写随机点名的程序，抽取三个人名，并且进行控制台输出。 1班有八个人，"张三","李四","王五","赵六","孙七","周八","吴九","郑十" 2班有八个人，"张三2","李四2","王五2","赵六2","孙七2","周八2","吴九2","郑十2"

可以使用Random类来实现随机点名程序，具体实现如下：

using System;

namespace RandomName
{
    class Program
    {
        static void Main(string[] args)
        {
            string[] class1 = { "张三", "李四", "王五", "赵六", "孙七", "周八", "吴九", "郑十" };
            string[] class2 = { "张三2", "李四2", "王五2", "赵六2", "孙七2", "周八2", "吴九2", "郑十2" };

            Random random = new Random();
            int index1 = random.Next(0, class1.Length);
            int index2 = random.Next(0, class2.Length);
            int index3 = random.Next(0, class1.Length);

            Console.WriteLine("抽取的三个人名为：");
            Console.WriteLine(class1[index1]);
            Console.WriteLine(class2[index2]);
            Console.WriteLine(class1[index3]);

            Console.ReadKey();
        }
    }
}

以上代码中，我们首先定义了两个班级的学生名单，然后使用Random类生成三个随机数，分别对应三个被抽取的学生的下标。最后将这三个学生名字输出到控制台上。
