C# - unable to return List

Question

i'm trying to return list of objects from a class and get the following error:

Error 1 Inconsistent accessibility: property type 'System.Collections.Generic.List<EventXmlExtract.Attribute>' is less accessible than property 'EventXmlExtract.EventExtract.AttributeList' C:\Documents and Settings\eyalk\My Documents\Visual Studio 2010\Projects\Blobs\EventExtractDll\EventExtract.cs 14 32 EventExtractDll

my code tries return _attributeList:

public class EventExtract
{
    private string _type;
    private int _type_id;
    private List<Attribute> _attributeList = new List<Attribute>();

    internal List<Attribute> AttributeList
    {
        get { return _attributeList; }
        set { _attributeList = value; }
    }
}

what is the problem ? and how can i retrieve the list ?

What is the class Attribute? I stronly suspect that it's not the System.Attribute class — SWeko

then there's the problem. make that Attribute class at least 'internal' and the code will compile just fine — yas4891

Could you please show it's definition, as that is the root cause of the problem. — SWeko

Make the class Attribute public or internal.

You can't return a list of objects where the class is private, because then the calling code can't access the objects.

Alternatively make the AttributeList as restricted as the Attribute class, if that is how you want it.

Unless nested, classes can only be public or internal.

Your Attribute class lacks the required visibility.

change the class definition to either

public class Attribute
{

or

internal class Attribute 
{

Unless nested, those two are the only allowed access modifiers on a class element, anyway...

Makes you wonder how he ended up in that spot in the first place. For the default modifier is internal

I think the problem is that you have declared the property as private. Try making it as protected or public.

The property is not declared as private, it's internal. The problem is not that the property is too restricted, it's that the type that it returns is too restricted.

Did you include the following?

using System; using System.Collections.Generic;

The class compiles fine on my box... :)
