TakeWhile, but get the element that stopped it also

Question

I\'d like to use the LINQ TakeWhile function on LINQ to Objects. However, I also need to know the first element that \"broke\" the function, i.e. the first elem

Answer 1

Just for fun:

var a = new[] 
    {
        "two",
        "three",
        "four",
        "five",
    };
  Func predicate = item => item.StartsWith("t");      
  a.TakeWhile(predicate).Concat(new[] { a.SkipWhile(predicate).FirstOrDefault() })
