visual c++ fstream error

首先，我是一名硬件程序员（HDL，uC编程），几天前我的老板要求我创建一个可视化C++界面来控制uC。我以前从未使用过视觉C++，我的软件编程技能充其量是中级的。但是，我只需要到星期二才能使界面正常工作，因此由于我的时间框架，我不得不寻找示例并做同样的事情。因此，如果我问任何明显和愚蠢的问题，请原谅我。

在我的代码中，我必须将存储在数组中的值移动到 CSV 文件。所以我必须用逗号分隔我的值......但是，为了创建CSV文件，我必须使用fstream（据我目前所了解的内容）。每当我使用

#include <fstream>

我收到大量错误，例如：

1>c:program files (x86)microsoft visual studio 10.0vcincludecodeanalysissourceannotations.h(244): error C3083: 'vc_attributes': the symbol to the left of a '::' must be a type
1>c:program files (x86)microsoft visual studio 10.0vcincludecodeanalysissourceannotations.h(244): error C2039: 'YesNoMaybe' : is not a member of '`global namespace''

以下是我与 fstream 相关的其余代码：
