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

也许是这样的:

string stringToCheck = "text1text2text3";
string[] stringArray = new string[] { "text1" };
if (Array.Exists<string>(stringArray, (Predicate<string>)delegate(string s) { 
    return stringToCheck.IndexOf(s, StringComparison.OrdinalIgnoreCase) > -1; })) {
    Console.WriteLine("Found!");
}

其他回答

⚠️ 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...
}

使用Array类的Find或FindIndex方法:

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

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

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));

最简单最简单的方法:

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

一个不需要任何LINQ的简单解决方案:

String.Join(",", array).Contains(Value + ",");
