示例
using System; public class Demo { public static void Main(String[] args) { string str1 = "Jacob"; string str2 = "John"; Console.WriteLine("String 1 = "+str1); Console.WriteLine("HashCode of String 1 = "+str1.GetHashCode()); Console.WriteLine("String 2 = "+str2); Console.WriteLine("HashCode of String 2 = "+str2.GetHashCode()); bool res = str1.Contains(str2); if (res) Console.WriteLine("Found!"); else Console.WriteLine("Not found!"); } }
輸出
String 1 = Jacob HashCode of String 1 = -790718923 String 2 = John HashCode of String 2 = -1505962600 Not found!
