Question

How do I retrieve all elements after the first one not starting with a "-" using linq?

var arr = new[] {"-s1", "-s2", "va", "-s3", "va2", "va3"};
var allElementsAfterVA = from a in arr where ???? select a;

I want allElementsAfterVA to be "-s3", "va2", "va3"

Answer 1

To find all of the arguments after the first that does NOT start with “-“, you can do:

var elementsAfterFirstNonDash = arr.SkipWhile(i => i[0] != '-').Skip(1);

This finds “va”, then skips it via Skip(1). The rest of the arguments will be returned.
