Is there any way to reset a foreach loop to re-iterate through the
collection as if it were starting from the beginning? Namely, if I delete
an item out of a collection, I want to be able to reset the loop.

不，你需要使用for循环或while循环。

我不得不说我不同意for循环遍历集合
然后更改循环中的集合。但是如果你必须这样做，
将for循环包裹在while循环中（while（1 = 1））并且不会结束。
while（1 == 1）
{
foreach（...）
{
if（ item_deleted_from_collection）
{
item_deleted = true;
休息;
}
}
if（not item_deleted）
休息;
}

I have to say I disagree with a for loop that iterates through a collection
and then changes the collection in the loop. However if you must do it,
wrap the for loop inside of a while loop (while (1=1)) that doesn''t end.
while (1==1)
{
foreach (...)
{
if (item_deleted_from_collection)
{
item_deleted = true;
break;
}
}
if (not item_deleted)
break;
}

好奇，你想要完成的最终结果是什么？
也许还有一种更好的方法。

Just curious, what is the end result that you are trying to accomplish?
Perhaps there is a better way.
