Saving your work in C# .NET

Computer Tutorials List




When you save your work, C# will create quite a few folders and files for you. Click File from the menu bar at the top of the Visual C# Express software, then Save All:

File,  Save All menu

When you click Save All, you'll see the following dialogue box appear:

The Save Project dialogue box in C# .NET

You can type any name you like for your project. The default Name is ConsoleApplication1. Have a look at the location of the project, though:

C:\Users\Owner\documents\visual studio 2010\Projects

In XP, however, you'll see something like this:

C:\Documents and Settings\kayspc\My Documents\Visual Studio 2008\Projects

So it's going to be saved to the "documents" folder of this computer. In the "documents" folder you'll find another one called Visual Studio 2010. In this folder there will be one called Projects.

Before clicking the Save button, make sure there is a tick in the box for "Create directory for solution". Then click Save.

Now open up Windows Explorer (Hold down the Windows key on your keyboard, then press the letter "e"). Navigate to the folder location above. In the image below, we've used Windows Explorer to navigate to the Visual Studio 2010 folder:

Folders in the Documents library

Double click the Projects folder to see inside of it. Your should see a folder called ConsoleApplication1. Double click this folder and you'll see the following:

Folder View

So there's another folder called ConsoleApplication1. There's also two files: one that ends in sln, and one that ends in suo. The sln file is the entire solution. Have a look at the Solution Explorer again:

Solution Explorer

The one highlighted in blue at the top refers to the sln file. The suo file contains information about the Visual Studio environment - whether the plus symbols are expanded in the Solution Explorer, what other files you have open in this project, and a whole host of other settings. (If you can't see the suo file click Tools > Folder Option in Windows Explorer. In Vista and Windows 7, you may have to click Organise > Layout > Menu Bar first. Click the View tab, and select the option for "Show hidden files and folders".)

Double click your ConsoleApplication1 folder, though, to see inside of it:

Folders and files in the Console Application

Now we have three more folders and two files. You can see the bin and obj folders in the Solution Explorer:

Show all Files

Click ConsoleApplication1, second from the top. Then click the icon for Show all Files, circled in red in the image above. The bin and obj folders will appear. Click the plus arrows to see what's inside of these folders:

The bin and obj folders

The important one for us is the Debug folder under bin (there'll be an extra file ending in .manifest in c# 2010). You'll see why it's important in a moment. However, it's time to write some code!
