如何用c#定义盒子box类？

题主要的代码如下，有帮助麻烦点个采纳【本回答右上角】，谢谢~~有其他问题可以继续交流~

using System;
namespace ConsoleApp1
{
    class Box
    {
        public double Length { get; set; }
        public double Width { get; set; }
        public double Height { get; set; }
        public void SetBox(double Length,double Width, double Height)
        {
            this.Length = Length;
            this.Width = Width;
            this.Height = Height;
        }
        public double GetVolume()
        {
            return Length * Width * Height;
        }
        public double GetArea() {

            return (Length * Width + Length * Height + Width * Height) * 2;
        }
    }
    class Program
    {
        static void Main(string[] args)
        {

            var box = new Box { Length = 3, Width = 4, Height = 5 };
            Console.WriteLine("体积：" + box.GetVolume());
            Console.WriteLine("面积：" + box.GetArea());
            box.SetBox(5, 5, 5);
            Console.WriteLine("体积：" + box.GetVolume());
            Console.WriteLine("面积：" + box.GetArea());

            Console.ReadKey();
        }
    }
}
