If you are never going to use the Constructor that has no parameters, why define it ?

There could be some reasons: when you want to create a Windows Forms/WPF control. When you add it in the designer or through XAML code, the compiler expects an empty constructor.

Try this:

C#

public A()
    : this(0, 0)
{
}
public A(int a, int b)
{
    // your code here
}

Change 0 into the integers you need.

That's a very interesting answer: upvoted. I didn't know you could actually force a Constructor without parameters to first call a Constructor with parameters before executing its "own" code !
