e将来我将使用“完整”SQL Server版本@Kaido，用户实例是我当时的想法。困扰我的是，我将如何编写从winforms应用程序到SQL Server的数据库附件。有什么建议吗？你能给我一个提示，如何从windows窗体（例如，使用ADO.NET）用C#代码实现这一点吗？谢谢。您必须执行存储过程来创建、附加和分离数据库。要在C#中执行此操作，您需要使用适当的连接字符串打开一个SqlConnection对象，创建一个SqlCommand对象，传递SqlConnection对象和附加或分离数据库的存储过程的名称，向SqlCommand对象添加一些参数对象，并使用ExecuteOnQuery（）执行SqlCommand。这里有一个完整的例子，大约在这一页的一半：谢谢你，罗伯特。你帮了我大忙。哇，这真让我高兴。其他人都在试图劝阻询问者不要尝试这个解决方案，而您只是随意地出现在一个简短、干净、简洁的代码列表中回答它。祝贺你，好先生，你赢得了我的选票。
