Question

i want to configure my Thread to be background thread, why this property missing in my Thread ?

    ThreadStart starter = delegate { openAdapterForStatistics(_device); };
    new Thread(starter).Start();

public void openAdapterForStatistics(PacketDevice selectedOutputDevice)
{
    using (PacketCommunicator statCommunicator = selectedOutputDevice.Open(100, PacketDeviceOpenAttributes.Promiscuous, 1000)) //open the output adapter
    {
        statCommunicator.Mode = PacketCommunicatorMode.Statistics; //put the interface in statstics mode                
        statCommunicator.ReceiveStatistics(0, statisticsHandler);

    }
}

i have try:

Thread thread = new Thread(openAdapterForStatistics(_device));

but i have got 2 compilation errors:

1. The best overloaded method match for ‘System.Threading.Thread.Thread(System.Threading.ThreadStart)’ has some invalid arguments
2. Argument 1: cannot convert from ‘void’ to ‘System.Threading.ThreadStart’

and i don’t know why

Answer 1

About the background thing, I don’t see how you expect to set it since you’re not keeping a reference to the thread. Should look like this:

ThreadStart starter = delegate { openAdapterForStatistics(_device); };
Thread t = new Thread(starter);
t.IsBackground = true;
t.Start();

This

Thread thread = new Thread(openAdapterForStatistics(_device));

won’t work because you’re supposed to pass in a method that takes object as parameter, while you’re actually passing the result of a method call. So you could do this:

public void openAdapterForStatistics(object param)
{
    PacketDevice selectedOutputDevice = (PacketDevice)param;
    using (PacketCommunicator statCommunicator = selectedOutputDevice.Open(100, PacketDeviceOpenAttributes.Promiscuous, 1000)) //open the output adapter
    {
        statCommunicator.Mode = PacketCommunicatorMode.Statistics; //put the interface in statstics mode                
        statCommunicator.ReceiveStatistics(0, statisticsHandler);

    }
}

and:

Thread t = new Thread(openAdapterForStatistics);
t.IsBackground = true;
t.Start(_device);
