How i can Build Connection String with Data Source (Oracle, SqlClient, Mysql) Rather then Data Link Properties

Hello Dear

i am using data link properties component in our previous development for oledb connection with this code.

 MSDASC.DataLinks MyDlg = new MSDASC.DataLinks();

          ADODB._Connection ADODBCon;
           ADODBCon = (ADODB._Connection)MyDlg.PromptNew();

        MessageBox.Show(ADODBCon.ConnectionString);

             

But now i am trying to find connection string with .Net Framework Data Provider for Specialize DBMS like Oracle, SqlClient. Please guide me how i can get such type of this Source Control for connection builder.
