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?

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))
