I tried using enumerator. It behaved differtly in different scenarios
Scenario 1 :
I had 1 million messages in a queue and a thread to count the
number of messages, it gave me the exact result in 20 secs.
Seconds
Scenario 1 :
I had 1 million messages in the queue and 30 worker threads
which read from the queue and process the message and one thread to
count the number of messages in the queue. The counter thread gave me
some number after all the worker threads completed processing(more than
20 mins).
This is my problem.
I have a reader thred which keeps reading a record by record
from a CSV file(having more than 5 millions of records) and sends to
MSMQ and I have some 30 worker threads which keeps reading records one
by one from MSMQ and process it.
The problem is the reader thread can not keep sending millions
of messages to MSMQ as there is a memory limit. I treid to send as mamy
messages as possible to msmq. But after sending two and a half million
messages, the MSMQ threw an error saying "Insufficient Memory". So I
need to make reader thread sleep for some time once it sends a million
messages and wake up after some time and start sending messages. Once it
wakes up, I need to know the number of messages in the MSMQ so that It
can send messages accordingle tp prevent from crossing the memory limit.
Please let me know if anything could be done to solve this problem.

I'm not sure if this works, and it is inefficient but call
GetEnumerator() on the MessageQueue class then iterate though each
message incrementing a counter, and voila you have the number of
messages. I'm not sure if iterating is going to pull the messages off,
or that it will be quick!
If you just want to check if the queue is empty or not just do a Peek()
with a timeout.
