I am trying to create a class that contains a list of "items" within it. Which I have successfully done, however then I would like to create a list of items within the list of items. I have also been able to do this however I had to use a different name for the class within the item.
I would like to use the same class name as this will be used to generate some json where the class name is important. In addition I would like to be able to do this in a way where it could be recursive like a folder structure. All the properties would be the same for each. I hope I am explaining this well enough. I am essentially trying to create a folder / file structure where there can be x number of files in each folder that can also have x number of folders and so forth.
For example:
DocLib
-Item
--Item.Items
---Item.Items.Items
--Item.Items
-Item 2 etc...
Here is the existing code:
public class DocLib
{
public string Title { get; set; }
public string spriteCssClass { get { return "rootfolder"; } }
public List<item> items { get; set; }
public DocLib()
{
items = new List<item>();
}
public class item
{
public string Title { get; set; }
public string spriteCssClass { get; set; }
public List<document> documents { get; set; }
public item()
{
documents = new List<document>();
}
public class document
{
public string Title { get; set; }
public string spriteCssClass { get; set; }
}
}
}
I am sure there is probably a better way of implementing this.
Just let items be a list of your "own" type
public class DocLib{
public string Title { get; set; }
public string spriteCssClass { get { return "rootfolder"; } }
List<DocLib> _items;
public DocLib(){
_items = new List<DocLib>();
}
public List<DocLib> Items {
get{
return _items;
}
}
}
EDIT usage sample:
public static class DocLibExtensions {
public static void Traverse(this DocLib lib,Action<DocLib> process) {
foreach (var item in lib.Items) {
process(item);
item.Traverse(process);
}
}
}
class Program {
static void Main(string[] args) {
DocLib rootDoc = new DocLib {Title = "root"};
rootDoc.Items.Add( new DocLib{ Title = "c1" });
rootDoc.Items.Add(new DocLib { Title = "c2" });
DocLib child = new DocLib {Title = "c3"};
child.Items.Add(new DocLib {Title = "c3.1"});
rootDoc.Items.Add(child);
rootDoc.Traverse(i => Console.WriteLine(i.Title));
}
}
You could also do this with generics.
public class DocLib<T>
{
public T Item { get; set; }
public IEnumerable<DocLib<T>> Items { get; set; }
}
public class Item
{
public string Title { get; set; }
public string spriteCssClass { get; set; }
}
//Usage
//Set up a root item, and some sub-items
var lib = new DocLib<Item>();
lib.Item = new Item { Title="ABC", spriteCssClass="DEF" };
lib.Items = new List<DocLib<Item>> {
new DocLib<Item>{ Item = new Item {Title="ABC2", spriteCssClass="DEF2"} },
new DocLib<Item>{ Item = new Item {Title="ABC3", spriteCssClass="DEF3"} }
};
//Get the values
var root = lib.Item;
var subItems = lib.Items.Select(i=>i.Item);
