#298 – A struct Can Have Several Constructors
April 11, 2011 3 Comments
You can define more than one constructor for a struct, as long as the method signature for each constructor is different.
public struct Point3D { public double x; public double y; public double z; public Point3D(double xi, double yi, double zi) { x = xi; y = yi; z = zi; } public Point3D(int n) { x = n; y = n; z = n; } }
Now you can instantiate a variable of this type in several different ways.
Point3D pt1 = new Point3D(); // Default parameterless constructor Point3D pt2 = new Point3D(10.0, 20.0, 30.0); Point3D pt3 = new Point3D(5);
