Question

I have see this term branded around but I don’t really understand how you open a file in memory.

I have the files written to disk in a temp location but this needs cleaning when a certain form closes and I can’t do it when it’s open. It’s a must that this folder gets emptied. I was wondering if I opened files in memory instead whether it would make a difference?

Answer 1

MemoryStream inMemoryCopy = new MemoryStream();
using (FileStream fs = File.OpenRead(path))
{
  fs.CopyTo(inMemoryCopy);
}
// Now you can delete the file at 'path' and still have an in memory copy
