C# SqlTransaction的使用

Sqltransaction 是用在多sql任务写数据库时的

 

using (SqlConnection conn = new SqlConnection(SqlHelper.ConnectionString))
            {
               
                conn.Open();
                SqlTransaction trans = conn.BeginTransaction();
                
                try
                {
                    foreach (DataRow row in dt.Rows)
                    //DataRow row = dt.Rows[0];
                    {
                        //PriceProvider.ModifySupplier(null, txtCustomerID.Text, row["productVariantID"].ToString(), ddlSupp.SelectedValue);
                        PriceProvider.ModifySalesPricePerProduct(trans, txtCustomerID.Text, row["ProductVariantID"].ToString(),
                                 ddlBaseonPriceLevel1.SelectedItem.Text, txtCustomerID.Text, txtFormula1.Text, ddlCurrency1.SelectedItem.Text,
                                 Convert.ToDateTime(TxtValidateEndDate1.Text), txtRemarks.Text);

                        //lblmsgSupp.Text =lblmsgSupp.Text+ row["productVariantID"].ToString();
                    }
                    trans.Commit();
                    trans.Dispose();
                    trans = null;

                    lblmsgSupp.Text = "succeed";
                    initDataTable();
                }
                catch
                {
                   // trans1.Rollback();
                    trans.Rollback();
                    //lblmsgSupp.Text = conn.ConnectionTimeout.ToString();
                    throw;
                }
