c# - Check if directory exists with dynamic path -

how can check if directory exists dynamic path (~) not fixed path (c:)?

my code:

soin_id = request.querystring["soinid"]; string path = @"~\ordo\soin_"+soin_id+@"\"; if (directory.exists(path)) {     aspxfilemanager_ordo.settings.rootfolder = path; } else {     aspxfilemanager_ordo.settings.rootfolder =  @"~\ordo\"; } 

with condition, it's never true, though directory exists.

you need use server.mappath resolve dynamic path physical path on server.

if (directory.exists(server.mappath(path))) 

also consider using path.combine concatenation of path.
