c# - File permission (write) -

hello,
once got code work out erros, , downloaded file.
gives me permission error,
don't acesscontrol pop window should show.
anyways,
how can code download file?

webclient request = new webclient(); request.credentials = new networkcredential(txtftpuser.text, txtftppassword.text); byte[] filedata = request.downloaddata(fulldownloapath);//dnoces.dreamhost.com filesecurity security = file.getaccesscontrol(downloadto);  filesystemaccessrule rule = new filesystemaccessrule(@"builtin\users",      filesystemrights.fullcontrol, accesscontroltype.allow);  file.setaccesscontrol(downloadto, security); try {     filestream f = file.create(downloadto/*+@"\"+file*/);     f.write(filedata, 0, filedata.length);     f.close();     messagebox.show("completed!"); } catch(exception e) {     messagebox.show(e.message); } 

what in 'downloadto' variable ? i'm little confused code. since can perform getaccesscontrol() assume must contain folder. if file, fail because doesn't exist yet.

but code continues

filestream f = file.create(downloadto/*+@"\"+file*/); 

since wrote /* */ 'file' variable commented, makes me assume downloadto must contain full path including filename.

can try , hardcode destination file ?

(e.g. filestream f = file.create(@"c:\\users\\your user\\myfile.bin");

as far can interpret code you're trying write folder such without specifying filename.
