c# - 使用构造函数链来完成此构造的正确方法？

Question

我的第一个 OOP 类(class)有一个作业，我理解所有作业，包括以下语句:

You should create a class called ComplexNumber. This class will contain the real and imaginary parts of the complex number in private data members defined as doubles. Your class should contain a constructor that allows the data members of the imaginary number to be specified as parameters of the constructor. A default (non-parameterized) constructor should initialize the data members to 0.0.

我当然知道如何在不将它们链接在一起的情况下创建这些构造函数，并且赋值不需要将它们链接在一起，但我想这样做，因为我喜欢这样做。

如果不将它们链接在一起，我的构造函数如下所示:

class ComplexNumber
{
    private double realPart;
    private double complexPart;

    public ComplexNumber()
    {
         realPart = 0.0;
         complexPart = 0.0
    }

    public ComplexNumber(double r, double c)
    {
         realPart = r;
         complexPart = c;
    }
    // the rest of my class code...
}

Answer 1

这是您要找的吗？

public ComplexNumber()
    : this(0.0, 0.0)
{
}

public ComplexNumber(double r, double c)
{
     realPart = r;
     complexPart = c;
}
