ado.net2.0的SqlTransaction使用方法/////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。*/ |
