推荐答案

否当驱动程序未加载或连接字符串错误时，会显示合适的驱动程序错误。可能是后者，但肯定也可能是前者，因为你在加载驱动程序时正在吃异常。

The "no suitable driver" error shows up when either the driver isn''t loaded or the connection string is wrong. Could be the latter, but certainly could be the former as well because you are eating the exception when it loads the driver.
