Looks like your MySQL credentials (username and password) might be wrong, and the error is occuring when it tries to retrieve the message for the error:
... /home/l/桌面/mono_src/mcs/class/corlib/System.Resources/ResourceManager.cs:252 at MySql.Data.MySqlClient.Properties.Resources.get_*AuthenticationFailed*() [0x00000] in <filename unknown>:0 at MySql.Data.MySqlClient.Authentication.MySqlAuthenticationPlugin.* AuthenticationFailed* (System.Exception ex) [0x00000] in <filename unknown>:0 ... Try checking that the username and password are valid.
