[RESOLVED] Generate image path from unique name, what to do with invalid chars?

[NickThissen]

you can asign an unique id to the radio station and use that id as the image name

I thought of that but that is not an option, for other reasons. Perhaps as a last resort.

You have this kind of options. You can go for the

Path.GetTempFileName()

Creates a uniquely named, zero-byte temporary file on disk and returns the full path of that file.

System.Guid.NewGuid

to get a unique GUID

Or You can use the current time(with seconds) with that RadioButton to create unique id

System.DateTime.Now.ToString("ddMMyyyhhmmss")

The GetTempFileName creates a filename in the Temp folder, right? I don't want that. I suppose I could always use only the last part of the path (the actual filename), but that would leave me with the same problem I think. I suppose the GetTempFileName generates a unique name in the Temp folder, which doesn't have to be unique in my own folder. So if I take this route I may as well just generate my own random name and hope I never get a conflict.

I'll look into the Guid thing, never used that before.

The time is not an option, because the custom stations are all saved in one go, along with their images, so the images would all have the same timestamp.
