Trailing File Reader and Processor

Looking for a C# program that will read a file that changes many times a second. The program will need to detect changes and only process the lines that are new. Each line will be passed through a single class to determine the type of line. Each line contains a date stamp, a category block such as [Skill] or [Team].. those category blocks will determine which subsequent method it will go to for additional processing. For example: [Skill] You have earned skill Perception. I would need to process this line as perception and increment a counter on the winform by 1. In the winform, there needs to be a list box that will keep track of each mob loot. As this would be multiple lines, it would need to read a group of [Team] that are within 1 or 2 seconds apart (make this adjustable in a config file or in the winform screen) as one mob loot. Example: There would be lines such as: [12:03:06] [Team] Person looted an item Shrapnel (63421). [12:03:07] [Team] Person looted an item Animal Muscle Oil (31). [12:03:08] [Team] Person looted an item Weapon Cells (438). It would track this in a few ways: 1) In the listbox, it would say Kill ID#, Timestamp when Mob was Killed, # of Items, TT value of those Items -------------------------------------------------------------------------------------- 1, [12:03], 3, (See below) Kill ID would be a counter as each item that is looted should be tied to the kill id. When the program first opens, it will need to pull a list of all items from a database (you can stub this for now) and what the value is for each item. For example, 1 muscle oil is 0.03. So the example above would be 31 x 0.03. Shrapnel and Weapon cells is 0.01. So, the TT value in the listbox would read: 639.52. So as each line is processed, it will query this list or key,value pair to determine what the value is per 1 unit. Second, for the duration of the hunt/log, all items and quantity will be summed up in a separate list box. It would be a tally of everything looted. It would have 3 columns also: Item, Quantity, Total TT Value Lastly, some items will not have any quantity to them. They will need to be adjusted manually. To do this, we would need another listbox with these items and when they are clicked on, will bring up a textbox to enter the TT value of it. When saved, it will remove from that pending adjustment listbox and update the other 2 list boxes accordingly. Finally, the listbox contents and the items looted in each kill ID should be in a object collection so that we can expand this program in the future OR later on, I can have all that data input into a database for additional analysis. Please let me know if you have questions.
