c# - Any in-built method to only know if two lists are different? -

-

i have compare 2 lists , only know if contain same values or not. not intend differences.

what best way achieve in c#?

i know can loop lists want know if theres in-built linq/extenstion method achieve provides better performance. did try except/intersect, don't know if suitable ones achieve this.

update: lists won't have duplicates within them.

how want handle duplicates? example, count { 2, 1, 1 } being same { 1, 2 }? (i'm assuming order irrelevant... otherwise use sequenceequal.)

assuming care "sets" effectively, here 2 options:

a quick , dirty way:

if (!list1.except(list2).any() && !list2.except(list1).any())

a cleaner way:

var set = new hashset<int>(list1); // adjust case accordingly if (set.setequals(list2)) {     // lists equal }

one thing consider: if you're interested in treating them sets, might want use set representation start with, instead of list...

javascript - Enclosure Memory Copies -

(or else how bar method keep myclass variables straight on per instance basis?) now (2) question i'm after. since inner foo method doesn't use in myclass enclosure natural qustion is: javascript smart enough not keep myclass enclosure in memory use of foo? this depend entirely on implementation not language. naive implementations keep far more around others. answer true e.g. v8 (chrome's js engine) may not true spider...

-
example preg_replace('/\{[a-za-z.,\(\)0-9]+\}/', 'replaced', 'lorem ipsum dolor sit {tag1({tag2()})}, consectetur adipiscing elit.'); the result: lorem ipsum dolor sit {tag1(replaced)}, consectetur adipiscing elit. question as can see "tag2" has been replaced, want replace "tag1" know how can this? (in cases might this: {tag1({tag2({tag3()})})}) , on.) btw using preg_replace_callback, easier show preg_replace here site can test code: http://www.spaweditor.com/scripts/regex/index.php you need add curly braces character set. here's pattern used: /\{[a-za-z.,\(\)\{\}0-9]+\}/ and here result: "lorem ipsum dolor sit replaced, consectetur adipiscing elit."
