如何检查字符串是否包含单词的所有字符

问题描述

我想检查一个字符串是否包含给定单词的所有字符，例如:

I wish to check if a string contains a all of the characters of a word given, for example:

var inputString = "this is just a simple text string";

说我有这个词:

var word = "ts";

现在应该选择包含和的单词:

Now it should pick out the words that contains and :

这就是我正在从事的工作:

This is what I am working on:

var names = Regex.Matches(inputString, @"\S+ts\S+",RegexOptions.IgnoreCase);

但是，这并没有给我回我喜欢的词.如果我只喜欢这样的字符，它将把所有包含的单词还给我.如果我使用的是而不是，它将带给我单词.

however this does not give me back the words I like. If I had like just a character like , it would give me back all of the words that contains . If I had instead of , it would give me back the word .

关于它如何工作的任何想法?

Any idea of how this can work ?

推荐答案

这是LINQ解决方案，与正则表达式相比，它在眼睛上更自然.

Here is a LINQ solution which is easy on the eyes more natural than regex.

var testString = "this is just a simple text string";
string[] words = testString.Split(' ');
var result = words.Where(w => "ts".All(w.Contains));

结果是:
