问题描述

我使用 StreamReader 类从 txt 文件中读取并将其加载到列表中，现在我想选择带有元音的单词并将它们存储到新列表中，以便我可以使用 StreamWriter 只将选定的单词写入新的 txt 文件中

I use StreamReader Class to read from txt file and load it into List, now i want to select on words with vowels and store them into new List so i can use StreamWriter to write only selected words into new txt file

推荐答案

要从给定的单词列表(您检索的)中选择单词，您可以使用 Linq 选择仅包含元音的单词:

To select words from a given list of words (that you retrieve however) you can select the ones that only contain vowels using Linq:

string vowels = "aeiou";
List<string> words = new List<string>();
//words populated
var vowelWords = words.Where( word => word.All( c => vowels.Contains(c) ))
                      .ToList();

如果您只想要包含至少一个元音的单词(从问题中不太清楚):

If you just want words that contain at least a vowel (its not quite clear from the question):

var vowelWords = words.Where( word => word.Any( c => vowels.Contains(c) ))
                      .ToList();

根据评论进行

要选择包含多个元音的单词:

To select words that have more than one vowel:

var vowelWords = words.Where(word => word.Count(c => vowels.Contains(c)) > 1)
                      .ToList();
