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

我使用下面的代码来检查字符串是否包含字符串数组中的任何项:

foreach (string s in stringArray)
{
    if (s != "")
    {
        if (stringToCheck.Contains(s))
        {
            Text = "matched";
        }
    }
}

其他回答

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。

要完成前面的回答,对于IgnoreCase检查,使用:

stringArray.Any(s => stringToCheck.IndexOf(s, StringComparison.CurrentCultureIgnoreCase) > -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

我会使用LINQ,但它仍然可以通过:

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

在我的案例中,上述答案并不奏效。我正在检查数组中的字符串,并将其分配给布尔值。我修改了Anton Gogolev的答案,并删除了Any()方法,并将stringToCheck放在Contains()方法内。

bool isContain = stringArray.Contains(stringToCheck);
⚠️ 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)
