What is the problem with this code? | c#

Question

I basically want to create an int that generates random numbers. I also want to use it in a different class. 
Does anyone know how I can do that?  
My code:
class Random 
{
Random rnd = new Random();
public int num01 = rnd.Next(1, 20);
public int num02 = rnd.Next(1, 10);
}

Hi Liam,
Assuming your lower bound is 1 and upper bound is 20, you could use a static class like so
C#
namespace WhateverYourAppNameSpaceIs
{
           static class Random
           {
                     public int Next() 
                     {
                                 System.Random rnd = new System.Random();
                                 return rnd.Next(1, 20)
                     }
           }
}

The above technique of using a static Random class neatly refactors a random number generator for your application. Now, whenever you wish to generate a random number from anywhere in your client / consuming code all you need to do is write this statement :
C#
int random = Random.Next();

Pay close attention as I don't need to create a random class object every time I need a random number generated; I am calling the Next() method on Random class directly that I have created within the app's namespace.
Hope that helps, and happy coding :)
