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

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;

⚠️ 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

我在控制台应用程序中使用以下命令检查参数

var sendmail = args.Any( o => o.ToLower() == "/sendmail=true");

使用Array类的Find或FindIndex方法:

if(Array.Find(stringArray, stringToCheck.Contains) != null) 
{ 
}
if(Array.FindIndex(stringArray, stringToCheck.Contains) != -1) 
{ 
}

在我的案例中,上述答案并不奏效。我正在检查数组中的字符串,并将其分配给布尔值。我修改了Anton Gogolev的答案,并删除了Any()方法,并将stringToCheck放在Contains()方法内。

bool isContain = stringArray.Contains(stringToCheck);

The question asked is "how can I check if a sentence contains any word from a list of words?"

只需使用LINQ方法:

stringArray.Contains(stringToCheck)

我使用下面的代码来检查字符串是否包含字符串数组中的任何项:

foreach (string s in stringArray)
{
    if (s != "")
    {
        if (stringToCheck.Contains(s))
        {
            Text = "matched";
        }
    }
}
