我想为每辆车设定价格，但它显示出一个错误
//vehicle program
using System;
namespace LAB_4
{
class Vehicle
{
private string Brand;
private string Model;
private int Price;
public string Getbrand()
{return Brand;}
public void Setbrand(string a)
{ Brand = a; }
public string Getmodel()
{ return Model; }
public void Setmodel(string a)
{ Model = a; }
public int Getprice()
{ return Price; }
public void Setprice(int a)
{ Price = a; }
}
class program
{
static void Main(string[] args)
{
Vehicle Toyota = new Vehicle();
Toyota.Setbrand("TOYOTA");
Toyota.Setmodel("TOYOTA SIGMA 4");
Toyota.Setprice = 9149000;
Vehicle Suzuki = new Vehicle();
Suzuki.Setbrand("HONDA");
Suzuki.Setmodel("HONDA BR-V");
Suzuki.Setprice = 34800000;
Vehicle Faw = new Vehicle();
Faw.Setbrand("AUDI");
Faw.Setmodel("AUDI Q5");
Faw.Setprice = 27000000;
Console.WriteLine("================TOYOTA=============");
Console.WriteLine("Toyota Sigma 4 Details are Given below");
Console.WriteLine("Brand: {0}\nModel: {1}\nPrice: {2}", Toyota.Getbrand(),Toyota.Getmodel(), Toyota.Getprice());
Console.WriteLine("================HONDA=============");
Console.WriteLine("Honda BR-V Details are Given below");
Console.WriteLine("Brand: {0}\nModel: {1}\nPrice: {2}", Suzuki.Getbrand(), Suzuki.Getmodel(),Suzuki.Getprice());
Console.WriteLine("================AUDI=============");
Console.WriteLine("AUDI Q5 Details are Given below");
Console.WriteLine("Brand: {0}\nModel: {1}\nPrice: {2}", Faw.Getbrand(), Faw.Getmodel(), Faw.Getprice());
Console.ReadKey();
}
}
}
您可以使用C#中包含的属性，有一个属性叫做自动实现的属性，它使您的程序比使用方法更简洁
基本上在您的程序上，您可以这样做（我没有使用自动实现的属性）
private string brand = "";
private string model = "";
private int price;
public string Brand{ get{ return brand; } set{ brand = value; } }
public string Model{ get{ return model; } set{ model = value; } }
public int Price{ get{ return price; } set{ price = value; } }
并且基本上可以使用对象初始化来初始化类上的所有属性
Vehicle Toyota = new Vehicle{ Brand = "Toyota", Model = "Toyota Sigma", Price = 1000};
然后打印所有需要打印的数据。
