C#中数组的子集

using System;
using System.Linq;

class Program
{
    static void Main()
    {
        int[] numbers = { 1, 2, 3, 4, 5 };

        // 获取数组中大于3的元素
        int[] subset = numbers.Where(x => x > 3).ToArray();

        // 输出子集
        foreach (int num in subset)
        {
            Console.WriteLine(num);
        }
    }
}
