c# - InitialDirectory not working -

very new c sharp, it's not part of study path, have edit small codes in c sharp in order app work. i'm using ogama, open source gaze tracker, need project. heatmap, more specific. now, want save heatmap directed folder, , managed find code. initial code was

 public static bool exportimagetofile(image image) {   savefiledialog dlg = new savefiledialog();   dlg.title = "please enter filename image...";   dlg.initialdirectory = environment.specialfolder.mydocuments.tostring(); 

so thought change it, following other tutorials online, , code.

public static bool exportimagetofile(image image) {   savefiledialog dlg = new savefiledialog();   dlg.title = "please enter filename image..."; dlg.initialdirectory = path.combine(environment.getfolderpath(environment.specialfolder.personal), "heatmapimages"); 

but doesn't work. when click save file button, brings me ogama projects are. 'heatmapimages' folder in desktop. advice? thank in advance. edit: managed make work, changing special.personal special.desktopdirectory. there way make autosave image? such don't need click save?

you need set restoredirectory true , set initialdirectory specialfolder.desktop. here specialfolders reference.

it restores current directory original value if user changed directory while searching files.
