Generating a zipOutputstream from a folder having other .zip files in it

Posted By: watson     Posted Date: October 04, 2013    Points:5   Category :C#
I am trying to convert an entire azure blob storage folder and its contents to a zip file .Inside this folder ,I have different types of files eg, .txt,.mp3,.zip files .But once the folder is converted to zip file I noticed that all the .zip file types got corrupted,.How can I prevent my zip files from corrupted. I am using Ionic.Zip library to generate zip files

Here is the code I am using .Here I am able to generate and download the zip file successfully with all other filetypes *except the inner zip files*.


var allFiles = directory.ListBlobs(new BlobRequestOptions { UseFlatBlobListing = true }).Where(x => x.GetType() == typeof(CloudBlockBlob)).Cast<CloudBlob>();
string xyzblob = directory.Uri.ToString().TrimEnd('/');
var dBlob = blobClient.GetBlobReference(xyzblob);
byte[] fileBytes = null;
fileBytes = dBlob.DownloadByteArray();

foreach (var file in allFiles)
{
using (var fileStream = new MemoryStream(fileBytes))
{
var entryName = file.Uri.ToString().Replace(directory.Uri.ToString(), "");
zipOutputStream.PutNextEntry(entryName);
fileStream.Seek(0, SeekOrigin.Begin);
int count = fileStream.Read(fileBytes, 0, fileBytes.Length);
while (count > 0)
{
zipOutputStream.Write(fileBytes, 0, count);

count = fileStream.Read(fileBytes, 0, fileBytes.Length);
if (!Response.IsClientConnected)
{
break;
}
Response.Flush();
}
fileStream.Close();
}


}
zipOutputStream.Close();
