How to empty a BlockingCollection

I'm using this extension method:

public static void Clear<T>(this BlockingCollection<T> blockingCollection)
{
    if (blockingCollection == null)
    {
        throw new ArgumentNullException("blockingCollection");
    }

    while (blockingCollection.Count > 0)
    {
        T item;
        blockingCollection.TryTake(out item);
    }
}

I'm wondering if there's a better, less hacky, solution.

Just take out all remaining items:

while (collection.TryTake(out _)){}
