c# - How do I retrieve a list or number of jobs from a printer queue?

Question

I'm looking for a way to get a list or number of jobs from a particular printer. In the best case I would want to have a "Job object" that represents one print job and its name in the print queue.

This is required because I need to monitor the state of a printer so I can refill the print queue with a new batch of documents without overflowing the print spooler

Thanks in advance!

Edit: added code fragment of solution

private int GetNumberOfPrintJobs()
{
    LocalPrintServer server = new LocalPrintServer();
    PrintQueueCollection queueCollection = server.GetPrintQueues();
    PrintQueue printQueue = null;

    foreach (PrintQueue pq in queueCollection)
    {
        if (pq.FullName == PrinterName)
            printQueue = pq;
    }

    int numberOfJobs = 0;
    if (printQueue != null)
        numberOfJobs = printQueue.NumberOfJobs;

    return numberOfJobs;
}

You can use the .NET 3.0 PrintQueue class in the System.Printing namespace. Its NumberOfJobs property tells you how many jobs are queued, GetPrintJobInfoCollection() returns details on all the jobs. Beware that it doesn't have any events that tells you that the job collection changed, you need to poll with a timer. Once a second or so ought to be fine.
