C# 拆分数组

Question

我需要在中点将一个不确定大小的数组拆分为两个单独的数组。

数组是使用 ToArray() 从字符串列表生成的。

        public void AddToList ()
        {
            bool loop = true;
            string a = "";

            Console.WriteLine("Enter a string value and press enter to add it to the list");
            while (loop == true)
            {
                a = Console.ReadLine();

                if (a != "")
                {
                    mylist.Add(a);
                }
                else
                {
                    loop = false;
                }
            }

        }

        public void ReturnList()
        {
            string x = "";
            foreach (string number in mylist)
            {
                x = x + number + " ";
            }
            Console.WriteLine(x);
            Console.ReadLine();
        }

    }

    class SplitList
    {
        public string[] sTop;
        public string[] sBottom;

        public void Split(ref UList list)  
        {
            string[] s = list.mylist.ToArray();

            //split the array into top and bottom halfs

        }
    }

    static void Main(string[] args)
    {
        UList list = new UList();
        SplitList split = new SplitList();

        list.AddToList();
        list.ReturnList();

        split.Split(ref list);
    }
}

您可以使用以下方法将数组拆分为 2 个单独的数组

public void Split<T>(T[] array, int index, out T[] first, out T[] second) {
  first = array.Take(index).ToArray();
  second = array.Skip(index).ToArray();
}

public void SplitMidPoint<T>(T[] array, out T[] first, out T[] second) {
  Split(array, array.Length / 2, out first, out second);
}
