从VB.NET到C＃的属性和方法重写转换

Question

我正在研究VB.NET和C＃，我在VB中有以下代码，这些代码是在C＃中转换的。 该代码具有一个Form，一个基类Vehicle和一个派生类Car。 在VB中，基类Vehicle为4个属性，只声明了一行，而没有set＆get，而在C＃中，我首先必须声明变量，然后再声明4个具有set＆get方法的属性（以及很多行）。 是正确的方法还是VB中有一种简单的方法？

VB.NET

Public Class Form1
    Private Sub Button1_Click(sender As Object, e As EventArgs) Handles Button1.Click
        Dim myCar As New Car()
        myCar.Make = "Ferrari"
        myCar.Model = "Testa rossa"
        myCar.Year = 1999
        myCar.Color = "Red"

        PrintVehicleDetails(myCar)
    End Sub

    Public Sub PrintVehicleDetails(ByVal _vehicle As Vehicle)
        Console.WriteLine("Here is the car's details: {0}", _vehicle.FormatMe())
    End Sub
End Class


Public MustInherit Class Vehicle
    Public Property Make As String

    Public Property Model As String

    Public Property Year As Integer

    Public Property Color As String

    Public MustOverride Function FormatMe() As String

End Class


Public Class Car
    Inherits Vehicle
    Public Overrides Function FormatMe() As String
        Return String.Format("{0} - {1} - {2} - {3}",
                              Me.Make, Me.Model, Me.Year, Me.Color)
    End Function
End Class

C＃

public partial class Form1 : Form
{
    public Form1()
    {
        InitializeComponent();
    }

    private void button1_Click(object sender, EventArgs e)
    {
        Car myCar = new Car();
        myCar.make = "Ferrari";
        myCar.model = "Testa rossa";
        myCar.year = 1999;
        myCar.color = "Red";

        PrintVehicleDetails(myCar);
    }

    private void PrintVehicleDetails(Vehicle _vehicle)
    {
        Console.WriteLine("Here is the car's details: {0}", _vehicle.FormatMe());
    }
}    

abstract class Vehicle
{
    string Make = "";
    string Model = "";
    int Year = 0;
    string Color ="";

    public string make
    {
        get
        { return Make; }

        set
        { Make = value; }
    }

    public string model
    {
        get
        { return Model; }

        set
        { Model = value; }
    }

    public int year
    {
        get
        { return Year; }

        set
        { Year = value; }
    }

    public string color
    {
        get
        { return Color; }

        set
        { Color = value; }
    }

    abstract public string FormatMe();
}

class Car : Vehicle
{
    public override string FormatMe()
    {
        return String.Format("{0} - {1} - {2} - {3}", 
                             this.make, this.model, this.year, this.color);
    }
}

您也可以像下面这样直接定义属性

abstract class Vehicle
{
    public string Make { get; set; } = string.Empty;

    public string Model{ get; set; } = string.Empty;

    public int Year{ get; set; } = 0;

    public string Color { get; set; } ;
}
