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?

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

  stringArray.ToList().Contains(stringToCheck)

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());

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

试试这个。没有任何循环的需要。

string stringToCheck = "text1";
List<string> stringList = new List<string>() { "text1", "someothertext", "etc.." };
if (stringList.Exists(o => stringToCheck.Contains(o)))
{

}

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:

不需要使用LINQ

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