How could I take 1 more item from Linq's TakeWhile?

Question

(line of code of interest is the last one, the rest is just for a full representation)

Using the following code, I wanted to take VOTERS until I exceeded

Answer 1

In a situation where I wanted to execute a function until and including it hit an end condition I did:

public static IEnumerable TakeUntilIncluding(this IEnumerable list, Func predicate)
{
    foreach(T el in list)
    {
        yield return el;
        if (predicate(el))
            yield break;
    }
}

Worked for me! I think this is an implementation-agnostic solution like Jason's, but simpler.
