C＃字符串不包含可能吗？ [英] C# string does not contain possible?

问题描述

这就是我要做的。我有一个可读取html的搜寻器，我想知道它何时不包含两个字符串。例如。

This is what I have going on. I have a crawler that reads html, and i'm looking to know when it does not contain two strings. For example.

string firstString = "pineapple"
string secondString = "mango"

string compareString = "The wheels on the bus go round and round"

所以基本上我想知道当第一个字符串和第二个字符串不在compareString中时。

So basically I want to know when the first string and second string are not in the compareString.

感谢所有帮助！

推荐答案

您应该将所有单词放入某种集合或列表中，然后这样称呼它：

You should put all your words into some kind of Collection or List and then call it like this:

var searchFor = new List<string>();
searchFor.Add("pineapple");
searchFor.Add("mango");

bool containsAnySearchString = searchFor.Any(word => compareString.Contains(word));

如果您需要进行案例或与文化无关的搜索，则应这样称呼：

If you need to make a case or culture independent search you should call it like this:

bool containsAnySearchString = 
   searchFor.Any(word => compareString.IndexOf
     (word, StringComparison.InvariantCultureIgnoreCase >= 0);
