memorystream

I need to export multiple files with varying file types (pdf, xlsx, .docx) stored in a database (Byte Array) and save them as a single zipped file. How should I handle the multiple files? I’m assuming I would need to first store the files in a list and using MemoryStream? I’m using the ZipArchive class to export the files as a zip file. Assuming this approach will work, I’m unsure of how to pass the list as an argument to the ZipArchive (DownloadMultipleFiles) method.

I’m using the below sample code for writing and downloading a memory stream to a file in C#.
