我有一个项目，我一直在努力一段时间，并定期收到似乎来自Windows包含模糊符号错误。它们通常与.net命名空间相关。该项目包括托管和非托管C++代码，我最近决定从使用文本文件登录到通过ADO在非托管类中使用SQL服务器。在类的报头我使用命名空间confilcts .NET C++
#import <C:\\Program Files\\Common Files\\System\\ado\\msado15.dll> rename("EOF", "AdoNSEOF")
由MS所建议 - http://msdn.microsoft.com/en-us/library/windows/desktop/ms675103(v=vs.85).aspx
在ADO带来。这将编译孤立罚款，但在管理部分包括，当我得到这样的错误：

是否有某种方式来封装冲突的命名空间，这样它不会影响.NET？问题一直在出现，这里似乎有些我不完全明白的地方。 非常感谢， 布鲁斯。
