/////ado.net1.0中使用Transacation（事务)string connectionString = "database=Northwind;pwd=admin;uid=sa;server=DATABASE-VPC\\SQL2005";using (SqlConnection conn = new SqlConnection(connectionString)){ conn.Open(); SqlTransaction transaction = conn.BeginTransaction(); try { using (SqlCommand cmd = new SqlCommand()) { cmd.Connection = conn; cmd.CommandType = CommandType.Text; cmd.CommandText = ""; cmd.Transaction = transaction; cmd.ExecuteNonQuery(); transaction.Commit();//提交事务 } } catch { transaction.Rollback();//事务回滚 }/////2.0中使用事务string connectionString = "database=Northwind;pwd=admin;uid=sa;server=DATABASE-VPC\\SQL2005";string connectionStringTwo = "database=Test;pwd=admin;uid=sa;server=DATABASE-VPC\\SQL2005";using (TransactionScope transaction = new TransactionScope())//使用事务{ try { using (SqlConnection conn = new SqlConnection(connectionString)) { using (SqlCommand cmd = new SqlCommand()) { cmd.CommandText = "insert into [member] (name) values ('test')"; cmd.CommandType = CommandType.Text; cmd.Connection = conn; conn.Open(); cmd.ExecuteNonQuery(); } } using (SqlConnection conn = new SqlConnection(connectionStringTwo)) { using (SqlCommand cmd = new SqlCommand()) { cmd.CommandText = "insert into [member] (name) values ('test')"; cmd.CommandType = CommandType.Text; cmd.Connection = conn; conn.Open(); cmd.ExecuteNonQuery(); } } transaction.Complete();//就这句就可以了。 } catch (Exception ex) { MessageBox.Show(ex.Message); }} |
ado.net1.0与ado.net2.0中对比
1.0中不能跨数据库，速度慢
2.0中可以跨数据库，2.0中不再使用com+，速度比1.0快50%（因为它不用把大量的时间消耗在查找在com+中)
2.0中的事务会自动判断使用何种事务（不用您考虑是简单事务还是分部式事务）。
2.0中的Transactions新添加了命名空间。没有com+注册和com+的开销。
希望本文所述对大家C#程序设计有所帮助。
