foreach循环中的最后一行 [英] Last row in foreach loop
问题描述
有没有办法知道你是否正在查看
foreach循环的最后记录记录，然后设置一个循环计数器，你手动
增量？
foreach（RaceCarCollection中的Racecar赛车）
{
...
如果最后一行做了什么？
}
你可以告诉你收藏了多少物品但是有没有办法来支付
告诉你正在寻找哪一行或者这是最后一行？
谢谢，
Tom
Is there a way to know if you are looking at the last record record of
foreach loop other then setting up a loop counter that you manually
increment?
foreach (Racecar racecar in RaceCarCollection)
{
...
if last row do something?
}
You can tell how many items you have in the collection but is there way to
tell which row you are looking or if this is the last row?
Thanks,
Tom

并非没有反对RaceCarCollection.Count（或.Length）的测试
为什么不使用for循环呢？

Not without counying an test against RaceCarCollection.Count (or .Length)
Why not use a for loop instead?

据我所知。我做过这样的事情：
foreach（int i = 0; i< collection.Count; i ++）
{
object = collection [i];
...
if（i == collection.Count - 1）
做点什么到最后一个对象
}
Not as far as I am aware of. I have done someting like this with:
foreach (int i = 0; i < collection.Count; i++)
{
object = collection[i];
...
if (i == collection.Count - 1)
do something to the last object
}
怀疑它。我总是使用一个计数器变量，并与该集合的长度相比。没什么大不了的。

Doubt it. I''ve always use a counter variable and compared to the length of
the collection. Not a big deal.
