C# - Calling one constructor from another

In order to call one constructor from another constructor in C# programming language you can use below syntax:

class Plane

{

 Plane (){}

 Plane (int a) : this() {}

 Plane (int a, int b) : this(int a) {}

}

In above example constructor Plane (int a) invokes parameterless constructor Plane(). Constructor Plane(int a, int b) invoke two above constructors nested.
