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"

Syntax of LINQ FIRST () method The syntax of the first method to get the first element from the list is: int result = objList. First();
The Take operator is used to return a given number of elements from an array and the Skip operator skips over a specified number of elements from an array. Skip, skips elements up to a specified position starting from the first element in a sequence.
The First() method returns the first element of a collection, or the first element that satisfies the specified condition using lambda expression or Func delegate. If a given collection is empty or does not include any element that satisfied the condition then it will throw InvalidOperation exception.
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.
