Question

我有一个问题是按字母顺序显示名称，反之亦然。当我使用Array.Sort（）时，它首先显示最后一个条目，然后按字母顺序排序。任何帮助，建议将受到高度赞赏。以下是我的代码：

static void Main(string[] args)
    {
       string [] lastName = new string [100];
       string inValue = "", moreData = "";
       int nameCnt = 0;



       while (moreData != "N")
       {
           lastName[nameCnt] = Convert.ToString(inValue);
           nameCnt++;
           Console.Write("Enter Last Name: ");
           inValue = Console.ReadLine();
           Console.Write("Keep going Y/N? ");
           moreData = Console.ReadLine();
           moreData = moreData.ToUpper();
       }
       Console.WriteLine();
       Console.WriteLine(nameCnt + " Last Name(s) Entered");

        Console.WriteLine();
        Console.WriteLine("Names in Ascending Order\n");


            Array.Sort(lastName);
            foreach (string name in lastName)
            {

                lastName[nameCnt] = Convert.ToString(inValue);
                Console.Write(name);
            }

            Console.WriteLine();
            Console.WriteLine("Names in Ascending Order\n");


            Array.Reverse(lastName);
            foreach (string name in lastName)
            {
                lastName[nameCnt] = Convert.ToString(inValue);
                Console.Write(name);
            }

        Console.ReadLine();
    }

误解是如果你在foreach中输入变量nameCnt = 4的四个姓氏在您的安排的4位置，您输入您在变量inValue

中停留的最后一个条目

     foreach (string name in lastName)
        {
             /* Asign position 4 to array inValue input 
             lastName[nameCnt] = Convert.ToString(inValue); */
            Console.WriteLine(name);
        }

删除该行并同时订购您的第一行

    while (moreData != "N")
        {
            Console.Write("Enter Last Name: ");
            inValue = Console.ReadLine();
            lastName[nameCnt] = Convert.ToString(inValue);
            nameCnt++;
            Console.Write("Keep going Y/N? ");
            moreData = Console.ReadLine().ToUpper();
        }

使用Array.Sort（）和Array.Reverse（）对数组Ascending和Descending顺序排序
