Loop queue in C#

     public List<Transfer> Queue
     {
         get { return _queue; }
         set { _queue = value; }
     }
    TransferFromQueue()
    {
         // Do stuff
         // Remove transfered item from Queue
    }

My Queue is a variable to which items will be added and removed all the time.

I'm looking for a way to execute TransferFromQueue() whenever there are items in the list. Though it should never be running more than one istance of TransferFromQueue().

How can I loop this queue one by one when there are items in the Queue?
