How to load Word document from memory instead of local file system? | [VSTO C# Add-in]

Ironshaktimaan 1

I'm creating a VSTO Add-in for Word in C#.
I have a document downloaded into memory from a server as byte array. I need to load that document present in memory as byte array without saving it on the disk. Is it possible? If so, how?

Thanks in advance.

Probably this is not a supported scenario because Word normally expects a real file that has name, date, etc.

Although, maybe it is possible to embed a document. (For example, Word can open and edit a document that is embedded into an Excel workbook).

Or maybe you can create a virtual file (https://learn.microsoft.com/en-us/windows/win32/projfs/projected-file-system) and supply its contents from your array.

Perhaps there are other simpler solutions.

Alternatively, you can simply write the array to disk (or avoid the array), and focus on main features.
