.NET/C# Local AppData Handling

Writing to the application directory (Program Files) can be a problem, so here's how you define an AppData path.

C#

private static string appdatapath = Environment.GetFolderPath(Environment.SpecialFolder.LocalApplicationData);
private static string AppDataFolder = string.Format(@"{0}\{1}\{2}", appdatapath, "thronic.com", "ProgramName");
private static string LogFile = string.Format(@"{0}\{1}", AppDataFolder, "SomeLogFileOrOther.txt");

Creating the directory

if (!Directory.Exists(AppDataFolder))
	Directory.CreateDirectory(AppDataFolder);

It will create recursively (non-existing parent folders as well).
