If Statement With Array

Question

Instead of writing multiple if() statements, is there a way to do something like the below?

string redlight = "Larry";
string[] names = { "Joe", "Jack", "Bob", "Larry", "Alpha", "Mick", "Lance", "Ben" };

if (redlight == names)
    Console.WriteLine("It's in the array");

How strict do you need to be? if redlight = "joe", do you want to match "Joe" in the array? — Joel Coehoorn

You can use either .Contains()

if (names.Contains(redlight))
    Console.WriteLine("It's in the array");
else
    Console.WriteLine("It's not in the array");

or .Any()

if (names.Any(x=>x==redlight))
   Console.WriteLine("It's in the array");
else
   Console.WriteLine("It's not in the array");

What does x represent in the .Any() example

sujith karivelil Over a year ago

It will internally iterate the collection so x will be an item of the collection, you can read more about .Any() from here
