如何从另一个 class 访问 stringbuilder 类型的变量？

Question

我是 c# 的新手，仍在学习，我不确定将其放入结构中是否正确，我想在另一个 class 中访问汽车设备以打印其信息。我该怎么做呢？

我试过将它从结构更改为 class，我还确保在另一个 class

中实例化该结构

```  struct car
    {
        public void StringBuilder()
        {
            StringBuilder automotivedevice = new StringBuilder();
            Console.WriteLine("enter brand of the car");
            StringBuilder CarBrand = automotivedevice.AppendLine(Console.ReadLine());

            Console.WriteLine("enter mileage of the car");
            StringBuilder CarMileage = automotivedevice.AppendLine(Console.ReadLine());

            Console.WriteLine("enter number of cylinders in the car");
            StringBuilder NumberOfCylinders = automotivedevice.AppendLine(Console.ReadLine());
        }
    }```

Answer 1

class Program
{
    static void Main(string[] args)
    {

        // collect all user input
        Console.WriteLine("enter brand of car...");
        string brandInput = Console.ReadLine();

        Console.WriteLine("enter mileage of car...");
        string mileageInput = Console.ReadLine();

        Console.WriteLine("enter number of cylinders in the car...");
        string cylinderCountInput = Console.ReadLine();

        // create instance of car and assign user input to car properties
        Car myCar = new Car();
        myCar.Brand = brandInput;
        myCar.Mileage = mileageInput;
        myCar.NumberOfCylinders = cylinderCountInput;

        // output values in the car object to the console window
        Console.WriteLine("Brand: " + myCar.Brand);
        Console.WriteLine("Mileage: " + myCar.Mileage);
        Console.WriteLine("Cylinder Count: " + myCar.NumberOfCylinders);

        Console.WriteLine("press <ENTER> to close the console window");
        Console.ReadLine();
    }


}


public class Car
{
    public string Brand { get; set; }
    public string Mileage { get; set; }
    public string NumberOfCylinders { get; set; }
}
