Forgot Syntax: calling a parameterized constructor of the same class from a non-parameterized one

[Sathyaish]

/* I am writing this C# program because I forgot the syntax for
calling a parameterized constructor from a non-parameterized one
within the same class.

I was coding in Java and just typed it like this:

public MyClass(String someParam)
{
}

public MyClass()
{
this.MyClass("S omeparam");
}

The compiler complained and I remembered it was like this in Java:

public MyClass()
{
this("Someparam ");
}

This led me to think that I am forgetting the way it is done in C#
and that my mistake was influenced by the way it is done in C#. Just
so that I do not forget how to do it in C#, I am writing this small
spike solution as a reminder.

I have now tried

this.MyClass("S omeParam");
MyClass("SomePa ram"); and
this("SomeParam ");

None of them seem to work. What's the correct way. I realize I have
forgotten the correct way.

OK. RESOLVED.

It is

new SomeClass("Some Param");
Got it.

Test that and you'll see it isn't doing what you want. See my reply to your
original.

What you want is:

public MyClass() : this ("Someparam" )
{

See http://pobox.com/~skeet/csharp/constructors.html for this - along
with other differences between Java and C# when it comes to
constructors.

Thanks, Tom and Jon.

Ah! That was it. Thank you for the reminder, Tom. What I did earlier
was create a new object of the same class from an object of itself.
