推荐答案

没有工具可以自动执行此操作.您可以通过编程方式在Web.Config中修改ConnectionString.

There is no tool to automate this. You can modify the ConnectionString in Web.Config programmatically.

通常，如果发生故障转移等情况，您将使用名称而不是IP地址作为连接字符串.最好创建一个DNS别名并将其更改为备份服务器.

这样，您的服务器名称始终是相同的.

Usually you would use a name instead of IP addresses for your connection string, in the event of failovers etc. it is best to create a DNS alias and change that to a backup server.

This way your server name is always the same.

您的应用程序如何直接知道服务器名称已更改?

这是定制的活动.您需要编写一个代码/EXE，服务器名称更改后应由用户触发.

How your application knows directly, that Server name has changed ?

This is customized activity. you need to write a code/EXE which should triggered by user after server name has change.
