Start process from stream

Question

I have a memory stream that contains a PDF file.

Is it possible to view the PDF without saving it to the hard disk ? Process.Start() only takes a path and not a str

Answer 1

Only by implementing your own pseudo-file system in C#, somehow mounting this as a disk in Windows, and having it intercept the file open and stream the contents of your MemoryStream. Absolutely 100% certainly not worth the effort.
