将文件保存在内存中，而不是物理路径

Question

I am trying to use Office Interop assembly to export a PowerPoint slide to an image. The SaveAs() , SaveCopyAs() , and Export() methods all accept a physical path as the output folder.

I want to put it in memory for further processing instead of creating a bunch of images on disks that I have to clear them later.

How can I export a slide and hold it in the memory temporarily instead of saving it in a physical folder?

Answer 1

Calling the Slide's .Copy method will put the slide on the clipboard in a number of formats, including PNG, GIF, JPG, DIB, BMP and metafile/enhanced metafile.

It should be possible to access the format you want from there.

Answer 2

There is no way of writing an Office Apps files straight to memory. You can look at Open XML SDK for Office, but i think, it will be easier if you just save the image to a file and load it through memorystream.
