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

你可以这样做:

string stringToCheck = "text1";
string[] stringArray = { "text1", "testtest", "test1test2", "test2text1" };
foreach (string x in stringArray)
{
    if (stringToCheck.Contains(x))
    {
        // Process...
    }
}

也许你正在寻找一个更好的解决方案……参考Anton Gogolev使用LINQ的答案。

其他回答

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!");
}

试试这个

string stringToCheck = "text1text2text3";
string[] stringArray = new string[] { "text1" };

var t = lines.ToList().Find(c => c.Contains(stringToCheck));

它将返回您正在查找的文本的第一个出现的行。

⚠️ 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);

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));

public bool ContainAnyOf(string word, string[] array) 
    {
        for (int i = 0; i < array.Length; i++)
        {
            if (word.Contains(array[i]))
            {
                return true;
            }
        }
        return false;
    }
