Question

I have two strings:

string strone="what is your name?"
string strtwo="what is your name? what is your school name?"

Any of the strings could be greater here. What I need is to extract string from strtwo which is not in strone.

What I have tried is this:

IEnumerable<string> str=strtwo.Except(strone); //(returns only first character ie w)

I tried converting both strone and strtwo to string arrays but looping through each string one by one won’t provide solution as strone may contain other characters in between.

What i require is to extract the entire string sequentially in strtwo that is not in strone.

Answer 1

If your looking for something that compares more than just the First part of the strings and shows the diff on the end then have a look at the Diff Implementation, but basically your looking for This Algorithm

However if you are just looking for the difference on the end of a string look at @dasblinkenlight solution
