columns(
      grid.Column(
        columnName : "PartNumber",
        header : "Part Number",
        style : "PartNumberStyle"
      ),
      grid.Column(
        columnName : "Product",
        header : "Description"
      ),
      grid.Column(
        columnName : "Quantity",
        header : "Quantity"
      ),
      grid.Column(
        columnName : "ZincPlatedCL2UnitPrice",
        header : "Zinc Plated CL2 Unit Price",
        format: @<a href="?Action=Add&PartNumber=@item["PartNumber"]&Product=@item["Product"]&Type=Zinc Plated CL2 Unit Price&Units=1&UnitPrice=@item["ZincPlatedCL2UnitPrice"]&IsBoxed=0">@item["ZincPlatedCL2UnitPrice"]</a>
      ),
      grid.Column(
        columnName : "ZincPlatedCL2BoxPrice",
        header : "Zinc Plated CL2 Box Price",
        format: @<a href="?Action=Add&PartNumber=@item["PartNumber"]&Product=@item["Product"]&Type=Zinc Plated CL2 Box Price&Units=1&BoxPrice=@item["ZincPlatedCL2BoxPrice"]&IsBoxed=1">@item["ZincPlatedCL2BoxPrice"]</a>
      )
    )
  )
</div>

调试时，异常指向这行代码：

format: @<a href="?Action=Add&PartNumber=@item["PartNumber"]&Product=@item["Product"]&Type=Zinc Plated CL2 Unit Price&Units=1&UnitPrice=@item["ZincPlatedCL2UnitPrice"]&IsBoxed=0">@item["ZincPlatedCL2UnitPrice"]</a>

您是否确实检查了本地数据库以确保该列在架构中？与您的实体框架架构相比，您的本地数据库可能是“旧的”。
