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

最简单最简单的方法:

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

试试这个:

不需要使用LINQ

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

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))

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。

您也可以尝试这个解决方案。

string[] nonSupportedExt = { ".3gp", ".avi", ".opus", ".wma", ".wav", ".m4a", ".ac3", ".aac", ".aiff" };
        
bool valid = Array.Exists(nonSupportedExt,E => E == ".Aac".ToLower());
string [] lines = {"text1", "text2", "etc"};

bool bFound = lines.Any(x => x == "Your string to be searched");

如果搜索的字符串与数组'lines'中的任何元素匹配,则bFound设置为true。
