修改GetOutput()方法，使其返回c#的详细信息

这是一种最后的手段。在我的一个实验室里，我遇到了一个问题，我无法解决它，甚至无法理解它，因为我真的不擅长c# !不管怎样，最初的问题是:在类DogChorus中，更改GetOutput()方法，使其返回所有创建的狗的详细信息，包括所有狗的腿的数量。有一个提示是"你需要调用通过类名创建的静态NoOfLegs属性"。任何帮助/提示任何人可以给我将非常感激!这两个类的代码如下:

namespace HelloDogs

        public static int NoOfLegs
        {
            get { return Dog.noOfLegs; }
            set { Dog.noOfLegs = value; }
        }
        public int DogHeight
        {
        get { return dogHeight; }
        set { dogHeight = value; }
        }
        private string dogColour;
