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

我会使用LINQ,但它仍然可以通过:

new[] {"text1", "text2", "etc"}.Contains(ItemToFind);

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");

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));

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。

方法如下:

using System.Linq;

if(stringArray.Any(stringToCheck.Contains))

/* or a bit longer: (stringArray.Any(s => stringToCheck.Contains(s))) */

这个函数检查stringToCheck是否包含stringArray的子字符串。如果你想确保它包含所有的子字符串,将Any更改为all:

if(stringArray.All(stringToCheck.Contains))

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)
