Can I select just the first ten rows and also skip the first ten rows of a foreach?
I am running a process like this:
foreach (var x in App.cardSetWithWordCount.Select((r, i) =>
new { Row = r, Index = i }))
{
// Some code here
}
The code inside this routine takes a long time and what I would like to do is to run this for the first ten rows and then run it again for the remaining rows. Something like this:
// just the first ten rows in App.cardSetWithWordCount
foreach (var x in App.cardSetWithWordCount.Select((r, i) =>
new { Row = r, Index = i }))
{
// Some code here
}
then
// everything else except ten rows in App.cardSetWithWordCount
foreach (var x in App.cardSetWithWordCount.Select((r, i) =>
new { Row = r, Index = i }))
{
// Some code here
}
Is there a way to select just the first ten rows and also a way to skip the first ten that I could apply to the foreach?

as far as i understand you can not do. if i understand correctly. You want to change the list during iteration?

you can add a where a Where() statement like so.Where(x => x.r <=10)

Consider using MoreLINQ'sSegment.

You also need to put a.ToList()at the end.

You can use
App.cardSetWithWordCount.Take(10)
To get the first 10, and then
App.cardSetWithWordCount.Skip(10)
To skip the first ten
Or I guess you could do it the old fashioned way, iterating over App.cardSetWithWordCount with a for loop.
