在数组匹配查询中查找元素数

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?

Answer 1

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);
