如何按C＃中的字符串长度对字符串数组进行排序 [英] How Do I Sort String Array By Length Of Strings In C#

问题描述

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

namespace Name
{
    class LCS
    {
        int n;
        static void Main()
        {
            LCS obj = new LCS();
            obj.arrays();
            Console.ReadLine();
        }
        public void arrays()
        {
            Console.WriteLine("Enter how many strings you want to enter:-");
            n = Int32.Parse(Console.ReadLine());
            List<string> sampleList = new List<string>();
            Console.WriteLine("Enter  " + n + " strings");
            for (int i = 0; i < n; i++)
            {
                sampleList.Add(Console.ReadLine());
            }     
    }
}

推荐答案

您可以使用LINQ：

You can use LINQ for that:

sampleList = sampleList.OrderBy(s => s.Length).ToList();

就像我说的有几个这样做的方法。当然，ProgramFOX的LINQ解决方案是正确的。所以这是使用 List.Sort方法 [ ^ ]：

Like I said there are several ways to do this. And of course ProgramFOX's solution with LINQ is correct. So here is an alternative using List.Sort method[^]:

sampleList.Sort((x,y) => x.Length - y.Length);

好​​处是您没有创建List的新实例。

The benefit is you are not creating a new instance of List.
