关于业务有涉及到事务的，例子简单使用，就基本知识而已。只是EF的版本不同，写法不同罢了。 1using (var trans = _db.Database.BeginTransaction()) //EF 6.0版本；EF 4.0版本是：_db.Database.Connection.BeginTransaction() 2{3 4//业务逻辑代码 5 6 _db.Entry<Model>(model).State = System.Data.Entity.EntityState.Add;7}8}9try10{

（一）简介事务的主要特征是，任务要么全部完成，要么都不完成。 （二）概述事务由事务管理器来管理和协调。每个影响事务结果的资源都由一个资源管理器来管理。事务管理器与资源管理器通信，以定义事务的结果。 1、事务处理阶段激活阶段：在这个阶段创建事务。准备阶段：在这个阶段，每个资源管理器都可以定义事务的结果。提交阶段：当所有的资源管理器都成功准备好了，就开始这个阶段。 2、ACID属性事务的特征可以用术语ACID来定...
