Having Trouble on Code Challenge: Virtual Methods

I am having trouble on the code challenge 'Virtual Methods'. When I run my code, I get the errors: RepeatDetector.cs(9,26): error CS0029: Cannot implicitly convert type System.Random' toint' RepeatDetector.cs(9,47): error CS0019: Operator -' cannot be applied to operands of typeSystem.Random' and `int'

I know why I am getting these errors, but I can't figure out any other way to solve this code challenge.

Thanks in advance!

Hi Chiroi. Without seeing your code it's hard to troubleshoot. Not sure what you are using system.random for.

I assume you are on part 3 of the challenge. I simply used a foreach loop to loop through the array. If int = previous int then I returned true. If not I set previous int equal to the int. Finally if the loop ends I return false since it didn't find anything.

Feel free to post your code if you are still having issues and I can help more. Good luck. Keep at it!
