如何使用windbg查找SqlConnection.ConnectionString？

Question

我可以用“做！”转储SqlConnection的实例，但不知道如何找出它的ConnectionString：

Answer 1

尝试Visual Studio 2008中debuger，调试它使用的SqlConnection程序;

找到SqlConnection实例的方式（它可能是本地变量，实例字段或静态字段..）。

在观察窗口中查看它。展开它的每个可展开的子节点，直到找到你想要的东西（因为我可以记住它单独存储诸如服务器，数据库，用户ID，密码等部分）。

记录如何导航到这些字段的路径，然后使用windbg转到相同的字段。
