Compare 2 codes (2 possible solutions ) {C#}

parallel

i'm trying to make a windows form program to teach the c# language...

so i need to give an exercise ( like add 2 integers and show their sum )

the user must put their code in a text box and the compiler will process it



but now it comes that part ,, that the exercise might have more than one possible solution that gives the same result

and i want to check if the user's code is right ?

What I have tried:

i have the idea to put a verified solution in XML file and then run the 2 programs in parallel on the same examples and check the results

but how can i match the parameters to fit into the 2 programs ( maybe the user use more or less parameters or something ... ) !

any ideas please ? or there is another methods to compare 2 codes ?!



(sorry i didn't put any piece of code here ,, i don't think that this will make a difference .. i want to know how to compare 2 codes in general)
