打造自己的 C# WinForm 应用程序的 SQL Server 连接配置界面
转载请注明出处：http://blog.csdn.net/CodingMouse/archive/2008/12/20/3565771.aspx
在C# WinForm 应用程序非常需要一个 SQL Server 连接配置界面，许多时候，因 SQL Server 服务器地址变更或 数据库登录账户 变更引起的连接失败等情况，客户就可能打电话“找麻烦”。既然这样，还不如提供一个可视化的配置界面，并在用户手册中说明使用方法，尽可能避免这种小问题带来的烦恼。为此，我将自己无聊时写的连接配置源码贴出来给初学者参考，以备不时之需！
想必大家都很熟悉VS服务器资源管理器中的【添加连接】对话框吧！下面是它的截图：
再看看我模仿这个对话框打造的WinForm程序SQL Server 连接配置界面：
呵呵！有几分相似吧！需要的朋友可以参考下面的源码。这份源码是完整的，粘贴到VS中即可使用。

在C# WinForm 应用程序非常需要一个 SQL Server 连接配置界面，许多时候，因 SQL Server 服务器地址变更或 数据库登录账户 变更引起的连接失败等情况，客户就可能打电话“找麻烦”。既然这样，还不如提供一个可视化的配置界面，并在用户手册中说明使用方法，尽可能避免这种小问题带来的烦恼。为此，我将自己无聊时写的连接配置源码贴出来给初学者参考，以备不时之需！
想必大家都很熟悉VS服务器资源管理器中的【添加连接】对话框吧！下面是它的截图：
再看看我模仿这个对话框打造的WinForm程序SQL Server 连接配置界面：
呵呵！有几分相似吧！需要的朋友可以参考下面的源码。这份源码是完整的，粘贴到VS中即可使用。
