Visual Studio C# 不识别右大括号

Question

我正在使用 Visual Studio，制作一个 .CSHTML 网页。 该代码是工作代码。 通过一些未知的编辑？ 或错误？（不太可能）Visual Studio 将无法识别最后一组 {}。 以@{ 开头的 C# 代码在这里

}

编译器错误：“解析器错误消息：代码块缺少结束的“}”字符。确保此块中的所有“{”字符都具有匹配的“}”字符，并且没有“}”字符被解释为标记。

源错误：

第 2 行：
第 3 行：
第 4 行：@{ 第 5 行：var db = Database.Open("DevDbCS"); 第 6 行：
”

我已将我的代码复制并粘贴到记事本++，如果我选择一个，它会突出显示相应的括号。 我已确认所有制动器都正确打开和关闭。 我什至把它放到了 Processing 中，（不会编译）但它也说一切都很好。

当它到达我的 !DOCTYPE html 时，它告诉我“找不到类型或命名空间名称 'DOCTYPE'....）可能是因为它无法弄清楚右括号在哪里。

我哪里错了？ 非常令人沮丧的是，编译器消息没有帮助，因为所有大括号都是正确的！

Answer 1

尝试删除此行中等号和 db 变量之间的左括号：

var RecordCount2 = (db.Query ....

这没有匹配的右括号。 因此，编译器无法将后面的大括号与开头的大括号匹配，并显示误导性错误
