Using C# to check if string contains a string in string array

Question

I want to use C# to check if a string value contains a word in a string array. For example,

string stringToCheck = "text1text2text3";  string[] stringArray = { "text1", "someothertext", etc... };  if(stringToCheck.contains stringArray) //one of the items? {  } 

How can I check if the string value for 'stringToCheck' contains a word in the array?

Answer 1

Here's how:

using System.Linq;  if(stringArray.Any(stringToCheck.Contains))  /* or a bit longer: (stringArray.Any(s => stringToCheck.Contains(s))) */ 

This checks if stringToCheck contains any one of substrings from stringArray. If you want to ensure that it contains all the substrings, change Any to All:

if(stringArray.All(stringToCheck.Contains)) 

Answer 2

here is how you can do it:

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

UPDATE: May be you are looking for a better solution.. refer to @Anton Gogolev's answer below which makes use of LINQ.
