C# ArrayList access from other script

Questions & Answers
1

Ive got an error:

Cannot cast from source type to destination type.

when I try to use foreach in other script:

bInfo   = 	gameCore.GetComponent<bInfo>();
ArrayList boyList= bInfo.boyList;
foreach (PlayerNode entry in boyList){}

The list contains of:

public class PlayerNode
{
    public string name;
    public string id;
}

Generally you can extract elements from a collection of types using Linq.

Let’s say you have a collection that contains many different things and you just want the list of the ones that are PlayerNodes:

  using System.Linq;
  ...
  foreach(var entry in bInfo.boyList.OfType<PlayerNode>())
  {
  }

I’m not 100% sure that this is your problem as I can’t see the definition of boyList inside the bInfo script.
