从C#中的加权列表中选择x个随机元素(无需替换)

Random random = new Random();
List<int> weights = new List<int>() { 1, 2, 3, 4, 5 };
int numberOfElements = 10;
int x = random.Next(numberOfElements);
int chosenElement = weights[x - 1];

using System;
using System.Collections.Generic;
using System.Linq;

class RandomWeightedList
{
    public static void Main()
    {
        Random random = new Random();
        List<int> weights = new List<int>() { 1, 2, 3, 4, 5 };
        int numberOfElements = 10;
        int x = random.Next(numberOfElements);
        int chosenElement = weights[x - 1];

        List<int> result = new List<int>();
        for (int i = 0; i < numberOfElements; i++)
        {
            int randomIndex = random.Next(weights.Count);
            int element = weights[randomIndex];
            result.Add(element);
            weights.RemoveAt(randomIndex);
        }

        Console.WriteLine("Chosen element: " + chosenElement);
        Console.WriteLine("Randomly chosen elements: " + string.Join(", ", result));
    }
}
