El cuadro de diálogo carpetabrowser es un contenedor alrededor de una llamada API de Windows que no coincide con todas las rutas relevantes posibles (supongo que sería una tarea cuesta arriba ...) sin embargo, esto puede imitarse usando su propia clase. Generar la siguiente clase dentro de su aplicación (la adición de espacio de nombres y System.Reflection)
public class RootSetter
{
[Flags()]
public enum CsIdl
{
Desktop = 0x0000, // Desktop
Internet = 0x0001, // Internet Explorer (icon on desktop)
Programs = 0x0002, // Start Menu\Programs
Controls = 0x0003, // My Computer\Control Panel
Printers = 0x0004, // My Computer\Printers
Personal = 0x0005, // My Documents
Favorites = 0x0006, // user name\Favorites
Startup = 0x0007, // Start Menu\Programs\Startup
Recent = 0x0008, // user name\Recent
SendTo = 0x0009, // user name\SendTo
BitBucket = 0x000a, // desktop\Recycle Bin
StartMenu = 0x000b, // user name\Start Menu
MyDocuments = 0x000c, // logical "My Documents" desktop icon
MyMusic = 0x000d, // "My Music" folder
MyVideo = 0x000e, // "My Videos" folder
DesktopDirectory = 0x0010, // user name\Desktop
Drives = 0x0011, // My Computer
Network = 0x0012, // Network Neighborhood (My Network Places)
Nethood = 0x0013, // user name\nethood
Fonts = 0x0014, // windows\fonts
Templates = 0x0015,
CommonStartMenu = 0x0016, // All Users\Start Menu
CommonPrograms = 0x0017, // All Users\Start Menu\Programs
CommonStartup = 0x0018, // All Users\Startup
CommonDesktopDirectory = 0x0019, // All Users\Desktop
AppData = 0x001a, // user name\Application Data
PrintHood = 0x001b, // user name\PrintHood
LocalAppData = 0x001c, // user name\Local Settings\Applicaiton Data (non roaming)
AltStartup = 0x001d, // non localized startup
CommonAltStartup = 0x001e, // non localized common startup
CommonFavorites = 0x001f,
InternetCache = 0x0020,
Cookies = 0x0021,
History = 0x0022,
CommonAppdata = 0x0023, // All Users\Application Data
Windows = 0x0024, // GetWindowsDirectory()
System = 0x0025, // GetSystemDirectory()
ProgramFiles = 0x0026, // C:\Program Files
MyPictures = 0x0027, // C:\Program Files\My Pictures
Profile = 0x0028, // USERPROFILE
SystemX86 = 0x0029, // x86 system directory on RISC
ProgramFilesX86 = 0x002a, // x86 C:\Program Files on RISC
ProgramFilesCommon = 0x002b, // C:\Program Files\Common
ProgramFilesCommonx86 = 0x002c, // x86 Program Files\Common on RISC
CommonTemplates = 0x002d, // All Users\Templates
CommonDocuments = 0x002e, // All Users\Documents
CommonAdminTools = 0x002f, // All Users\Start Menu\Programs\Administrative Tools
AdminTools = 0x0030, // user name\Start Menu\Programs\Administrative Tools
Connections = 0x0031, // Network and Dial-up Connections
CommonMusic = 0x0035, // All Users\My Music
CommonPictures = 0x0036, // All Users\My Pictures
CommonVideo = 0x0037, // All Users\My Video
Resources = 0x0038, // Resource Direcotry
ResourcesLocalized = 0x0039, // Localized Resource Direcotry
CommonOemLinks = 0x003a, // Links to All Users OEM specific apps
CdBurnArea = 0x003b, // USERPROFILE\Local Settings\Application Data\Microsoft\CD Burning
ComputersNearMe = 0x003d, // Computers Near Me (computered from Workgroup membership)
FlagCreate = 0x8000, // combine with CSIDL_ value to force folder creation in SHGetFolderPath()
FlagDontVerify = 0x4000, // combine with CSIDL_ value to return an unverified folder path
FlagNoAlias = 0x1000, // combine with CSIDL_ value to insure non-alias versions of the pidl
FlagPerUserInit = 0x0800, // combine with CSIDL_ value to indicate per-user init (eg. upgrade)
FlagMask = 0xFF00, // mask for all possible flag values
}
public static void SetRootFolder(System.Windows.Forms.FolderBrowserDialog fbd, CsIdl csidl)
{
Type t = fbd.GetType();
FieldInfo fi = t.GetField("rootFolder", BindingFlags.Instance | BindingFlags.NonPublic);
fi.SetValue(fbd, (System.Environment.SpecialFolder)csidl);
}
y luego dentro de su clase llamada al configurar la carpeta raíz utilice la sintaxis siguiente. Sería mejor verificar la enumeración de un valor cercano en caso de encontrar uno, pero si no se puede, entonces el siguiente es bastante genérico y me permite moverme a través de mi disco C con bastante facilidad.
private void button1_Click(object sender, EventArgs e)
{
FolderBrowserDialog folderBrowser = new FolderBrowserDialog();
folderBrowser.Description = "Select Chase 6 Installation Folder";
folderBrowser.RootFolder = Environment.SpecialFolder.ProgramFiles;
folderBrowser.ShowNewFolderButton = false;
if (Directory.Exists(Properties.Settings.Default.defaultChasePath))
{
string x = Properties.Settings.Default.defaultChasePath;
//Use API Flag to set correct path, following tahter a catch all better to check
//enum for full list
RootSetter.SetRootFolder(folderBrowser, RootSetter.CsIdl.FlagDontVerify);
folderBrowser.SelectedPath = x;
}
if (folderBrowser.ShowDialog(this) == DialogResult.OK)
{
string huz = folderBrowser.SelectedPath;
}
}
Espero que ayude :)
