I’m developing a small C# Winforms game and one of the things I’m wanting

  • 0

I’m developing a small C# Winforms game and one of the things I’m wanting to do is save application specific data. However, I’m struggling a bit to understand the correct place this should be stored.

As far as I can see there are several types of data an application might store and accordingly different places for it to be held:

1. Application properties
– Settings such as where the application stores it’s data, who the last logged in user was, the default window size, position etc. Is this information suppose to go into app.settings, or perhaps into the registry?

2. Global application data
– This might include sprites and other game assets that are used by every user that runs the application on this machine. Where would this common data be stored? It’s worth noting that in my particular case this data will not be provided with a default install and users will be allowed to add their own game assets which should be then available to any other user on the same computer.

3. User specific application data
– This would include a users saved game files, their specific application preferences and their profile information. Where should I be storing this?

Ideally I wish my application to be compatible with Windows XP, Vista, 7 and of course the upcoming Windows 8 – I don’t know if this changes the methods but hopefully it will assist with providing advice.

This is my first foray into this kind of development and I would appreciate some ‘best practice’ advice.

    Question 2:
    I suggest using a subfolder in Environment.SpecialFolder.CommonAppData (maps to C:\ProgramData on Windows7 by default). This is a hidden folder.

    Question 3:
    Put those files into Environment.SpecialFolder.AppData(maps to C:\Users\[USERNAME]\AppData\Roaming by default, hidden folder), if you expect that the user does not intend to backup / modify those. Some games also put their save games into Environment.SpecialFolder.MyDocuments, probably because it is easier for users to find them there.

    Example code:

    var directory = Environment.GetFolderPath(Environment.SpecialFolder.AppData);


using (FileStream fs = File.Create(Path.Combine(directory, "myAppDirectory", "myFile.txt")))
{
    // write data               
}
