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用 Visual C++ 创建一个接口来控制 uC。我以前从未使用过 Visual C++，我的软件编程技能充其量只是中等水平。但是，我只有到周二才能让界面工作，因此由于我有时间框架，我不得不寻找示例并做同样的事情。所以，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 文件中。所以我必须使用逗号分隔我的值......但是，为了创建一个 CSV 文件，我必须使用 fstream （据我到目前为止所读的内容）。每当我使用
#include <fstream>
我收到大量错误，例如：
1>c:\program files (x86)\microsoft visual studio 10.0\vc\include\codeanalysis\sourceannotations.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 10.0\vc\include\codeanalysis\sourceannotations.h(244): error C2039: 'YesNoMaybe' : is not a member of '`global namespace''
这是我与 fstream 相关的其余代码：

我希望在这里得到一些帮助或至少任何有用的信息。
