C# 提交/回滚从业务层到存储库层的多个数据库事务调用

我有表示层/业务层/存储库层。所有数据库调用，如select/update/insert/delete，都是在存储库层完成的。业务层检查规则，并根据存储库层进行调用以与数据库交互。我遇到的问题是，每当调用中出现问题时，在业务层回滚事务

我确实参考了一些文章，如和，但我使用transactionscope获得System.Transactions.TransactionException错误

编辑：-

这就是我从业务层调用存储库层的方式

public bool CreatePerson(Model AddPersonToSchool)
    {
        using (TransactionScope scope = new TransactionScope(TransactionScopeOption.Required, TimeSpan.FromSeconds(120)))
        {
            try
            {
                //Check if the person is already created, if not assign him the next Roll call and details

                CreatePersonDetails(Person); //Repository call where SaveChanges() are called.
                //Check the preReq for the subjects

                CreatePersonSubjects(Person); //Repository call where SaveChanges() are called.

                //Check for the Availability of the seats in classes 
                CreateTimeTableForClasses(Person);  //Repository call where SaveChanges() are called.

                LogDetails(Person);

                scope.Complete();
                return true;
            }
            catch (Exception ex)
            {
                scope.Dispose();
                RecordErrorException(ex);
                return false;
            }
        }
    }

这是我收到的错误消息

修复可以简单到将类型值更改为其他值，但我们需要知道您得到的确切错误消息以及不同层如何相互调用。mcve真的可以帮助任何人检查你的问题。如果你需要处理常规存储库的事务，那么从根本上说有些事情是错误的。应该可以通过一个SaveChanges调用提交几乎所有的业务事务，而不管它埋在存储库/UoW层下有多深。也就是说，如果您对代码有问题，请显示代码。这个问题无法回答。看看这个：。您的代码没有透露任何相关细节，我们无法诊断问题。
