The only way to do it is to do a trial connection: set up a SqlConnection object, or a MySqlConnection (or whatever is appropriate) and Open it in a try...catch block. If it succeeds, the database is correct and reachable. If it doesn't, it isn't.

Any other way, such as checking to see if the server instance exists will not verify user login details.

Hi ,
You can use this

C#

SqlConnection con = new SqlConnection("your connection");
       if (con.State == System.Data.ConnectionState.Closed)
       {
           //con.open();
       }

Best Regards
