Unfortunately, things start getting very complicated when move from accessing local resources to accessing resources over Internet. It is a completely different approach. I remember providing the Windows Forms solution. You will need to download the .txt file from the Internet first and then parse it. I suggest you write a separate method / function which will do this. There are several ways in which you can do this. You can use HttpClient class or you can even use WebBrowser control also. You definitely cannot access the file as you are trying to do it (at least today, to the best of my knowledge).

First, from whatever i have done so far, the kind of code you are writing looks very ambitious to me. Please let me know if it is a web application (asp.net / mvc) or windows forms application. A lot depends on that. Where are these text files? Are they on your server (where you have access to file system) or over the Internet (where you do not have access to file system)? If the files are over the Internet, then you will need to first download them programatically and then read.
