If you allow someone to open a text file and lets say you don't allow to copy the 'file', does that do any good? What were you trying to achieve here - not allowing anyone to copy content, just read?

Why I ask so, if you allow opening a text file then you are allowing to copy the 'content' and thus all your effort to not allow copying the 'file' goes into vain.

I doubt, there is some flaw in your logic or requirement. Pick correct control/flow.

making text file read only means allowing user to read but user cannot copy the whole file

Readonly file is to read the file and dont allow to copy file is to restrict the user from copying the whole file, yhe logic/ flow is correct, also posted answer is not an answer

Agree on this one as well.
I dont think Rajesh can read between the lines and see the holes in the questions logic.

I don't think you can make a copy protected file.
If you don't want people to see what's inside your file you should encrypt it.

Assuming you're creating a text file. See the following MSDN page for an example on changing file attributes:"File.SetAttributes Method"[^].

As far as I know, you cannot do that (you may encrypt the file, if you want to hide it's content).
