I coulda sworn it was possible to overwrite specific lines in a text file
without disturbing the rest, or was that in C++?

Will a TextWriter object do this?

Is the new line of text *exactly* the same size (in bytes, after
encoding) as the old line? If so, it's possible. It not, it's not. You
can't just arbitrarily insert and delete data from the middle of
files.

You could script edlin to change a line. That brings back memories! Under
the hood I'm sure it's not different then the following:

string [] lines = File.ReadAllLines("somefile.txt");
lines [someline] = "a new line";
File.WriteAllLines ("somefile.txt", lines);
