constructors (not a C# or .NET specific benefit), I was really just
commenting on the elegant syntax for doing that. I do of course realise
that, that is subjective, do you like it ? (the syntax that is)

inehrited constructor is called, in the second the parameterless

has already createed a parameterless constructor for you with a call to
InitializeComponent, if you remove the paramentless one you will break
the designer but if you just add another constructor now you will need
to make the same call to InitializeComponent.
i.e.
public TheForm()
{
InitializeComponent;
}
public TheForm(SomeClass myObject) : this()
{
BindTheObjectToTheForm();
}
See where I am coming from ?

ok, say you have created a dialog box that you want to use to say edit
one of your classes, and what you also want to do is pass you object
that you want to edit in the constructor to bind it to the form i.e.
MyClassDialog dlg = new MyClassDialog(myClassInstance);
When you have created your dialog the .NET designer has created a
parameterless constructor for you with a call to InitializeComponent
i.e.
public MyClassDialog()
{
InitializeComponent();
}
now, we can not remove this one and place the Init call into our
constructor because this would break the desiger, our options are then
to either duplicate the call to the initialization routine or to chain
it i.e.
public MyClassDialog(MyClass myClassInstance)
{
InitializeComponent();
BindMyClassToTheDialog();
}
or
Public MyClassDialog(MyClass myClassInstance) : this()
{
BindMyClassToTheDialog();
}
I personally prefer the chaining approach, appeals to my sense of reuse.
Regards Tim.

the this() call in the body of the constructor with the parameter.
public MyClassDialog(MyClass myClassInstance)
{
this(); // pseudo-C#, i.e. how Delphi does it.
BindMyClassToTheDialog();
}
constructor MyClassDialog.Create(myClassInstance: MyClass);
begin
Create;
BindMyClassToTheDialog(myClassInstance);
end;
I think the Delphi syntax is clearer.
