LINQ - is SkipWhile broken?

Question

I\'m a bit surprised to find the results of the following code, where I simply want to remove all 3s from a sequence of ints:

var sequence = new [] { 1, 1, 2         


        

Answer 1

It's not broken. SkipWhile will only skip items in the beginning of the IEnumerable. Once that condition isn't met it will happily take the rest of the elements. Other elements that later match it down the road won't be skipped.

int[] sequence = { 3, 3, 1, 1, 2, 3 };
var result = sequence.SkipWhile(i => i == 3); 
// Result: 1, 1, 2, 3
