int processed = 0; foreach(ListViewItem lvi in listView.Items) { //do stuff if (++processed == 50) break; } or use LINQ foreach( ListViewItem lvi in listView.Items.Cast<ListViewItem>().Take(50)) { //do stuff } or just use a regular for loop (as suggested by @sgriffinusa and @Eric J.) for(int i = 0; i < 50 && i < listView.Items.Count; i++) … Read more
There is no difference. From perldoc perlsyn: The foreach keyword is actually a synonym for the for keyword, so you can use foreach for readability or for for brevity.
foreach (ManagementObject result in results) using(result) { //code here } It’s not normally good practice to assign the variable outside the using block because the resource would be disposed but could stay in scope. It would, however, result in clearer code here because you can nested the using statement against the foreach. EDIT: As pointed … Read more
Its equivalent to for(Iterator<SomeListElement> i = objectWithList.getList().iterator(); i.hasNext(); ) { SomeListElement element = i.next(); //access element here }
Using a nested .each() means that your inner loop is doing one td at a time, so you can’t set the productId and product and quantity all in the inner loop. Also using function(key, val) and then val[key].innerHTML isn’t right: the .each() method passes the index (an integer) and the actual element, so you’d use … Read more
You can’t. Use a for instead for(int i=0; i<list.Count-1; i++) Compare(list[i], list[i+1]);
Declare the $items array outside the loop and use $items[] to add items to the array: $items = array(); foreach($group_membership as $username) { $items[] = $username; } print_r($items);
TL;DR Your best bets are usually a for-of loop (ES2015+ only; spec | MDN) – simple and async-friendly for (const element of theArray) { // …use `element`… } forEach (ES5+ only; spec | MDN) (or its relatives some and such) – not async-friendly (but see details) theArray.forEach(element => { // …use `element`… }); a simple … Read more
