通过ADO.NET实现事务处理

   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);
    }
    }
