If 数组语句

Question

不是写多个 if() 语句，有没有办法像下面那样做？

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

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

Answer 1

您可以使用 .Contains()

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

或.Any()

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