Question

我正在研究一个按字母长度排序字典单词的程序。当前代码输出结果。我将结果保存为文本文件时遇到问题。

当前代码

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

class Program
{
static void Main()
{
    // Initialize a List of strings.

    string filePath = "text.txt";
    List<string> linesList = new List<string>();
    string[] fileContent = System.IO.File.ReadAllLines(filePath);
    linesList.AddRange(fileContent);
    // Send the List to the method.
    foreach (string s in SortByLength(linesList))
    {
        Console.WriteLine(s);
    }
 System.IO.File.WriteAllLines("solution.txt",sorted);
}

static IEnumerable<string> SortByLength(IEnumerable<string> e)
{
    // Use LINQ to sort the array received and return a copy.
    var sorted = from s in e
                 orderby s.Length ascending
                 select s;
    return sorted;
}
}

我想你想要File.WriteAllLiness(filePath, SortByLength(linesList));

请注意，您的代码可以简化，因为没有理由像您一样初始化linesList。你可以这样做：

string[] fileContent = File.ReadAllLines(filePath);
var linesList = SortByLength(fileContent);
foreach (string s in lineslist)
{
   //...
}
File.WriteAllLines(filePath, linesList);

C＃ - 将输出写入文本文件
