Partial match from string array

Question

I've got a string array that looks like this:

string[] userFile = new string[] { "JohnDoe/23521/1", "JaneDoe/35232/4", ... };

I'm trying the following but this will only return exact matches. I want to be able to return a match if I am searching for "23521".

var stringToCheck = "23521";

if (userFile.Any(s => stringToCheck.Contains(s)))
{
    // ...

Your Contains() call should be the other way round:

if (userFile.Any(s => s.Contains(stringToCheck)))

You want to check whether any string s in your userFile string array contains stringToCheck.

Thanks. Can I now select the whole string and then check if the third item in the string (the number after the second delimiter) is equal to a value.

Can you clarify your question? Not sure what you mean - or do you mean just if(userFile[2] == stringToCheck) ?

if (userFile.Any(s => stringToCheck.Contains(s))) ... if yes now check if the number after the second "/" in "JohnDoe/23521/1" is for example greater than 0 and then put that number into a variable.

You have to iterate over the items that fit the condition - foreach(var matchingItem in userFile.Where(s => stringToCheck.Contains(s))) then you can use matchingItem.Split('/') - look up the methods on msdn

You want to check if the string in the array contains the check string, not the other way around:

userFile.Any(s => s.Contains(stringToCheck))

The following seems like a better choice:

if (userFile.Any(s => s.Contains(stringToCheck)))
