Ado.net2.0中的事务处理

SqlConnection myConnection = new SqlConnection("Server=(local);Initial Catalog=Demo24;uid=sa;pwd=111;");
myConnection.Open();
// 启动一个事务
SqlTransaction myTrans = myConnection.BeginTransaction();

// 为事务创建一个命令
SqlCommand myCommand = new SqlCommand();
myCommand.Connection = myConnection;
myCommand.Transaction = myTrans;
try
{
myCommand.CommandText = "Insert into tbUserInfo (UserName, UserPass,Birthday,Score) VALUES ('成龙', '111','1966-1-1',540)";
myCommand.ExecuteNonQuery();
//myTrans.Commit();
myCommand.CommandText = "Insert into tbUserInfo (UserName, UserPass,Birthday,Score) VALUES ('王五', '222','198834',550)";
myCommand.ExecuteNonQuery();
myTrans.Commit();
MessageBox.Show("成功写入记录！");
}
catch
{
myTrans.Rollback();
MessageBox.Show("写入数据库失败！");
}
finally
{
myConnection.Close();
}
