c# - 解析类变量？

Question

我对 C# 语言还很陌生，因为我几周前才开始使用它，我遇到了一个关于类的简单问题。我坐了整整 30 分钟寻找答案，但就是想不通怎么办要解决这个问题。到目前为止，这是我的代码:

class Program
{
    static void Main(string[] args)
    {
        Plyta p1;
        Plyta p2;
        p1 = new Plyta(p1.ImtiIlgi(), p1.ImtiAuksti());


        p1.ImtiIlgi();
        Console.Write("\niveskite plytos ilgi - ");
        p1.PlytosIlgis = int.Parse(Console.ReadLine());

        p1.ImtiAuksti();
        Console.Write("\niveskite plytos auksti - ");
        p1.PlytosAukstis = int.Parse(Console.ReadLine());

和类文件:

class Plyta
{
    private int ilgis,
                aukstis;

    public Plyta(int PlytosIlgis, int PlytosAukstis)
    {
        ilgis = PlytosIlgis;
        aukstis = PlytosAukstis;
    }


    public int ImtiIlgi() 
    {
        return ilgis;
    }

    public int ImtiAuksti()
    {
        return aukstis;
    }
}

当我运行它时，它给出了以下错误:

'praktika.Plyta' does not contain a definition for 'PlytosIlgis' and no extension method 'PlytosIlgis' accepting a first argument of type 'praktika.Plyta' could be found (are you missing a using directive or an assembly reference?)

我假设我写了错误的变量来解析，但无论我想到什么都行不通，对初学者有什么帮助吗？ :)

Answer 1

我认为您对方法的作用以及初始化对象的时间感到困惑。我怀疑你真的想做这样的事情:

class Program
{
    static void Main(string[] args)
    {
        // Ask the user for the relevant data
        Console.WriteLine("iveskite plytos ilgi - ");
        int ilgis = int.Parse(Console.ReadLine());

        Console.WriteLine("iveskite plytos auksti - ");
        int aukstis = int.Parse(Console.ReadLine());

        // Now we're in a position to create the object
        Plyta p1 = new Plyta(ilgis, aukstis);

        // And we can read the value back from the property
        Console.WriteLine(p1.Ilgis);
    }
}

class Plyta
{
    // These are public, read-only automatically-implemented properties
    public int Ilgis { get; }
    public int Aukstis { get; }

    public Plyta(int ilgis, int aukstis)
    {
        // Set the properties...
        Ilgis = PlytosIlgis;
        Aukstis = PlytosAukstis;
    }
}

(这使用 C# 6 的只读自动实现属性。如果您不使用 C# 5，请告诉我。)
