How to solve the problem of attaching a database to SQL, and attaching a database to SQL

The database was used for laziness, but an error occurred while attaching the database.
The error is as follows:

At first, I thought there was a problem with the database location, so I placed a new location, which is still invalid. Finally, find a solution on the Internet. Fortunately, some people have encountered such problems and there are several solutions. I used two methods to share them:
