Question

The following is creating a number of errors i.e “B” is not recognized (as well as the other 20 letters and “File” is not recognized.

I can’t see the problem here?

string[] correctAnswers = {B,D,A,A,C,A,B,A,C,D,B,C,D,A,D,C,C,B,D,A}; 
string[] studentResults = File.ReadAllLines("studentResults.txt");

Thankyou

You should wrap them in double quotes:

string[] correctAnswers = {"B","D","A","A","C","A","B","A","C","D","B","C","D","A","D","C","C","B","D","A"}; 

Edit :

(Thanks to @goldenparrot) You need to add this namespace :

using System.IO;

to be able to use File.ReadAllLines(). either that or :

string[] studentResults = System.IO.File.ReadAllLines("studentResults.txt");
