推荐答案

添加对 System.IO.Compression.FileSystem

然后您可以使用以下命令压缩文件夹:

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)

然后下载它，你可以在响应中发送它:

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()
