c# - Detect the location of AppData\LocalLow -

i'm trying locate path appdata\locallow folder.

i have found example uses:

string folder = "c:\users\" + environment.username + @"\appdata\locallow"; 

which 1 tied c: , users seems bit fragile.

i tried use

environment.getfolderpath(environment.specialfolder.localapplicationdata) 

but gives me appdata\local, , need locallow due security constraints application running under. returned blank service user (at least when attaching process).

any other suggestions?

the environment.specialfolder enumeration maps csidl, there no csidl locallow folder. have use knownfolderid instead, shgetknownfolderpath api:

void main() {     guid locallowid = new guid("a520a1a4-1780-4ff6-bd18-167343c5af16");     getknownfolderpath(locallowid).dump(); }  string getknownfolderpath(guid knownfolderid) {     intptr pszpath = intptr.zero;     try     {         int hr = shgetknownfolderpath(knownfolderid, 0, intptr.zero, out pszpath);         if (hr >= 0)             return marshal.ptrtostringauto(pszpath);         throw marshal.getexceptionforhr(hr);     }         {         if (pszpath != intptr.zero)             marshal.freecotaskmem(pszpath);     } }  [dllimport("shell32.dll")] static extern int shgetknownfolderpath( [marshalas(unmanagedtype.lpstruct)] guid rfid, uint dwflags, intptr htoken, out intptr pszpath);
