Find number of elements in array matching query

Question

I have the following class:

public class Words
{
    public string word;
    public bool correct;
}

and I have an array of Words.

Words[] words;

I wish to count how many elements in my array have the property correct set to true.

What would be the most efficient way to do this?

Most efficient would be keep track of how elements have the property correct set to true, so you don't have to count them. — dtb

I agree with KingCronus. Plus it would require storing an extra variable, which would only make the code more messy. I believe that the LINQ solution is more elegant and definitely answers my question :) — kUr4m4

Using LINQ

words.Where(w=>w.correct);

That should do the trick to filter.

But if you only want to count:

words.Count(w=>w.correct);

I knew it was something like that, I just didn't know the correct syntax/method :) Thank you very much!
