Title Body

Let's say I need to compare if string x is "A", "B", or "C". With Python, I can use in operator to check this easily. if x in ["A","B","C"]: do something With C#, I can do if (String.Compare(x, "A", StringComparison.OrdinalIgnoreCase) || ...) do something Can it be something more similar to Python? ADDED I needed to add System.Linq in order to use case insensitive Contain(). using System; using System.Linq; using System.Collections.Generic; class Hello { public static void Main() { var x = "A"; var strings = new List<string> {"a", "B", "C"}; if (strings.Contains(x, StringComparer.OrdinalIgnoreCase)) { Console.WriteLine("hello"); } } } or using System; using System.Linq; using System.Collections.Generic; static class Hello { public static bool In(this string source, params string[] list) { if (null == source) throw new ArgumentNullException("source"); return list.Contains(source, StringComparer.OrdinalIgnoreCase); } public static void Main() { string x = "A"; if (x.In("a", "B", "C")) { Console.WriteLine("hello"); } } }
