Here's a recursive version that only requires one create and one delete:
(Use with caution it hasn't been tested that thoroughly)
bool CanCreate(string path)
{
try
{
var toCreate = new DirectoryInfo(path);
if(toCreate.Exists) return true;
var toDelete = MostGeneralMissing(toCreate);
toCreate.Create();
toDelete.Delete(true);
return true;
} catch {
return false;
// or throw if you prefer
}
}
DirectoryInfo MostGeneralMissing(DirectoryInfo dir)
{
if(dir == null || dir.Parent == null) return null;
if(dir.Exists == false && dir.Parent.Exists) return dir;
return MostGeneralMissing(dir.Parent);
}
It still has all the drawbacks from before though (i.e. if you don't have
delete privileges then you get a spare directory hanging around).
