C# 程序在 C# 中打印给定整数数组的所有不同元素
csharpprogrammingserver side programming更新于 2025/9/18 23:39:00
我们设置了一个数组和一个字典来获取不同元素。
int[] arr = {
88,
23,
56,
96,
43
};
var d = new Dictionary < int, int > ();
字典集合允许我们获取列表的键和值。
以下是显示给定整数数组的不同元素的代码 −
示例
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
88 occurred 1 time 23 occurred 1 time 56 occurred 1 time 96 occurred 1 time 43 occurred 1 time
