如何检查字符串是否包含单词的所有字符 [英] How to check if a string contains all of the characters of a word

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 t 和 s 的单词:

Now it should pick out the words that contains t and s:

这只是字符串

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 t 这样的字符，它将把所有包含 t 的单词还给我.如果我使用的是 st 而不是 ts ，它将带给我单词 just .

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

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:

此
只是
字符串

this
just
string
