WSDL and Optional Parameters

[WHY]

Since there's no way to create a c# method with optional, or nullable
parameters.

And since you can't write an overloaded web method.

Is it possible to edit the WSDL in conjunction with a c# method to make the
parameter optional, or have a default value at the client consumer?

Hi WHY,

You tapped out: <<

No sprintf ( char * Format, ... ) ?

You added: <<

Could that be true ? I don't believe it.

You asked: <<

Perhaps you could emulates sprintf() by parsing
a string that tells you what parameters are on the stack...

What's a stack ? I hear you asking.

It's a dynamic FILO queue, First In Last Out.

You could create a dynamic FILO queue via a dynamic array,
with pointers to the top and the bottom of the stack.

Of course I would use realloc() to manage a dynamic array...

But I think C#'s automatic allocations
could do something similar... perhaps using the VAR type.

You rant and spew acuneiform you want so much to be a c# programmer so you
can get a job.

But let me tell you -- there is only one real language: Graffiti 2 and it's
part of the Palm OS. I spend the whole weekend learning the little
cuneiform symbols and it was very cool.

I can sync up Linux with KPilot -- no problem.

..NET has a Stack class:

Stack s = new Stack();
s.Push(42);
int i = (int)s.Pop();

Hi Thomas Edison,

You mentioned: << .NET has a Stack class:
Stack s = new Stack(); s.Push(42);
int i = (int)s.Pop(); >>

How would that Stack class be added in C# or C++ ?

In C/C++ I would do something like this:
#include <Something.H> // Something.LIB

Well, the stack class is in the System.Collecti ons namespace - but that
resides in System.dll so, you don't actually have to do anything to add
it. If you want to access it with an unqualified name you have to place
a using statement in the file:

using System.Collecti ons;
....

Stack stack = new Stack();

Other wise you would have to write the code like this:

System.Collecti ons.Stack stack = new System.Collecti ons.Stack();

Hi Tom Shelton,

Re: System.Collecti ons.Stack stack
= new System.Collecti ons.Stack();

Upon compiling that in a .CPP file, I got this error:

'System' : undeclared identifier

Re: using System.Collecti ons;

That give me the following errors:

1. missing ';' before '.'

2. 'System' cannot be used in a using-declaration

For managed C++ you have to write
using namespace System::Collect ions;
If memory serves.

Different concept. ... is analgous to the params keyword in C#

public void sprintf(string format, params string[] parameters);

would work. However, its not the same as a VB optional parameter or an SQL
style nullable type. C# gains the latter in 2.0.

I do'nt know if params maps to WSDL or not.

WSDL works based on names, you cannot create overloads because the message
name determines which method is called. Two methods with teh same name
clash. I don't know the specifics but there is an attribute that will allow
you to change the method name.
Of course I would use realloc() to manage a dynamic array...

There *is* no VAR type, please learn the langauge before responding, -_-.
ArrayList, Stack, Queue, etc handle it for you. There is no simple
reallocation operation like C provides as it isn't always really logical to
do so, writing a dynamic array class isn't terribly hard, even if it is a
waste of time.
