从字符串中删除重复的单词

问题描述

我需要从字符串中删除重复的单词.我该怎么做呢?

I need to remove duplicate words from a string. How would I go about doing that?

推荐答案

如果要去掉重复"这个词:

If you want to remove the word "duplicates":

string duplicatesRemoved = RTBstring.Replace("duplicates", "");

;)

删除重复单词的简单(且过于简单)方法是拆分空格字符并使用 LINQ 的 Distinct() 方法:

The easy (and overly simplistic) way to remove duplicate words is to split on the space character and use LINQ's Distinct() method:

string duplicatesRemoved = string.Join(" ", RTBstring.Split(' ').Distinct());

但是，如果您使用的是实际句子(即标点符号会破坏它)，这将不会有用.如果没有明确定义重复的含义以及预期的输入是什么，就很难给出准确的答案.

But this won't work in a useful way if you're working with actual sentences (i.e. punctuation will break it). Without a clear definition of what you mean by duplicates and what the expected input is, it's hard to give an accurate answer.
