Invoke a constructor through this
<![CDATA[
The general form is shown here:
constructor-name(parameter-list1) : this(parameter-list2) {
// ... body of constructor, which may be empty
}
using System;
class XYCoord {
public int x, y;
public XYCoord() : this(0, 0) {
Console.WriteLine("Inside XYCoord()");
}
public XYCoord(XYCoord obj) : this(obj.x, obj.y) {
Console.WriteLine("Inside XYCoord(obj)");
}
public XYCoord(int i, int j) {
Console.WriteLine("Inside XYCoord(int, int)");
x = i;
y = j;
}
}
class MainClass {
public static void Main() {
XYCoord t1 = new XYCoord();
XYCoord t2 = new XYCoord(8, 9);
XYCoord t3 = new XYCoord(t2);
Console.WriteLine("t1.x, t1.y: " + t1.x + ", " + t1.y);
Console.WriteLine("t2.x, t2.y: " + t2.x + ", " + t2.y);
Console.WriteLine("t3.x, t3.y: " + t3.x + ", " + t3.y);
}
}
