(C#) How do you create a class with grouped properties/methods?

[Denaes]

I'm not sure how to explain it. I'm sure if I knew what it was called I could look it up :D

 

When I make a class, it generally looks like this:

 

public class Warehouse
	{
		// member variables
		private int numberOfItems = 0;
		private string manifestName = string.Empty;

		// Public Properties
		public int NumberOfItems
		{
			get
			{
				return numberOfItems;
			}
			set
			{
				numberOfItems = value;
			}
		}

		// Public Methods
		public void OpenManifest()
		{
		}

		public void CloseManifest()
		{
		}

		public void ClearManifest()
		{
		}
		
		public void NewManifest()
		{
		}
			
	}

 

so to access these methods, you have to type:

 

Warehouse wHouse = new Warehouse();
wHouse.ClearManifest;

 

you can see a few methods relating to a Manifests. There might be some related to Items, Deliveries, etc. Each would be their own class and the Warehouse class would be a superclass with code tying multiple other classes together.

 

I want to do this instead:

 

Warehouse wHouse = new Warehouse();
wHouse.Manifest.Clear;

 

I'd really like to learn how to do this, so if anyone can help, I'd appreciate it :)

public class Warehouse
{
	private  Manifest _manifest = new Manifest();
                         //-Expose private instance as read-only Manifest property.
	public  Manifest WarewouseManifest{
		get {
			return _manifest;
		}
	}

	public class Manifest{
	//-Manifest is public but non-creatable from other assemblies. If this is not requirement, then make internal public.
		internal Manifest(){}
		public void Clear(){}			
	}
}
}

and the name is nested class.

 

there is a good article in the help giving guidlines as to when to use and when not to use

Like I thought, they're different classes. But you declare a 'childClass' and expose it.

 

the 'internal' prevents it from being instantiated itself. If I'd realized this for my last project... I would have had 1000% nicer code... and probobly shaved off a few days of programming. :D
