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

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)))
{

}

其他回答

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;

试试这个。示例:检查字段是否包含数组中的任何单词。检查字段(someField)是否包含数组中的任何单词。

String[] val = { "helloword1", "orange", "grape", "pear" };

Expression<Func<Item, bool>> someFieldFilter = i => true;

someFieldFilter = i => val.Any(s => i.someField.Contains(s));

⚠️ 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

  stringArray.ToList().Contains(stringToCheck)

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。

This answer checks if a list of words contains one particular word

只需使用LINQ方法:

stringArray.Contains(stringToCheck)
