命名空間confilcts .NET C++

Question

我有一個項目，我一直在努力一段時間，並定期收到似乎來自Windows包含模糊符號錯誤。它們通常與.net命名空間相關。該項目包括託管和非託管C++代碼，我最近決定從使用文本文件登錄到通過ADO在非託管類中使用SQL服務器。在類的報頭我使用

#import <C:\\Program Files\\Common Files\\System\\ado\\msado15.dll> rename("EOF", "AdoNSEOF") 

由MS所建議 - http://msdn.microsoft.com/en-us/library/windows/desktop/ms675103(v=vs.85).aspx

在ADO帶來。這將編譯孤立罰款，但在管理部分包括，當我得到這樣的錯誤：

是否有某種方式來封裝衝突的命名空間，這樣它不會影響.NET？問題一直在出現，這裏似乎有些我不完全明白的地方。 非常感謝， 布魯斯。

Answer 1

您需要刪除一些使用的名稱空間聲明並使用那裏的全名來避免衝突。
