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?

⚠️ 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
string strName = "vernie";
string[] strNamesArray = { "roger", "vernie", "joel" };

if (strNamesArray.Any(x => x == strName))
{
   // do some action here if true...
}

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。

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");

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);

你也可以像Anton Gogolev建议的那样,检查stringArray1中的任何项是否与stringArray2中的任何项匹配:

using System.Linq;
if(stringArray1.Any(stringArray2.Contains))

同样,stringArray1中的所有项都匹配stringArray2中的所有项:

using System.Linq;
if(stringArray1.All(stringArray2.Contains))

Try:

String[] val = { "helloword1", "orange", "grape", "pear" };
String sep = "";
string stringToCheck = "word1";

bool match = String.Join(sep,val).Contains(stringToCheck);
bool anothermatch = val.Any(s => s.Contains(stringToCheck));
