How to chain these constructors (C#)?
I'm just getting the concept of chaining constructors down, but I can't figure out how to chain these two particular constructors together, so I would appreciate it if somebody could help me out.
Thanks!
Constructors
// 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;
}
// pa开发者_如何学JAVArameterized 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())
{
}
There's really no win in chaining these.
Try the following
public Line() : this(new Point(0,0), new Point(0,0))
{
}
This will work for you
// default constructor
// purpose: initialize data members to zero
// Parameters: none
// returns: none
public Line() : this (new Point(0, 0), new Point(0, 0))
{
}
