except sql query in code behind can we do it by sp

private void InsertRecords(StringCollection sc)
    {
        SqlConnection conn = new SqlConnection(GetConnectionString());
        StringBuilder sb = new StringBuilder(string.Empty);
        string[] splitItems = null;
        foreach (string item in sc)
        {

            const string sqlStatement = "INSERT INTO SampleTable (Column1,Column2,Column3) VALUES";
            if (item.Contains(","))
            {
                splitItems = item.Split(",".ToCharArray());
                sb.AppendFormat("{0}('{1}','{2}','{3}'); ", sqlStatement, splitItems[0], splitItems[1], splitItems[2]);
            }

        }

        try
        {
            conn.Open();
            SqlCommand cmd = new SqlCommand(sb.ToString(), conn);
            cmd.CommandType = CommandType.Text;
            cmd.ExecuteNonQuery();

            Page.ClientScript.RegisterClientScriptBlock(typeof(Page), "Script", "alert('Records Successfuly Saved!');", true);

        }
        catch (System.Data.SqlClient.SqlException ex)
        {
            string msg = "Insert Error:";
            msg += ex.Message;
            throw new Exception(msg);

        }
        finally
        {
            conn.Close();
        }
    }
