با سلام
چگونه میشود از storeprocedure هایی که در اس کیو ال داریم در کلاس های زیر که dataaccess و BisnessLayer هستند استفاده کنم؟؟؟؟؟
کلاس dataaccesslayer
using System;using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Data;
using System.Data.SqlClient;
using DA;
namespace DA
{
public class DataAccessLayers
{
public static string p1;
public static string p2;
public static string p3;
public static bool p4;
SqlConnection con;
SqlDataAdapter da;
DataTable dt;
SqlCommand com;
public DataAccessLayers()
{
con = new SqlConnection();
da = new SqlDataAdapter();
com = new SqlCommand();
con.ConnectionString = @"Data Source='" + p1 + "';User Id ='" + p2 + "';Password='" + p3 + "';Database=SaveInfoStudent;Integrated Security=False";
}
public void connect()
{
con.Open();
}
public void disconnect()
{
con.Close();
}
public DataTable Select(string sql)
{
com.CommandText = sql;
DataTable dt = new DataTable();
da.Fill(dt);
return dt;
}
public void Docommand()
{
com.CommandType = CommandType.StoredProcedure;
com.ExecuteNonQuery();
}
}
}

و کلاس bisness :

//اینجا چطور عمل کنم؟؟؟؟؟؟؟؟
