我想实现一个“smartODBCLogin”。我知道如何从注册表中获取来自所有ODBC数据源的所有EngineName和驱动程序的列表

现在我想知道，这些资源中哪些是可用的（活动的）。（打开新的ODBC连接不起作用，需要花费很多时间。）

有人知道如何在c#中实现这一点吗？

没有.NET API（我知道），但有一个本机ODBC API。还有一个列出用户和系统DSN的nice。CodeProject中还有一个代码示例

如果您赶时间，以下是第一篇文章示例（用于获取用户和系统DSN），展示了他们剽窃的荣耀：

没有用于此的.NET API（据我所知），但有用于此的本机ODBC API。还有一个列出用户和系统DSN的nice。CodeProject中还有一个代码示例
如果您赶时间，以下是第一篇文章示例（用于获取用户和系统DSN），展示了他们剽窃的荣耀：
