Question

我想在我的c ++代码中使用一些.Net命名空间。从here我发现，我怎么能这样做。在我的代码中，我有：

#include <iostream>
using namespace System;
using namespace System::Data;
using namespace System::Data::Sql;
using namespace Microsoft::Sqlserver::Server;
using namespace System::Data::SqlTypes;

using namespace std;

int main()
{


    cout << "Hello World!" << endl;
    return 0;
}

如果我运行它，我会收到这些错误：

0:08:06: Running steps for project Test...
10:08:06: Configuration unchanged, skipping qmake step.

我该怎么做才能解决这个问题？顺便说一句，我已经阅读了this和this帖子，但我无法理解，我的cpp代码中应该如何处理/ clr？

'System'不是名称空间名称
