Answer 1

If others suggested solution do not work, I suggest you setting a limit of characters to read, and read the text by parts. Once you cache a part of the text, you can manipulate it.

If you need to manipulate it in any direction (I mean, not from left to right in one step), you can always implement a B-Tree and store parts of the text in the nodes :)

Sometimes it is almost impossible to work reading a text by parts sequentially, and here's where a B-Tree helps. I implemented it about one year ago for academic purposes (a mini-database manager), but I think there should be implementations of it in C#. Of course, you will have to implement how to load the nodes of the BTree from the file.
