在 C# 中按字母顺序对数组进行排序 [英] Sorting an array alphabetically in C#

问题描述

希望有人能帮忙.我创建了一个可变长度数组，它将接受多个名称输入.我现在想按字母顺序对数组进行排序并将其返回到控制台屏幕.

Hope someone can help. I have created a variable length array that will accept several name inputs. I now want to sort the array in alphabetical order and return that to the console screen.

我认为 Array.Sort(names);会为我做这件事，但我抛出了一个异常.我一直在查看笔记、示例和在线内容，但似乎没有什么与我正在做的事情相匹配.

I thought that Array.Sort(names); would do this for me but I am getting an exception thrown. I have been looking at notes, examples and on-line but nothing seems to match what I am doing.

到目前为止，我已经完成了以下操作.我快要把头发扯掉了！PS 我一直在努力解决这个问题，我已经 30 多岁了，正在努力学习自己，所以请不要只说做你的功课"我哪里出错了.这是一个星期天，我正在努力做额外的工作，但没有笔记来准确地说明这一点

I have done the below so far. I am close to tearing my hair out here! PS I have been trying to figure this out for hours and I am 30+ years old trying to learn myself, so please don't just say "Do your homework" I have tried to resolve this and can not so I need someone to explain where I am going wrong. It is a Sunday and I am trying to do extra work and have no notes to cover this exactly

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;

namespace Student_Array
{
    class Program
    {
        struct Student
        {
            public string Name;
        }

        static void Main(string[] args)
        {
            int numberOfStudents;
            Student[] names;
            string input;

            Console.WriteLine("How many students are there?");
            input = Console.ReadLine();
            numberOfStudents = int.Parse(input);

            names = new Student[numberOfStudents];


            for (int i = 0; i < names.Length; i++)
            {
                Student s;
                Console.WriteLine("Please enter student {0}'s name", (i + 1));
                s.Name = Console.ReadLine();
                names[i] = s;
            }
            ***Array.Sort<Student>(names);***
            for (int i = 0; i < names.Length; i++)
            {

                Console.WriteLine(names[i].Name);
            }
        }
    }
}

推荐答案

这就能解决问题

Array.Sort(names, (x,y) => String.Compare(x.Name, y.Name));
