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?

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...
}

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");

试试这个。没有任何循环的需要。

string stringToCheck = "text1";
List<string> stringList = new List<string>() { "text1", "someothertext", "etc.." };
if (stringList.Exists(o => stringToCheck.Contains(o)))
{

}

您也可以尝试这个解决方案。

string[] nonSupportedExt = { ".3gp", ".avi", ".opus", ".wma", ".wav", ".m4a", ".ac3", ".aac", ".aiff" };
        
bool valid = Array.Exists(nonSupportedExt,E => E == ".Aac".ToLower());

最简单最简单的方法:

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