How do I use multiple *.cs files in C# Console app.

Posted 17 January 2011 - 02:35 PM

For a lesson at school I decided I would learn C# since I want to go on to programming, however not having all the time in the world to learn it all I have had to start making my program to show how I'm doing. This made me think of making a Text-Based game, since most of my programs before had been in the console. So that's the background stuff. Oh and please note that I've only been teaching myself this for about 2 months.

I've made a menu.cs which starts off the game, asking if they need to know how to play the game or not, when they want to start the game by typing "Start" I need it to run the code that I've placed in World.cs, since I'm keeping all my systems separate (Menu.cs, Items.cs, Entity.cs, Battle.cs and World.cs). Here's the code, but since I'm doing the framework of it, please ignore the lack of story or information for the main menu.

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using RPG.World;

namespace RPG.Menu
{
    public partial class Menu
    {
        static void Main()
        {
            Console.Title = "The Game Ver. 0.0.1";
            Console.CursorVisible = false;
            Console.WindowWidth = Console.LargestWindowWidth;
            Console.WindowHeight = Console.LargestWindowHeight;
            Console.WriteLine("Welcome traveler to the start of your adventure. To learn the controls type 'help' and press enter or just type 'start' to begin your adventure.");
            Boolean check = true;
            while (check == true)
            {
            string Input = Console.ReadLine();
            Input = Input.ToLower();
            

                if (Input == "help")
                {
                    check = false;
                    Help();
                }
                else
                {
                    if (Input == "start")
                    {
                        check = false;
                        ****

                    }
                    else
                    {
                        if (Input == "exit")
                        {
                            check = false;
                        }

                    }
                  
                }
                if (check == true)
                {
                    Console.WriteLine("What you entered wasn't recognised please enter Start, Help or Exit.");
                }
                else
                {

                }
            }

        }


the **** is where I need it to go to World.cs and start running the code in there. Which I haven't started on atm. But have Console.WriteLine("Start game in here"); so I know it's running that code, but I can't get it to work.

Sorry I forgot to mention that all the *.CS files are under one .csproj file thing. Sorry.
Thanks for anyone who's willing to help.

Right-click on the project and choose Add... New code file


I am going to guess that you are trying to teach yourself C# without much guidance, a decent book or without knowing where to look. Sometimes just knowing where to look can make all the difference. Google is your friend.
Search with either "C#" or "MSDN" as the first word: "MSDN Picturebox", "C# Custom Events", "MSDN timer" etc.

But honestly, just typing away and seeing what pops up in Intellisense is going to make your self-education take 20 years. You can learn by trying to reverse engineer the language through banging on the keyboard - or you can learn by doing the tutorials and following a good "How to learn C#" book.

May I suggest picking up a basic C# introductory book? It's not that people here don't want to be helpful, but there is a certain amount of basic learning work that one should really take upon themselves before asking for help. There are so many great "How do I build my first application" tutorials on the web... There are dozens of "Learn C# in 21 days", "My first C# program" books at your local book seller or even public library... Asking a forum, any forum, to hand-hold you through it is just redundant. In many ways it disrespects the people who have invested dozens of hours in the on-line tutorials and those that spent thousands of hours in authoring books.

Build a Program Now! in Visual C# by Microsoft Press, ISBN 0-7356-2542-5
is a terrific book that has you build a Windows Forms application, a WPF app, a database application, your own web browser.

C# Cookbooks
Are a great place to get good code, broken down by need, written by coding professionals. You can use the code as-is, but take the time to actually study it. These professionals write in a certain style for a reason developed by years of experience and heartache.

Microsoft Visual Studio Tips, 251 ways to improve your productivity, Microsoft press, ISBN 0-7356-2640-5
Has many, many great, real-world tips that I use all the time.

The tutorials below walk through making an application including inheritance, custom events and custom controls.
Quick and easy custom events
Bulding an application - Part 1
Building an application - Part 2
Debugging tutorial
Working with environmental variables

Writing a text file is always one of the first things people want to do, in order to store data like high-scores, preferences and so on
Writing a text file tutorial.

These are just good every-day references to put in your bookmarks.
MSDN C# Developers Center with tutorials
Welcome to Visual Studio

Re: How do I use multiple *.cs files in C# Console app.

Posted 17 January 2011 - 03:17 PM

It's not that I haven't got a book, I have 2, but since I don't have all the time I need to get through it all I had to just start some programming before I knew all of what I needed, I've programmed quite a few console apps. However, they have just been Number Theory, so I was getting use to using variables, and throwing them around. Unfortunately, as I can tell by your post you obviously think I need a lot more time than what I have, which I understand.

Also thanks for the post, I'll have a look through all the links and see what I can find in them and I did use google since I spent the past day searching, but I guess I don't entirely know what precisely I'm looking for.

As I said thanks for the post I'll put off the main bit till I get a bit more learnt and am able. :)
