我们设置了一个数组和一个字典来获取不同的元素。
int[] arr = { 88, 23, 56, 96, 43 }; var d = new Dictionary < int, int > ();
字典集合使我们能够获取列表的键和值。
以下是显示给定整数数组的不同元素的代码-
using System; using System.Collections.Generic; namespace Demo { public class Program { public static void Main(string[] args) { int[] arr = { 88, 23, 56, 96, 43 }; var d = new Dictionary < int, int > (); foreach(var res in arr) { if (d.ContainsKey(res)) d[res]++; else d[res] = 1; } foreach(var val in d) Console.WriteLine("{0} occurred {1} time", val.Key, val.Value); } } }
输出结果
88 occurred 1 time 23 occurred 1 time 56 occurred 1 time 96 occurred 1 time 43 occurred 1 time
