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。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));

其他回答

使用Array类的Find或FindIndex方法:

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

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

⚠️ 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

只需使用LINQ方法:

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))

  stringArray.ToList().Contains(stringToCheck)

试试这个:

不需要使用LINQ

if (Array.IndexOf(array, Value) >= 0)
{
    //Your stuff goes here
}
