how to check if database exists in MySQL server?

Question

Hello everyone,

 

 I am using WPF apps with MySQL database. I did create backup.sql file. Then, after create .exe file, how can I check if db exist then skip below code?

private void Application_Startup(object sender, StartupEventArgs e)
        {
            RestoreBehavior();
        }

 

private void RestoreBehavior()
        {
            string constring = "server=localhost;user=root;pwd=123456;";
            string file = @"C:\Program Files (x86)\xxxx\xxxx\backup.sql";
            using (MySqlConnection conn = new MySqlConnection(constring))
            {
                using (MySqlCommand cmd = new MySqlCommand())
                {
                    using (MySqlBackup mb = new MySqlBackup(cmd))
                    {
                        cmd.Connection = conn;
                        conn.Open();
                        mb.ImportInfo.TargetDatabase = "mydb";/*Here,How can I check here if mydb exist then skip the code?*/
                        mb.ImportInfo.DatabaseDefaultCharSet = "utf8";
                        mb.ImportFromFile(file);
                    }
                }
            }
        }
