在C＃中的交易 [英] Transactions in C#

问题描述

首先，这不会是一个关于数据库事务职位。我想知道更多关于 TransactionModel 在.NET 2.0及更高版本。由于我对.NET 3.5较新的型号apprechiated发展。

First of all, this will not be a post about Database Transactions. I want to know more about the TransactionModel in .NET 2.0 and higher. Since I am developing against .NET 3.5 newer models are apprechiated.

现在，我想acheive什么是一样的东西以下

Now, what I would like to acheive is something like the following

    public void Withdraw(double amount)
    {
        using (TransactionScope scope = new TransactionScope())
        {
            Money -= amount;

            if (Money > 0)
                scope.Complete();
        }
    }

这将意味着，当这些钱是小于0 ，里面的一切的TransactionScope 应该是RolledBack，然而，事实并非如此。

Which would mean that when the Money is less than 0, everything inside the TransactionScope should be RolledBack, however, it's not.

一个简单的测试，为后面

A simple test as followed

        ImportantObject obj = new ImportantObject(1);

        Console.WriteLine(obj.Money);

        obj.Withdraw(101);

        Console.WriteLine(obj.Money);

前提是Stadard金额为100。

Provided that the Stadard Money amount is 100.

难道我错过这里的东西，或者这是不是交易应如何工作的？ ？什么都采用这种模式的性能损失。

Did I miss something here or is this not how the transactions should work? And what are the performance losses using this model?
