C# 事务、命令和连接之间的关系是什么？
遵循代码所做的操作： 创建一个事务作用域 将创建并打开一个连接，并在事务中登记它 在步骤1中创建的作用域 使用已打开的连接提交命令 连接已关闭 将创建一个新的事务作用域 相同的连接被打开，这会引发 由新事务创建的新事务中的连接 步骤5中的作用域实例 使用已打开的连接提交命令 第一个事务作用域已完成并被处置，紧接着 那是第二个 在该连接上执行相同的命令会发生什么？即使在调用完成之前连接已关闭，这些命令是否已提交；处置；关于第一个事务范围 我认为，事务根本不由连接管理，即使一个连接被两个事务使用，发送到不同事务的命令也根本不相关，不管它们是使用相同的连接发送到服务器的。我是对的 请遵循以下代码：C# 事务、命令和连接之间的关系是什么？,c#,.net,transactions,transactionscope,sqlconnection,C#,.net,Transactions,Transactionscope,Sqlconnection,遵循代码所做的操作： 创建一个事务作用域 将创建并打开一个连接，并在事务中登记它 在步骤1中创建的作用域 使用已打开的连接提交命令 连接已关闭 将创建一个新的事务作用域 相同的连接被打开，这会引发 由新事务创建的新事务中的连接 步骤5中的作用域实例 使用已打开的连接提交命令 第一个事务作用域已完成并被处置，紧接着 那是第二个 在该连接上执行相同的命令会发生什么？即使在调用完成之前连接已关闭，这些命令是否已提交；处置；关于第一个事务范围 我认为，事务根本不由连接管理，即使一个连接被两个事务使用，发

那代码真的很难读。您不能使用@DJKRAZE重新格式化以正确嵌套作用域吗？@DJKRAZE是的，我在Google中查看了MSDN文档并进行了搜索，但是我在那里找到的信息没有清楚地回答我在这里提出的问题。@usr我编辑了代码，请告诉我您现在是否更清楚。谢谢跟踪消息使代码有点混乱，但它们对于了解正在发生的事情非常重要，我的意思是，了解正在登录到同一文件的事务管理器中c语句的效果。看起来您遗漏了执行第二个命令的调用以及步骤7。@Michael谢谢。代码和日志编辑，没有任何变化，但你是对的，粘贴代码我忘记了那个电话；
