How to call system.threading.timer on same thread?

Everytime I switch something on my form, I restart my thread by doing (to call whatever was switched):

Retriever.Dispose();
Retriever = new System.Threading.Timer(CallPictureBoxRetriever, null, 0, 300000);

The problem is that this is yet creating another thread and closing the previous!

I am asking how can I call CallPictureBoxRetriever(Object state) on the same thread created so therefore I do not have to always dispose/recreate a thread; rather have 1 thread.

Personally, I would create a thread that waits on an autoresetevent with a timeout of 30 seconds. Then have your code set the autoresetevent when you want it to run immediately.

Just reset the timer:

Retriever.Change(0, 300000); // reset to 300 seconds

First argument is dueTime:

Specify zero (0) to restart the timer immediately.

Second is period:

The time interval between invocations of the callback method specified when the Timer was constructed, in milliseconds. Specify Timeout.Infinite to disable periodic signaling.
