c# - Tips of Linq expression Any to determine if a collection is Empty

When you are @ the linq expression, you may wonder why it is not offered to you to do the empty() method which can tell if a collection is empty?
well, Surely that Microsoft has someway to allow you to achieve it.
the key lies in the Any()'s void argument variant. 
Here is the code. 

    class Program
    {
        private static void Main(string[] args)
        {
            IEnumerable<string> strings = new List<string>()
                                              {
                                                  "A",
                                                  "B",
                                                  "C",
                                              };
            if (!strings.Any())
            {
                Console.WriteLine("IEnumerable is empty!");
            }
            else
            {
                Console.WriteLine("IEnumerale is not empty!");
            }

            IEnumerable<string> strings2 = new List<string>();
            if (!strings2.Any())
            {
                Console.WriteLine("IEnumerable is empty!");
            }
            else
            {
                Console.WriteLine("IEnumerable is not empty");
            }
        }
    }

 

So you'd better stop to use the slow/stupid Count() > 0 predicate to find if an Collection is empty or not..
