Question

In my asp.net project, I have two strings (actually, they are stored in a Session object, then i do a .ToString() )

This project is part of my free Japanese language exercises on my website (Italian only for now, so i won’t link/spam)

For now i do an if (original == inputted.ToLower()) , but I would like to compare the strings and highlight the differences on the screen

like this:

original: hiroyashi
wrote by user: hiroyoshi

i was thinking to compare the two strings and save the differences in another variable, with HTML tags, and then show it on a Literal control… but… if the differences are many, or the input is shorter… how to do that?

It looks there is the needing of an huge amount of coding… or not?

Answer 1

I seem to remember someone asking this not too long ago, and essentially they were pointed at difference engines.

A quick search on codeplex brings up:

May be worth a hunt through some of those that come up – you may be able to plug something into your existing code?
