I have a thread adding items to a BlockingCollection
.
On another thread I am using
foreach (var item in myCollection.GetConsumingEnumerable())
BlockingCollection<T> yourBlockingCollection = new BlockingCollection<T>();
I assumed you mean clear your blocking collection. Jon's answer is more appropriate to your actual question I think.
For just clearing the collection you can do:
myBlockingCollection.TakeWhile<*MyObject*>(qItem => qItem != null);
or just
myBlockingCollection.TakeWhile<*MyObject*>(qItem => true);
Just take out all remaining items:
while (collection.TryTake(out _)){}
This worked for me
while (bCollection.Count > 0)
{
var obj = bCollection.Take();
obj.Dispose();
}
Take()
removes from the collection and you can call any clean up on your object and the loop condition does not invoke any blocking calls.
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.
Possibly use the overload of GetConsumingEnumerable
that takes a CancellationToken
; then, if anything goes wrong from the producing side, it can cancel the consumer.
