Why isn't my public ArrayList available to other modules?

namespace RocketDyneVegetable
{


public partial class InheritedVegetableForm : RocketDyneVegetable.BaseVegetableForm
{
LineItem li;


public ArrayList LineItems = new ArrayList();
....

I currently have a public ArrayList defined in a Windows Forms class file. However, although the ArrayList is public, it's not showing up as available anywhere else in the solution. Why is this, or is there a way to work around it?

Please help out a new bee.

I've also tried setting up a static class in the project that contains the ArrayList, since I only need to use one at a time. But that doesn't work either. What am I doing wrong?

The static class itself is Intellisensed elsewhere in the project, but the only attributes I can select it are .Equals and .ReferenceEquals.

I need to have a popup form containing a DataViewGrid that I want to populate from LineItems, but there seems to be no way to access it except from within the module that created it.





(Static class definition)
...

using System.Collections;

namespace RocketDyneVegetable
{

static class LineItemsCollection
{

static ArrayList LineItems = new ArrayList();
}
}

OK, I finally got this straight. By adding the 'public' access modifier to the arraylist definition, it's being recognized properly now.

So now the static class looks like this.
CODE

{

    static class LineItemsCollection
    {

        public static ArrayList LineItems = new ArrayList();
    }
}


For some reason I thought I'd tried that already and it hadn't compiled.

here is the more "normal" way of doing what you want.

C#

    static class LineItemsCollection
    {
        private ArrayList m_listItems = new ArrayList();

        public ArrayList ListItems
        {
            get { return m_listItems; }
            set { m_listItems = value; }
        }
    }


and to access/set the data from outside the class:

C#

ArrayList arrList = new ArrayList();

LineItemsCollection lineItemCollection = new LineItemsCollection();
lineItemCollection.ListItems = arrList;

            set { m_listItems = value; }
        }
    }


Does this compile for you? When I do it in Visual Studio, I get an error message that I can't declare instances in a static class. It does compile if I declare the ArrayList and its property as static.

Sorry, try this:

C#

    public class LineItemsCollection
    {
        private ArrayList m_listItems = new ArrayList();

        public ArrayList ListItems
        {
            get { return m_listItems; }
            set { m_listItems = value; }
        }
    }
