Random.Next not working?

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.

By any chance are you using Unity3d, if you are you need to mark your question as such in the tags, Unity3d has a static `Random` class that you can call `Random.Next(rooms.Count)` on but normal .NET does not. — Scott Chamberlain, Apr 09 '17 at 15:57

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]);
