i had to repost. any help with my code?

When you get your book, you'll see that all property setters have access to an implicit variable called 'value' which contains the value to which the property is being set.

Try this code for the weight property:

so i made some changes in my code.....


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

namespace the_helped
{
    class Animal
    {
        private string name;
        private string race;
        private double _weight;
        private double _age;

        public double age
        {
            get
            {
                return _age;
            }
            set
            {
                if (_age > 0 && _age <= 60)
                {
                    _age = value;
                }
                else
                {
                    do
                    {
                        Console.WriteLine("Invalid Age!\nDog's age: " + _age);
                        Console.Write("Please enter dog's age: ");

                    } while (_age < 0 && age > 25);
                }
            }
        }
        public double weight
        {

            get
            {
                return _weight;
            }
            set
            {

                if (_weight > 0 && _weight <= 60)
                {
                    _weight = value;
                }

                else
                {
                    do//for some reason my do while is not executing, i am a beginner but
                        //this seems to be correctly written to me. well obviously
                        //somethings wrong if it does not do what i want it to do
                    {

                        Console.WriteLine("Invalid Weight!\nDog's weight: " + _weight);
                        Console.Write("Please enter dog's weight: ");
//here i also tried putting '_weight = double.parse.(console.ReadLine());' but
//nothing changed im trying to get information on set and get over the internet
//because i do not have the book yet (i know i need to purchase it but they are too
//expensive for me now) but specific information is a little tough to come by.

                    } while (_weight < 0 && _weight >= 60);

                }



            }
        }

        public Animal()
        {
            Console.Write("\nThese are the constructor details : ");

        }
        public void getdetails()
        {
            _age = 1;
            _weight = 1;
            Console.WriteLine("\n\nName: No Name");
            Console.WriteLine("Race: No Race");
            Console.WriteLine("Weight: " + _weight);
            Console.WriteLine("Age: " + _age);
            Console.WriteLine();
        }
        public void info()
        {
            Console.WriteLine("\nDog's name: " + name);
            Console.WriteLine("Dog's race: " + race);
            Console.WriteLine("Dog's age: " + age);
            Console.WriteLine("Dog's weight: " + weight);
            Console.ReadLine();
        }


        public static void Main(String[] args)
        {
            Animal dog = new Animal();

            dog.getdetails();

            Console.Write("Please enter your dog's name: ");
            dog.name = Console.ReadLine();
            Console.Write("Please enter your dog's race: ");
            dog.race = Console.ReadLine();
            Console.Write("Please enter your dog's age: ");
            dog.age = double.Parse(Console.ReadLine());
            Console.Write("Please enter your dog's weight: ");
            dog.weight = double.Parse(Console.ReadLine());

           
            dog.info();
        
        }
    }
}

It's not working properly because you're setting the age and weight fields directly rather than via the associated properties _age and _weight.

If you make the highlighted changes in the Main() method then all should be well:
