Please someone help me, I've been staring at this for hours cause I am new to this and coding in general.

Rules of the Game:

Two players each roll a pair of dice until one player wins. Each time they roll is called a 'battle.' First to win 5 battles wins the game. The winner of a battle is determined by these rules:

1. Doubles always wins over non-doubles. E.g., 1-1 wins over 6-5.

2. Higher doubles wins over lower doubles. E.g., 4-4 wins over 3-3.

3. If both players roll non-doubles, then the higher total roll wins. E.g., 5-4 (9) wins over 5-3 (8).

4. If the players roll the same, no one wins that battle.

here's my dice class which I'm 98% sure if perfect

Code:
using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;

namespace dice1
{
    class PairOfDice
    {
        private int die1, die2;
        private Random random1;

        public PairOfDice()
        {
            random1 = new Random();
        }

        public int Die1
        {
            get
            { return die1; }
            set
            { die1 = value; }
        }

        public int Die2
        {
            get
            { return die2; }
            set
            { die2 = value; }
        }

        public int SumOfFaces()
        {
            return die1 + die2;
        }

        public void Roll()
        {
            die1 = random1.Next(1, 7);
            die2 = random1.Next(1, 7);
        }

        public bool isDoubles()
        {
            return(die1==die2);
    }
}
and here's where i am having so many troubles in my form 1

Code:
using System;
using System.Collections.Generic;
using System.ComponentModel;
using System.Data;
using System.Drawing;
using System.Linq;
using System.Text;
using System.Windows.Forms;
using dice1;

namespace DiceBattleKevin
{
    public partial class Form1 : Form
    {
        private PairOfDice pair1 = new PairOfDice();
        private PairOfDice pair2 = new PairOfDice();
        bool P1_doubles;
        bool P2_doubles;
        int P1_sum; 
        int P2_sum;
        
        public Form1()
        {
            InitializeComponent();
            System.Threading.Thread.Sleep(400);  
            P1_doubles = pair1.isDoubles();
            P2_doubles = pair2.isDoubles();
            P1_sum = pair1.SumOfFaces();
            P2_sum = pair2.SumOfFaces();
        }

        private void RollButton_Click(object sender, EventArgs e)
        {
            //Roll the dice

            

            //When button is clicked, number shows up in for die1 and die2


            //Show the value of dice
            //disable the roll button

            if(P1_doubles)
            { if(P2_doubles)
                //both doubles


            }
            else if (P2_doubles)
            { //p2 wins

            }
            else
            { //neither are double
                //check sum

            }

        }

        private bool BattleOver()
        {

        }

        private void DeclareWinner()
        {
            //Declare winner
        }
        
        private void ShowScores()
        {
            //Set the label of P1's score to his score
            //Set the label of p2's score to his score
        }

        private void NewGameButton_Click(object sender, EventArgs e)
        {

        }

 

  

    }
}
Where i am stuck right now is at RollButton_Click. I just don't know how to get the dice to roll (from the dice class) and how to get that roll to show up. Any help would be great. Thank you!
