do you mean : you have 1 class , in this class you open the connection to database , create sqlcommand and execute it , get parameters is the sql query from outside?
then in the form you want, you call back the before class ?

first, you create new class vd ketnoi.cson the class ketnoi

in the using library, you use System.Data.SqlClient;

you create 1 method taoKetNoipublic void KetNoi()
{

SqlConnection KetNoiMoi=new SqlConnection();

KetNoiMoi.ConnectionString=@"DataSource=./sqlexpress;initial catalog=YourDataBaseName(not include the extension of file);persist security=true;pooling=false";

KetNoiMoi.Open();}
//i don't have enough time, the next time ok
