在数据库连接上创建事务处理对象,然后调用事务处理对象来提交事务或回滚事务。简单的代码:
PRivate void button1_Click(object sender, System.EventArgs e)
  {
  SqlConnection conn = new SqlConnection("Data Source=192.168.2.200;uid=sa; passWord=;database = HaierHR");
  conn.Open();
  //启用事务
  SqlTransaction tran = conn.BeginTransaction();
  SqlCommand cmd = new SqlCommand();
  cmd.Connection = conn;
  cmd.Transaction = tran;
  try
  {
   cmd.CommandText = "UPDATE HRRollMain Set TotalMember=TotalMember-100 WHERE RollID = '2005070101'";
   cmd.ExecuteNonQuery();
   cmd.CommandText = "UPDATE HRRollSum Set TotalSumMember=TotalSumMember+100 WHERE RollSumID = '20050701'";
   cmd.ExecuteNonQuery();
   tran.Commit();
   MessageBox.Show("事务提交成功!");
  }
  catch(Exception ex)
  {
   tran.Rollback();
   MessageBox.Show("Error!"+ex.Message);
  }  
  }
