In aspx.vb file:

How can I write code here that will zip a folder on my desktop and start downloading this zip folder? Is there way to do it without downloading extra libraries and plugins?

Answer 1

Add a reference to System.IO.Compression.FileSystem

Then you can zip the folder using the following:

Dim tempFile = System.IO.Path.GetTempFileName() + ".zip"
System.IO.Compression.ZipFile.CreateFromDirectory("C:\temp\awesome", tempFile)

Then to download it, you can send it in the response:

Response.Buffer = false
Response.Clear()
Response.AddHeader("content-disposition", "attachment;filename=Desktop.zip")
Response.ContentType = "Application/zip"
Response.TransmitFile(tempFile)
Response.End()
