使用c#检查字符串数组中是否包含字符串

我想使用c#检查字符串值是否包含字符串数组中的单词。例如,

string stringToCheck = "text1text2text3";

string[] stringArray = { "text1", "someothertext", etc... };

if(stringToCheck.contains stringArray) //one of the items?
{

}

我如何检查字符串值'stringToCheck'是否包含数组中的一个词?

当前回答

⚠️ Note: this does not answer the question asked
The question asked is "how can I check if a sentence contains any word from a list of words?"
This answer checks if a list of words contains one particular word

只需使用LINQ方法:

stringArray.Contains(stringToCheck)

其他回答

LINQ:

arrray。Any(x => word.Equals(x));

这是为了查看数组是否包含单词(精确匹配)。使用. contains作为子字符串，或者其他任何你可能需要应用的逻辑。

string [] lines = {"text1", "text2", "etc"};

bool bFound = lines.Any(x => x == "Your string to be searched");

如果搜索的字符串与数组'lines'中的任何元素匹配，则bFound设置为true。

使用LINQ和方法组将是最快和更紧凑的方法。

var arrayA = new[] {"element1", "element2"};
var arrayB = new[] {"element2", "element3"};

if (arrayB.Any(arrayA.Contains)) 
    return true;

要完成前面的回答，对于IgnoreCase检查，使用:

stringArray.Any(s => stringToCheck.IndexOf(s, StringComparison.CurrentCultureIgnoreCase) > -1)

最简单最简单的方法:

bool bol = Array.Exists(stringarray, E => E == stringtocheck);
