c# 打印一个由泛型列表组成的数组列表

Question

有一个数组列表，它由泛型列表组成，泛型列表的元素是class个变量。我怎样才能打印整个arrayList？我必须使用数组列表、通用列表和 class。逻辑类似于 Array List[Generic Lists[类]].

namespace temp
{
    internal class tempClass
    {
        public string Name;
        public int Number;
    }
    internal class Program
    {
        private static void Main(string[] args)
        {
            string[] Names =  { "a", "b", "c", "d", "e", "f","g", "h", "i", "j", "k", "l", "m","n", "o", "p", "q", "r", "s", "t", "u","v", "w", "x", "y", "z", "z2", "z3" };
            int[] Number = { 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19,20, 21, 22, 23, 24, 25, 26, 27, 28 };
            ArrayList arrayList = new ArrayList();
            int counter = 0;
            List<tempClass> genericList;
            tempClass ClassExample;
            for (int i = 0; i < Names.Length;)
            {
                genericList = new List<tempClass>();
                int elementCount = (int)Math.Pow(2, counter);
                for (int j = 0; j < elementCount; j++)
                {
                    ClassExample = new tempClass();
                    ClassExample.Name = Names[i];
                    ClassExample.Number = Number[i];
                    genericList.Add(ClassExample);
                    i++;
                    if (i == Names.Length) break;
                }
                arrayList.Add(genericList);
                counter++;
            }
            Console.Read();
        }
    }
} ```

Answer 1

下面将为您提供一个单维列表，您可以使用 foreach 打印出每个项目。

List<tempClass> tests = arrayList.ToArray()
                               .Select(obj => (List<tempClass>)obj)
                               .Aggregate((first, second) => { second.AddRange(first.ToArray()); return second; });

foreach(tempClass test in tests)
{
   Console.WriteLine(test.Name);
}

Answer 2

我添加了这个并且成功了，谢谢！

            int counter2 = 0;
            foreach (List<tempClass> temp in arrayList)
            {
                foreach (tempClass temp2 in temp)
                    Console.WriteLine("Name: " + temp2.Name + " Number: " + temp2.Number);
            }
