How to pass each value of array to method using linq

Let say I have an array:

string[] s = GetAr开发者_Python百科ray();

and method:

public bool CheckIfInArray() { .. }

I want to pass each value of that array in to the method and get a bool result as soon as there are any first matching (after first matching there no reason to loop to the last element of array ).

Kind of like this:

s.ContainsAtLeasFirstMatching(x => CheckIfInArray(x))

I don't want to use loops. Is it possible to achieve this with LINQ?

I presume the signature of the method is actually:

public bool CheckIfInArray(string str) { .. }

In that case, you can write:

string[] s = GetArray();
bool atLeastOneMatch = s.Any(CheckIfInArray);

If you are interested in using the first matched element, you can also use FirstOrDefault:

// firstMatch will be null if there is no match
string firstMatch = s.FirstOrDefault(CheckIfInArray);

---

You can do this with the Any() method.

s.Any(x => CheckIfInArray(x))

You may want to take a look at the Enumerable Methods MSDN page to see wich methods are available to you and what they are used for.
