Hello everybody i have a MySQL connection problem in C#. This is my problem in the picture. thanks for help me. Picture


What a hideous sidebar, hahaha, I'm sorry.

The problem is that the MySQL client in your C# program cannot connect to the MySQL server. Are you able to log into the MySQL server yourself? You may be connecting from another machine with a user that is only locally available.

Please check the permissions/credentials of the user you're trying to log in to your server as.

Also check that the server is online, and on what ip/host/domain/port it is running.

This is a typical connection problem. There is nothing wrong with MonoDevelop, or the libraries it uses. It is your configuration, code and/or system that produces this error, so without more information on the set-up there is nothing more I/we can help with right now.

Good luck.


Additionally, did you install the MySQL connector/NET?

Good luck!
