C#实现数据库事务处理的简单示例代码

    　　最近做了个小项目，其中要对两个表同时进行插入insert操作处理，而且对它们的插入操作要么全部成功，要么都插入失败，否则只插入一个表成功会引起数据库的不一致。很显然，这是一个事务处理(transcation)，要么commit成功，要么则rollback。在代码中，我利用的是C#中提供的Transcation类来实现，代码如下：

        private void btn_submit_Click(object sender, System.EventArgs e)        {            string strconn = ConfigurationSettings.AppSettings["dsn"];            SqlConnection cnn = new SqlConnection(strconn);            SqlCommand cmd = new SqlCommand();            SqlTransaction transaction = null;            try            {                cnn.Open();

                // 先插入分店shop表，再插入经理Manager表，并将其作为一个事务进行处理                transaction = cnn.BeginTransaction();                cmd.Transaction = transaction;                cmd.Connection = cnn;

                // 插入分店shop表                string shopstr = "insert into shop values('" + tbx_shopid.Text + "','" + tbx_shopname.Text + "','" + tbx_shopaddress.Text + "','" + tbx_shopphone.Text + "')";                cmd.CommandType = CommandType.Text;                cmd.CommandText = shopstr;                cmd.ExecuteNonQuery();                // 插入经理Manager表                string managerstr = "insert into manager values('" + tbx_managerid.Text + "','" + tbx_managerpassword.Text + "','" + tbx_managername.Text + "','" + tbx_shopid.Text + "')";                cmd.CommandType = CommandType.Text;                cmd.CommandText = managerstr;                cmd.ExecuteNonQuery();                // 提交事务                transaction.Commit();                lbl_msg.Text = "添加分店操作成功";            }            catch(Exception ex)            {                lbl_msg.Text = "添加分店操作失败";                transaction.Rollback();            }            finally            {                cnn.Close();            }        }
