Random.Next not working? [duplicate]

Question

I'm trying to make a random room selector and Random.Next seems to not be working, please help!

List<string> rooms = new List<string>();
rooms.Add(room1);
rooms.Add(room2);   
int index = Random.Next(rooms.Count);
System.Console.WriteLine(rooms[index]);

The systems I am using (I think this may be the problem)

Using System
Using System.Collections.Generic
Using.Collections

Using.Collections is greyed out.

Answer 1

your issue is that you want to call the Next method directly on the Random class, unfortunately, there is no static Next method for the Random class.

int index = Random.Next(rooms.Count);

you'll need to make an instance of the Random generator, in order to invoke the Next method.

Example:

Random rand = new Random();
int index = rand.Next(rooms.Count); 
System.Console.WriteLine(rooms[index]);
