You can use named Mutexes for cross process synchronization. Below links should help you understand Mutexes and synchronization techniques:

Wanted: Cross-process synch that doesn't suffer from AbandonedMutexException

If you need a robust solution for this cross program or even remote communication consider using a JMS server like ActiveMQ or Microsoft MSMQ (non-JMS). I personally prefer ActiveMQ.

ActiveMQ has adapters for publish and subscribe for topics and queues. You can use http://activemq.apache.org/nms/ for connecting thru C#.

What you're looking for is named pipes.
