Array of classes

[Chad Z. Hower aka Kudzu]

Can u write a little delphi code to do what u r saying ?

I've solved it with Jon's help. Did you want the Delphi code just for
curiosity? If so I can write it.

Hi Chad,

Thanks. Is there any way to declare a type of my base class? Or is type
generic only? That is in Delphi I can do:

type
TMyClassType = class of TMyClass;

No, C# (and .NET as a platform)doesn't support the concept of meta classes
as Delphi does. Eventhough sometimes you can think of .NET Type objects as
Delphi meta classes this could be correct in some very-very few situations.
And because you don't have the Delphi concept of meta classes you don't have
virtual constructors and virtual static members.

This is just in the newsreader, so it might not compile but here is the
basic idea:

type
TFoo = class(TObject)
...
...
...
end;

TFoo1 = class(TFoo)
...
...
...
end;

TFoo2 = class(TFoo)
...
...
...
end;

TFooClass = class of TFoo;

Now I can make an array:

var
MyFoos: Array[0..1] of TFoo = (TFoo1, TFoo2);

Then later I can do

var
LFoo: TFoo;
begin
LFoo := MyFoos[0].Create;

Make sense? Its a lot cleaner in Delphi.

I did not and still do not understand your requirement despite reading
almost all the posts. But I will venture to give the following
suggestion

1. Create a class indexer
public class myIndexer
{
object[] o=new object[12];
public object this[int index]
{
get
{
return o[index];
}
set
{
o[index]=value;
}
}
}

2.
Assign the form1,form2 objects to the above class
myIndexer ob=new myIndexer();

ob[0]=form1;
ob[1]=form2;

3.

Convert them to form objects with

form1=(Form)ob[0];

etc.

I hope the above is what you have been looking for.
