我可以使用“！do”来转储SqlConnection实例，但不知道如何找到它的ConnectionString：

0:018> !do 2fa7730

尝试使用Visual Studio 2008 debuger，调试使用SqlConnection的程序;

以您的首选方式查找SqlConnection实例（可能是本地var，实例字段或静态字段..）。

在Watch窗口中查看它。扩展它的每个可扩展子节点，直到你找到你想要的东西（因为我记得它分别存储服务器，数据库，用户ID，密码等部分）。

记录导航到这些字段的路径，然后使用windbg转到同一个字段。

如何使用windbg找出SqlConnection.ConnectionString？
