In PHP I can do this:
$list = array("element1", "element2"); foreach ($list as $index => $value) { // do stuff } In C# i can write:
var list = new List<string>(){ "element1", "element2" }; foreach (var value in list) { // do stuff () } But how can I access the index-value in the C# version?
Found multiple solutions on: foreach with index
I liked both JarredPar's solution:
foreach ( var it in list.Select((x,i) => new { Value = x, Index=i }) ) { // do stuff (with it.Index) } and Dan Finch's solution:
list.Each( ( str, index ) => { // do stuff } ); public static void Each<T>( this IEnumerable<T> ie, Action<T, int> action ) { var i = 0; foreach ( var e in ie ) action( e, i++ ); } I chose Dan Finch's method for better code readability.
(And I didn't need to use continue or break)
I'm not sure it's possible to get the index in a foreach. Just add a new variable, i, and increment it; this would probably be the easiest way of doing it...
int i = 0; var list = new List<string>(){ "element1", "element2" }; foreach (var value in list) { i++; // do stuff () } If you have a List, then you can use an indexer + for loop:
var list = new List<string>(){ "element1", "element2" }; for (int idx=0; idx<list.Length; idx++) { var value = list[idx]; // do stuff () } If you want to access index you should use for loop
for(int i=0; i<list.Count; i++) { //do staff() } i is the index
