blocks|key|960048|text|我认为上面的答案有缺陷，它挂断了主线，在大多数情况下，它是危险的。您应该为这个延迟任务启动一个新线程，在线程进程中，休眠30秒，然后在第二个线程中完成工作。|type|unstyled|depth|inlineStyleRanges|entityRanges|data|960049|entityMap^0|0^^$0|@$1|2|3|4|5|6|7|D|8|@]|9|@]|A|$]]|$1|B|3|-4|5|6|7|E|8|@]|9|@]|A|$]]]|C|$]]

I think above answer has flaw, it hangs up the main thread , in most case, it is dangerous.
You should start a new thread for this delay task, in the thread proc, sleep 30 seconds and then do the work in second thread.

blocks|key|5075759|text|使用Thread.Sleep(5000)来挂起一个线程5秒钟，而不是你的代码-它有几个逻辑错误。|type|unstyled|depth|inlineStyleRanges|offset|length|style|CODE|entityRanges|data|5075760|在执行该行时，present将是DateTime.Now的值，而add30Seconds将是该行执行时DateTime.Now的值加上5秒。|5075761|这些变量不会更新，也不会更改它们的值。|BOLD|5075762|这意味着present永远不会对add30Seconds执行==操作。|5075763|entityMap^0|2|I|0|7|7|G|C|W|C|1F|C|0|4|4|0|4|7|G|C|U|2|0^^$0|@$1|2|3|4|5|6|7|O|8|@$9|P|A|Q|B|C]]|D|@]|E|$]]|$1|F|3|G|5|6|7|R|8|@$9|S|A|T|B|C]|$9|U|A|V|B|C]|$9|W|A|X|B|C]|$9|Y|A|Z|B|C]]|D|@]|E|$]]|$1|H|3|I|5|6|7|10|8|@$9|11|A|12|B|J]]|D|@]|E|$]]|$1|K|3|L|5|6|7|13|8|@$9|14|A|15|B|C]|$9|16|A|17|B|C]|$9|18|A|19|B|C]]|D|@]|E|$]]|$1|M|3|-4|5|6|7|1A|8|@]|D|@]|E|$]]]|N|$]]

Use <code>Thread.Sleep(5000)</code> in order to suspend a thread for 5 seconds, instead of your code - it has several logical errors.

<code>present</code> will be the value of <code>DateTime.Now</code> when that line is executed, and <code>add30Seconds</code> will be the value of <code>DateTime.Now</code> plus 5 seconds when that line is executed.

These variables will not update and will not change their values.

This means that <code>present</code> will never be <code>==</code> to <code>add30Seconds</code>.

blocks|key|3462341|text|那么你的要求是等待30秒后再借记吗？如果是这样的话，看看Timer类。您可以将间隔设置为30秒，并在触发时执行您的操作。|type|unstyled|depth|inlineStyleRanges|entityRanges|data|3462342|http://www.dijksterhuis.org/using-timers-in-c/|offset|length|3462343|然而，30秒的等待似乎是一个可怕的长时间？这是课程作业要求吗？|3462344|entityMap|0|LINK|mutability|MUTABLE|url^0|0|0|1A|0|0|0^^$0|@$1|2|3|4|5|6|7|O|8|@]|9|@]|A|$]]|$1|B|3|C|5|6|7|P|8|@]|9|@$D|Q|E|R|1|S]]|A|$]]|$1|F|3|G|5|6|7|T|8|@]|9|@]|A|$]]|$1|H|3|-4|5|6|7|U|8|@]|9|@]|A|$]]]|I|$J|$5|K|L|M|A|$N|C]]]]

SO your requirement it wait 30 seconds and then debit? If so, look at the Timer class. You can set the interval to 30 seconds, and when triggered perform your action.

<a href="http://www.dijksterhuis.org/using-timers-in-c/" rel="nofollow">http://www.dijksterhuis.org/using-timers-in-c/</a>

30 seconds does seem an awful long time though to wait? Is this a coursework requirement?

blocks|key|5075800|text|在您的代码中实际上没有任何东西在等待。您立即执行检查，它将始终为真。事实上，除非你非常幸运，否则你几乎永远不会达到那个确切的时间。|type|unstyled|depth|inlineStyleRanges|entityRanges|data|5075801|你可以用计时器来处理这个。|5075802|var+completed+=+false;

There's nothing actually waiting in your code. You're immediately executing the check and it will always be true. In fact, unless you get extremely lucky, you'll almost never hit that exact time.

You could use a timer with this.

<pre><code>var completed = false;
var timer = new System.Timers.Timer(30 * 1000);
timer.Elapsed += (o,e) =&gt; 
 {
 b.Debit(amount);
 completed = true;
 this.Status = TransactionStatus.Complete;
 };
timer.Start();
this.Status = TransactionStatus.Pending;

while (!completed) ;
</code></pre>

NOTE There's no error-checking if the debit hangs or times out.

blocks|key|5075871|text|你也可以使用下面的代码：|type|unstyled|depth|inlineStyleRanges|entityRanges|data|5075872|DateTime+present+=+DateTime.Now;
DateTime+addFiveSeconds+=+DateTime.Now.AddSeconds(10);

You can use this code too:

<pre><code>DateTime present = DateTime.Now;
DateTime addFiveSeconds = DateTime.Now.AddSeconds(10);

while (DateTime.Now.TimeOfDay.TotalSeconds &lt;= addFiveSeconds.TimeOfDay.TotalSeconds)
{
 this.Status = TransactionStatus.Pending; 
} 
b.Debit(amount);
this.Status = TransactionStatus.Complete;
</code></pre>

blocks|key|3462597|text|添加到代码开头：|type|unstyled|depth|inlineStyleRanges|entityRanges|data|3462598|使用|3462599|System.Threading;++++++++++++++++//+allows+use+of+sleep+time|code-block|syntax|javascript|3462600|在你的代码中插入：|3462601|Thread.Sleep(5000);+++++++++++++//+Pause+5+seconds,+where+you+need,+delay+5+seconds|3462602|entityMap^0|0|0|0|0|0^^$0|@$1|2|3|4|5|6|7|O|8|@]|9|@]|A|$]]|$1|B|3|C|5|6|7|P|8|@]|9|@]|A|$]]|$1|D|3|E|5|F|7|Q|8|@]|9|@]|A|$G|H]]|$1|I|3|J|5|6|7|R|8|@]|9|@]|A|$]]|$1|K|3|L|5|F|7|S|8|@]|9|@]|A|$G|H]]|$1|M|3|-4|5|6|7|T|8|@]|9|@]|A|$]]]|N|$]]

add to start of code:

using 

<pre><code>System.Threading; // allows use of sleep time
</code></pre>

In your code insert:

<pre><code>Thread.Sleep(5000); // Pause 5 seconds, where you need, delay 5 seconds
</code></pre>

I'm trying to translate this into C# code:

Wait 5 seconds and then debit the bank account.

I've got a feeling I'm close... but this isn't working. Am I doing this the right way?

<pre><code> public override void Process(BankAccount b, decimal amount)
 {
 DateTime present = DateTime.Now;
 DateTime addFiveSeconds = DateTime.Now.AddSeconds(5);

 if (present != addFiveSeconds)
 {
 this.Status = TransactionStatus.Pending;
 }
 else
 {
 b.Debit(amount);
 this.Status = TransactionStatus.Complete;
 }
 }
</code></pre>
