Re: return object of an unknown type

Yes you can, but you should really have a very good reason for not
knowing in advance what the object type is.
Critically you need to understand a little about inheritence.
Everything in dotnet is derived from object, so a variable of type
object can hold anything. There are several ways of casting from one
type to another.

Here's some code.

object of;
object ot;
Form f = new Form();
TextBox t = new TextBox();

of=f;
ot=t;

f=null;
//cast example
f=(Form)of;

//this will throw an exception so commented out
//f=(form)ot;

//safe way of doing it.
f = of as Form;
if(null != f)
{
Console.WriteLine("of is a form");
}
//f should be null after this as ot points at a textbox
f = ot as Form;
if(null == f)
{
Console.WriteLine("ot is not a form");
}

hi,
is it possible to return an object of an unknown (but not really unknown)
type with an method?

i have the following situation:

- a variable (A) of the type "object" which contains the object
- a variable (B) of the type "Type" which contains the type of the object in
(A) (A should be of the type B)
- a method which should return the object (A) as type (B)

it sounds very simple, if you hard-code it, but it should be a little more
dynamic.

here something in c#-pseudocode:

object myobject = ...
Type typeofobject = ...

public typeofobject GetTheObject()
{
return (typeofobject) myobject;

}Could you help me please?

Thanks in advance,
Alex
