在C＃中按字母顺序排序的数组 [英] Sorting an array alphabetically in C#

问题描述

希望有人可以提供帮助。
我创建了一个可变长度的数组，将接受若干名输入。
我现在要按照字母顺序排序的数组，并返回到控制台屏幕。

我认为的Array.Sort（地名）;会做这对我来说，但我得到一个的异常。我一直在看笔记，例子和上线，但似乎没有任何匹配我在做什么。

我也做了以下为止。我靠近这里撕裂我的头发了！
PS我一直在试图弄清楚这一点了几个小时，我30多岁，想学我自己，所以请不要只说做好功课我试图解决这个，不能，所以我需要有人来解释我要去的地方错了。
这是一个星期天，我试图做额外的工作，没有任何票据，以支付这正是

 使用系统;
使用System.Collections.Generic;
使用System.Linq的;
使用System.Text;命名空间Student_Array
{
    类节目
    {
        学生结构
        {
            公共字符串名称;
        }        静态无效的主要（字串[] args）
        {
            INT numberOfStudents;
            学生[]的名称;
            字符串输入;            Console.WriteLine（有多少个学生？）;
            输入=到Console.ReadLine（）;
            numberOfStudents = int.Parse（输入）;            名称=新的学生[numberOfStudents]
            的for（int i = 0; I＆LT; names.Length;我++）
            {
                学生们;
                Console.WriteLine（请输入学生{0}名字，第（i + 1））;
                s.Name =到Console.ReadLine（）;
                名称由[i] = S;
            }
            ***的Array.Sort＆LT;的Student GT;（地名）; ***
            的for（int i = 0; I＆LT; names.Length;我++）
            {                Console.WriteLine（名称[I] .Name点）;
            }
        }
    }
}
 

解决方案

这应该做的伎俩

 的Array.Sort（姓名，（X，Y）=＆GT;的String.Compare（x.Name，y.Name））;
 

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.

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.

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);
            }
        }
    }
}

解决方案

This shall do the trick

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