Question

我正在学习C＃中的OOP，我在编码过程中遇到了问题。我想用构造函数创建一个类，它将通过public class Klasa { int zarobki; string nazwisko; string stanowisko; public Klasa(string a, string b, string c) { a = (Console.ReadLine()); b = (Console.ReadLine()); c = (Console.ReadLine()); zarobki = int.Parse(a); nazwisko = b; stanowisko = c; } }读取属性。不幸的是，我得到了一个我无法理解的奇怪错误。

这是我的班级：

编译后，我收到以下错误：

“严重性代码说明项目文件行抑制状态错误CS7036没有给出对应的参数需要'Klasa.Klasa的正式参数'a'（字符串，字符串， '）ConsoleApplication17 c：\ users \ dell \ documents \ visual studio 2015 \ Projects \ ConsoleApplication17 \ ConsoleApplication17 \ Program.cs 13有效 ”

Answer 1

你应该从其他地方调用构造函数。在控制台应用程序中像这样：

void Main()
{
    var a = (Console.ReadLine());
    var b = (Console.ReadLine());
    var c = (Console.ReadLine());
    Klasa k = new Klasa(a,b,c);
}

然后你的课应该是这样的：

public class Klasa
{
    int zarobki;
    string nazwisko;
    string stanowisko;
    public Klasa(string a, string b, string c)
    {
        zarobki = int.Parse(a);
        nazwisko = b;
        stanowisko = c;
    }
}

这解决了你的问题，但你在结构上被误导了。我认为你应该在开始阅读代码之前先阅读一本书或一篇文章。
