问题
I load a multiframe TIFF from a Stream in my C# application, and then save it using the Image.Save method. However, this only saves the TIFF with the first frame - how can I get it to save a multiframe tiff?

Since you don't provide any detailed information... just some general tips:
Multi-Frame TIFF are very complex files - for example every frame can have a different encoding... a single Bitmap/Image can't hold all frames with all relevant information (like encoding and similar) of such a file, only one at a time.
For loading you need to set parameter which tells the class which frame to load, otherwise it just loads the first... for some code see here.
Similar problems arise when saving multi-frame TIFFs - here you need to work with EncoderParameters and use SaveAdd etc. - for some working code see here.
