System.Transactions事务详解[上篇]分析.docVIP

System.Transactions事务详解[上篇] 在.NET 1.x中，我们基本是通过ADO.NET实现对不同数据库访问的事务。.NET 2.0为了带来了全新的事务编程模式，由于所有事务组件或者类型均定义在System.Transactions程序集中的System.Transactions命名空间下，我们直接称基于此的事务为System.Transactions事务。System.Transactions事务编程模型使我们可以显式（通过System.Transactions.Transaction）或者隐式（基于System.Transactions.TransactionScope）的方式进行事务编程。我们先来看看，这种全新的事务如何表示。 一、System.Transactions.Transaction 在System.Transactions事务体系下，事务本身通过类型System.Transactions.Transaction类型表示，下面是Transaction的定义： 1: [Serializable] 2: public class Transaction : IDisposable, ISerializable 3: { 4: public event TransactionCompletedEventHandler TransactionCompleted; 5: 6: public Transaction Clone(); 7: public DependentTransaction DependentClone(DependentCloneOption cloneOption); 8: 9: public Enlistment EnlistDurable(Guid resourceManagerIdentifier, IEnlistmentNotification enlistmentNotification, EnlistmentOptions enlistmentOptions); 10: public Enlistment EnlistDurable(Guid resourceManagerIdentifier, ISinglePhaseNotification singlePhaseNotification, EnlistmentOptions enlistmentOptions); 11: public bool EnlistPromotableSinglePhase(IPromotableSinglePhaseNotification promotableSinglePhaseNotification); 12: public Enlistment EnlistVolatile(IEnlistmentNotification enlistmentNotification, EnlistmentOptions enlistmentOptions); 13: public Enlistment EnlistVolatile(ISinglePhaseNotification singlePhaseNotification, EnlistmentOptions enlistmentOptions); 14: 15: public void Rollback(); 16: public void Rollback(Exception e); 17: 18: void ISerializable.GetObjectData(SerializationInfo serializationInfo, StreamingContext context); 19: 20: public static Transaction Current { get; set; } 21: 22: public IsolationLevel IsolationLevel { get; } 23: public TransactionInformation TransactionInformation { get; } 24: } 1、Transaction是可序列化的 从上面的定义我们可以看到，Transaction类型（在没有特殊说明的情况下，以下的Transaction类型指的就是System.Transactions.Transa
