问题
My application (written in WPF/C#) will monitor a live video source and will need to store small video segments and image stills. I'm hesitant to use a user defined "temp" directory since this would potentially allow a user to modify or delete these files causing major issues with my application. Alternatively, I have attempted to store these items in memory (BitmapSource object for the images) but cannot find an equivalent object for video. Should I byte the bullet and use a temp directory and simply use the image's URI or is their a better approach? Thank you in advance!
回答1:
Couldn't you use the appdata store rather than a user-elected store?
System.Environment.GetFolderPath(Environment.SpecialFolder.LocalApplicationData)
回答2:
Maybe you want to look at Isolated Storage provided by .NET
That should do the job I think..

What we do.. Ideally, we store the images on a sercure remote server(like a dvr). when this is not possible. an encyption alog.. is used to store (save and load) the images to prevent any tampering.
