Hi!
I am going crayz, i cant get this to work. and i don't know what the problem
is.
I have this method
public ArrayList ResolveData()
{
ArrayList workingList = new ArrayList();
Loop and stuff
// do stuff
workingList.Add (resolvedString .Split(new char[]{';', '--'});
loop ends here
return workingList
}
Then i have this method
private void MyPrivate()
{
ArrayList myArray = ResolveData();
foreach (ArrayList obj in myArray)
{
string[] resultSet = obj as string[]; <<<< This is where i get the
compile error.
}
}
What am i doing wrong?
Regards

This line:
foreach (ArrayList obj in myArray)
should just be:
foreach (string[] resultSet in myArray)
The way you've got it at the moment is expecting the ArrayList to be
full of other ArrayLists. There's no way of casting an ArrayList to a
string[], which is why you're getting a compile-time error.

Well you've got ArrayList in your foreach instead of string[]. Try
this:
System.Collecti ons.ArrayList a = new System.Collecti ons.ArrayList() ;
a.Add("this is a test".Split(' '));
a.Add("this is a test".Split(' '));
string[] s = (string[])a[0]; // <-- example normal cast
foreach(string[] ss in a) // <--- string array
{
Console.WriteLi ne(ss.Length);
}
Jon and DeveloperX have hopefully answered your original question; as
an additional - if you can, I strongly suggest moving to .Net 2.0 and
using generics, such as List<T>; because this is strongly typed, it
makes it absolutely clear what the problem is *at compile-time*,
rather than having to debug the issue at run-time.

Hi,
How can do runtime casting?
MyCollection derives from ArrayList
I will store lost of different objects that all derive from the same parent
class. I then want to be able to pass in the object type and collection type
I have a number of classes that derive from ArrayList and have if pick out
on ly those i asked for.

I have a class that contains an ArrayList object. All items in the arrayList
are of the same type, but that type depends on how the class is initialized.
I would like multiple public methods (with the same name) for retrieving my
objects WITHOUT having to have the caller cast them, i.e.
public OBJECT_TYPE1 GetAt( int arrayIndex )
{
return( (OBJECT_TYPE1) arrayList );
}

So I have an ArrayList that gets populated with objects like:
myAL.Add(new CustomObject(parm1,parm2));
I'm consuming this ArrayList from an ObjectDataSource and would like to have
this support sorting (because it's ultimately being consumed in a GridView).
I can't simply sort the ArrayList (because it only knows it's holding a
bunch of objects). So I need a way to sort the ArrayList, based on the
data - that is within the objects that...

Hello Everyone,
I just wanted to check that I'm using dynamic_cast correctly. I have a
hierarchy of objects using pure virtual classes and virtual inheritance
to implement interfaces. I ran into a problem using C-style casting to
an instance of a derived class from its interface type to a variable of
its concrete type. I was confused because I thought C-style casts
always compiled even if they wouldn't run correctly at runtime. I...
