var numbers = new[] {1,2,3,4,5};

var isNotEmpty = numbers.Any();
Console.WriteLine(isNotEmpty); //True

var anyNumberIsOne = numbers.Any(n => n == 1);
Console.WriteLine(anyNumberIsOne); //True

var anyNumberIsSix = numbers.Any(n => n == 6);
Console.WriteLine(anyNumberIsSix); //False    

var anyNumberIsOdd = numbers.Any(n => (n & 1) == 1);
Console.WriteLine(anyNumberIsOdd); //True

var anyNumberIsNegative = numbers.Any(n => n < 0);
Console.WriteLine(anyNumberIsNegative); //False
