How to edit hardcoded string in compiled dll?

Question

I have one compiled dll that I need to modify a bit. It was written by me six months ago, but I lost the source code. It has one hard-coded string (this is the file name)

I need to change it from TestPage.htmlto TestPage1.html(it's not much more)

How to do it? The line is anonymous, the corresponding code fragment:

... + folder + "TestPage.html"

There is no variable to which it is assigned.

Thanks in advance.

EDIT: I don't want to recompile C # code after retrieving it with Reflector tools!
