C# MySQL Query error handler -

i'm new in visual studio world , need little help.

i'm writing program c# based , executes query when button pressed:

 private void button_login_click(object sender, eventargs e)     {         mysqldataadapter start_session;          start_session = new mysqldataadapter("here update query", connection);      } 

(the connection string on top of code).

is there way check if query returned errors or not ?

thank , sorry (i presume) trivial question.

the way check if error or not "exception". example (for sqlserver, mysql same) :

private void buttonloginclick(object sender, eventargs e) {     try     {         using (var sqliteconnection = new sqliteconnection(connstring))         {             sqliteconnection.open();             using (var sqlitecommand = new sqlitecommand(sql, sqliteconnection))             {                 sqlitecommand.executenonquery();             }         }         messagebox.show("success");     }     catch (exception ex)     {         messagebox.show("error : " + ex.message);     } }
