Filling a template with information.

Question

I have been given a project from my manager which has got me kind of confused. I am relatively new to C# so bear with me.

We have a template provided to us that was used in a program that is now out of use, it has a nice html document with all of the values to be marked like %name% and %cost%. Now I would guess I could just open the file and search for those variables, the previous program however dealt with multiple variables. There are several %name% in there and %lesson% has several entries.

What I would like to know is - Is there an easy way to go manage the replacement of the holders?
