如何链接这些构造函数(C#)？

Question

我只是将构造函数链接起来的概念,但我无法弄清楚如何将这两个特定的构造函数链接在一起,所以如果有人可以帮助我,我将不胜感激.

谢谢!

构造函数

// default constructor
// purpose: initialize data members to zero
// Parameters: none
// returns: none
public Line()
{
    startPoint.xCoord = 0;
    startPoint.yCoord = 0;
    endPoint.xCoord = 0;
    endPoint.yCoord = 0;
}


// parameterized constructor
// purpose: initialize data members to p1 and p2
// Parameters: Point objects p1 and p2
// returns: none
public Line(Point p1, Point p2)
{
    startPoint = p1;
    endPoint = p2;
}

public Line() : this(new Point(), new Point())
{
}
