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

⚠️ 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);

其他回答

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))

试试这个:

不需要使用LINQ

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

使用Array类的Find或FindIndex方法:

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

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

只需使用LINQ方法:

stringArray.Contains(stringToCheck)

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。
