临时构建文件中的语法错误

Question

我正在为内部网站构建一个相当标准的 razor/c# 页面。它基本上是一个为 db 查询提供有效参数的查询的包装器。

页面在构建时在 Asp_Web_?????.cshtml 中生成错误。对于我的一生，我找不到错误。以下是页面的来源

    Layout = "~/_SiteLayout.cshtml";
    Page.Title = "ABC Floor Limits";
}

错误详情如下：

错误编号： 1

临时文件中的错误是EndContext引用：

BeginContext("~/VeoliaFloor.cshtml", 5970, 36, true);
WriteLiteral(" />\r\n        </form>\r\n    </div>\r\n\r\n");
EndContext("~/VeoliaFloor.cshtml", 5970, 36, true);

我已安装颜色匹配 {} 工具来提供帮助。页面似乎没有问题，只有编译到临时文件时。这让我发疯了。

Answer 1

这是因为您在声明方法的部分中缺少 @functions 关键字。
