I am getting an error when trying to build. Error is that ReneApp.Item does not contain a definition for Item and no extension method 'Item' accepting a first argument could be found. Any assistance would be greatly appreciated. I am new to C3 and this is my first try at a program.

using System;
using System.Collections;
using System.Linq;
using System.Text;

namespace ReneApp
{
    // Describes an item in the list:
    public struct Item
    {
        public string Status;       // Status of the item.
        public string Title;        // Title of the item.
        public string Series;       // Series the item is in.
        public string Author;       // Author of the item.
        public string Type;         // Type of item.
        public string Description;  // Description of item.

        public Item(string status, string title, string series, string author, string type, string description)
        {
            Status = status;
            Title = title;
            Series = series;
            Author = author;
            Type = type;
            Description = description;
        }
    }
    // Declare a type to process an item:
    public delegate void ProcessItemDelegate(Item item);

    // Maintains an item database.
    public class ItemDB
    {
        // List of all items in the database:
        ArrayList list = new ArrayList();

        // Add an item to the database:
        public void AddItem(string status, string title, string series, string author, string type, string description)
        {
            list.Add(new Item(status, title, series, author, type, description));
        }
        // Process items: 
        public void ProcessItem(ProcessItemDelegate processItem)
        {
            foreach (Item z in list)
            {
                if (z.Item)
                    processItem(z);
            }
        }
    }
}

// Using the Item class:
namespace ItemTestClient
{
    using ReneApp;

    class View
    {
        // Print the title of the item.
        static void PrintTitle(Item z)
        {
            Console.WriteLine("   {0}", z.Title);
        }

        // Execution starts here.
        static void Main()
        {
            ItemDB itemDB = new ItemDB();

            // Initialize the database with some items:
            AddItems(itemDB);

            // Print all the titles of items:
            Console.WriteLine("Item Titles:");
            // Create a new delegate object associated with the static 
            // method Test.PrintTitle:
            itemDB.ProcessItem(new ProcessItemDelegate(PrintTitle));
        }

        // Initialize the item database with some test items:
        static void AddItems(ItemDB itemDB)
        {
            itemDB.AddItem("Stock", "Dark Rival", "Masters of Time", "Brenda Joyce", "Book", "Time Travel");
            itemDB.AddItem("Stock", "Dark Prince", "Dark Series", "Christine Feehan", "Book", " ");
            itemDB.AddItem("Stock", "Shadow Game", "Ghost Walker", "Christine Feehan", "Book", " ");
            itemDB.AddItem("Stock", "The Quest", " ", "Lindsay McKenna", "Book", " ");
            itemDB.AddItem("Stock", "Rush Hour", "Rush Hour", "Jackie Chan", "Movie", "Action-Comedy");
            itemDB.AddItem("Stock", "The Long Kiss Goodnight", " ", "Samuel Jackson", "Movie", "Action");
            itemDB.AddItem("Stock", "Under Siege 2", "Under Siege", "Steven Seagal", "Movie", "Action");
            itemDB.AddItem("Stock", "Hostage", " ", "Bruce Willis", "Movie", "Action");
            itemDB.AddItem("Stock", "Tales of the Abyss", " ", " ", "Game", "Order of Lorelei");
            itemDB.AddItem("Loan", "The Curse of the Black Pearl", "Pirates of the Caribbean", "Johnny Depp", "Movie", " ");
            itemDB.AddItem("Wishlist", "Hidden Currents", "Drake Sisters", "Christine Feehan", "Book", "Book 7");
        }
    }
}

Your structure Item contains Status, Title, Series, Author, TYpe and Description. It has a method called Item, but you are using it as a Property in line 47. Not sure what you are trying to do with that line, so can't suggest a fix :)

BTW, it would be helpful if you specified which line was causing the error in the future, so we don't have to hunt for it.

I apologize. Line 49, Col 23. I believe it is erroring out on the a that I am using for Item. As I followed some coding from Microsoft, I am not sure why it is not working with a.Item.

As I said, your structure doesn't contain an Item property. Whatever code you were following does contain an Item property.

What is that code supposed to do? Why are you checking Item?

Basically, I am just trying to get the first part of a project completed. I am using the test part to put some books, dvd's, etc in to test the rest. I am trying to use this to display a complete list of those items. After I accomplish this, I will add other things after making it a windows app instead of a console.

After reviewing again, my issue is definately with a.Item. I will try to see if I can figure a way to print the entire list with this statement.

I think I have it now. I added another field that is boolean.
