Question

我有两个单词列表。

  List<string> mainList = new List<string> {"blue", "green", "mother", "black", "gray"};
  List<string> checkList = new List<string> {"mother", "green", "father", "black", "gray"};

然后我想从第一个列表中取一个随机元素......

  Random rand = new Random();
  string iGenerated = mainList[rand.Next(mainList.Count)];

然后检查此字符串是否也属于第二个列表。我不确定我究竟能做到这一点。我想到了这样的......这是正确的方法吗？

 if checkList.Contains(iGenerated) bool strInArray = true;
 else bool strInArray = false;

Answer 1

以下是我在Console应用程序中的程序：

char buf[128];
count(buf, file_name);
printf("%s", buf);

Answer 2

使用Contains()的{{1}}

可以实现您尝试做的事情

List

结果：

using System;
using System.Collections.Generic;

public class Program
{
    public static void Main()
    {
        List<string> mainList = new List<string> { "blue", "green", "mother", "black", "gray" };
        List<string> checkList = new List<string> { "mother", "green", "father", "black", "gray" };

        Random r = new Random();

        // Run five random tests
        for (int i = 0; i < 5; i++)
        {
            string mainListItem = mainList[r.Next(0, mainList.Count)];
            Console.WriteLine(checkList.Contains(mainListItem)
                              ? "{0} found in checkList"
                              : "{0} not found in checkList", mainListItem);
        }
    }
}
