如何使用队列发送数据？

Question

If I was to, from various sources, put data in a queue, and whenever it has anything to send, it sends it and then waits for a time. So, for example, the queue is empty, I send in 2 things to send, it sends the first thing instantly and then waits for a bit before sending the next. How would I do this?

Answer 1

Sounds like you should have a producer/consumer queue, with a single consumer which delays after consuming. (The consumer would be on a different thread to the producers, of course.)

From .NET 4 onwards, BlockingCollection<T> is the fundamental building block of producer/consumer queues. You should also look at TPL DataFlow though - it may have a simple way of doing this out of the box. (DataFlow is a library specifically aimed at producer/consumer scenarios.)
