Assign Arraylist into Arraylist

[Grey]

i have succeed to assign one ArrayList into another ArrayList, i.e.
PcNameVirusDef.Add (Rec[0].ToString());
PcNameVirusDef.Add (Rec[4].ToString());
arPcNameVirusDef.Add(PcNameVirusDef);

But when I try out extract back the value, i.e.
arPcNameVirusDef[0][0].toString();
I got error....In fact, how to get the value and is it possible to do that in C#...as I tried this approach with Collection in VB6..

If I understand your objective, I thing using
arPcNameVirusDef.Addrange(PcNameVirusDef); should work for you.

You can do anything in C# that you can with VB.NET with very limited
exceptions, but I'm not sure what the ultimate goal is...let me know and
I'll walk you through it.

HTH,

Bill

Hi Grey,

The ArrayList returns an object for the indexer, so you have to cast it
back

String s = (string)((ArrayList)arPCNameVirusDef[0])[0];

Or for easy reading.

object o = arPCNameVirusDef[0];
ArrayList a = (ArrayList)o;

o = a[0];
String s = (string)o;

Happy coding!

If you do this, think about the
System.Collections.Specialized.StringCollection for a type-safe string
collection.
