从C#中的字典创建一个随机列表，其中包括一个特定的选定项目

using System;
using System.Collections.Generic;

Dictionary<int, string> dictionary = new Dictionary<int, string>();
dictionary.Add(1, "项目1");
dictionary.Add(2, "项目2");
dictionary.Add(3, "项目3");
// 添加其他项目...

List<int> keys = new List<int>(dictionary.Keys);

Random random = new Random();

List<string> randomList = new List<string>();

int selectedKey = random.Next(1, dictionary.Count + 1); // 生成一个介于1和字典大小之间的随机数
randomList.Add(dictionary[selectedKey]);

using System;
using System.Collections.Generic;

class Program
{
    static void Main(string[] args)
    {
        Dictionary<int, string> dictionary = new Dictionary<int, string>();
        dictionary.Add(1, "项目1");
        dictionary.Add(2, "项目2");
        dictionary.Add(3, "项目3");
        // 添加其他项目...

        List<int> keys = new List<int>(dictionary.Keys);

        Random random = new Random();

        List<string> randomList = new List<string>();

        int selectedKey = random.Next(1, dictionary.Count + 1);
        randomList.Add(dictionary[selectedKey]);

        Console.WriteLine("随机列表中的选定项目：");
        foreach (string item in randomList)
        {
            Console.WriteLine(item);
        }
    }
}
