最后，我找到了解决办法。错误是：当您恢复* .bak文件时，* .mdf和* .ldf文件被复制到一个特殊的目录。例如：当我在“C：\ Program Files \ Microsoft SQL Server \ MSSQL10_50.SQL2008RR2 \ MSSQL \ DATA \”下复制* .bak文件时，我的* .mdf和* .ldf文件被复制。所以：如果* .mdf或* .ldf文件的名称相同，则可以像我那样获得异常。我用更改* .mdf和* .ldf文件路径解决它。我写了belov代码，它正在工作。

什么是完整的错误信息？ – ChrisBint 2013-02-11 14:00:27
我编辑了这个问题。谢谢你的时间，克里斯宾特。 – 2013-02-11 14:04:45
什么是内部异常？由SQL Server生成的那个？ – gbn 2013-02-11 14:16:32
