How to transmit a zip file from c# code?

I'm not sure exactly why your snippet isn't working but here is a bit of code I'm using to do the same thing in my application. Hope it helps var updateFile = new FileInfo("path/to/file"); Response. ContentType = "application/octet-stream"; Response.

AddHeader("content-disposition", "attachment;filename=\"" + Path. GetFileName(updateFile. FullName) + "\""); Response.

AddHeader("content-length", updateFile.Length.ToString()); Response. TransmitFile(updateFile. FullName); Response.Flush().

1 You should specify the invariant culture in the call to ToString(). (updateFile.Length. ToString(CultureInfo.

InvariantCulture) – erikkallen Feb 4 at 14:27.

Try: HttpContext.Current.Response.ClearContent(); HttpContext.Current.Response.Clear(); HttpContext.Current.Response. AddHeader("Content-Disposition", "inline; filename=" + "test. Zip"); HttpContext.Current.Response.

ContentType = "application/zip"; HttpContext.Current.Response. BinaryWrite(ba); HttpContext.Current.Response.End(); Where ba is your byte array representing the zip file.

But that means loading the file into memory, which won't scale as well as just streaming it from disk – Rup Feb 4 at 13:52.

I'm using this: Response. ContentType = "application/zip" ; Response. AddHeader("content-disposition", "attachment; filename=" + HttpUtility.

UrlEncode(System.IO.Path. GetFileName(path))); Response. WriteFile(path); Response.End(); where the variable path is the full path of the (local) file.

Try adding Response.End() on the end of your script.

When I add this, I am getting an exception saying "ThreabAborted exception". – asd Feb 4 at 13:46.

I think there will be something wrong in returning the file that are zipped, if you are using jscript. If not then you are not properly returning the files name that being zipped. I have also done like this, make zipped file and then download it.

I used c#, jscript and asp.net. And it worked perfect for me. I pass the file/files to a jscript file, and jscript call a method to zipped the files, when zipping is being completed on server, the server return it to the client and start download automatically.

I don't know what machine you are using ... but windows releases before Vista use the FAt32 encoding for zip files, with Vista Microsft started to use NTFS as a file format. Please review your archive file format because I've faced a very similar situation when the user had a XP OS and I was creating the archive in win7 (the error message was the same you've posted). Best regards.

I don't think that would matter. The . Zip is independent of the filesystem that it was created on: the only possible difference between a zip created from FAT32 and from NTFS is that you could add the NTFS file permission data in as metadata, in the same way that Unix permissions get stored.

But these shouldn't interfere with non-NTFS systems. – Rup Sep 13 at 11:12.

I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
