dotnetzip

问题 I am using DotNetZip and have noticed that i am getting permission issues on Mac's. This seems to only occur when i use content disposition. ie if i just save it to disk using (ZipFile zip = new ZipFile(@"C:\zip\temp.zip")) { // this works fine } but if i use content disposition like so, on mac the user permissions are denied ( everyone group is unchecked) Response.ContentType = "application/zip"; Response.AddHeader("content-disposition", "filename=" + filename); using (ZipFile zip = new

问题 I found out a problem in my project. I'm currently using a DotNetZip library to extract zip - files. Additionally, I need to delete a zip file after extracting it's content. However, I'm unable to do it (both manually and using File.Delete(...)), cause the folder is open in my programm. So, I think this problem is caused by file extraction process The "suspicious" code part: string localFileName = @"...path...."; string remoteDir = "/SFTPfolder/"; using (var sftp = new SftpClient(SFTPHost,

问题 Can someone helps me out with my problem. I have to take a file's directory in zip file so i can calculate its MD5 hash (without unzip it). I am using DotNetZip Library but i can't find the solution of the problem. I'll show you what i've tryed and hope you will help as fast as possible. Thanks! if (ofd.ShowDialog() == DialogResult.OK) { using (ZipFile zip = ZipFile.Read(ofd.FileName)) { foreach (ZipEntry f in zip) { GetMD5HashFromFile(ofd.FileName+"\\"+f.FileName); } } } 回答1: The problem is

问题 I can use the DotNetZip library to unzip a single zip file: Using Zip As ZipFile = ZipFile.Read(ZipFilePath) AddMessage("Unzipping " & Zip.Entries.Count & " entries") End Using However, if I try and pass in the first segment of a split archive produced using 7-Zip (e.g. Pubs.zip.001) then it throws an error: Could not read block - no data! (position 0x03210FCE) The documentation seems to infer that you don't have to do anything special to read a split archive: This property has no effect when

问题 I am trying to unzip a file with DotNetZip but I get a error on the "e" using (ZipFile zip = ZipFile.Read(openFileDialog1.FileName)) { foreach (ZipEntry e in zip) { e.Extract(Environment.CurrentDirectory, ExtractExistingFileAction.OverwriteSilently); } } 回答1: I suspect you are doing this inside an event handler which already has a parameter called e . Try renaming e to entry inside the foreach . 来源： https://stackoverflow.com/questions/16263099/error-a-local-variable-cannot-be-declared-in-this

问题 I create a zip file in a controller from a byte array and I return the zip file as a fileresult. When I download the zip File and extract the file, it is corrupt. I'm doing it this way: byte[] fileBytes =array MemoryStream fileStream = new MemoryStream(fileBytes); MemoryStream outputStream = new MemoryStream(); fileStream.Seek(0, SeekOrigin.Begin); using (ZipFile zipFile = new ZipFile()) { zipFile.AddEntry(returnFileName, fileStream); zipFile.Save(outputStream); } outputStream.Position = 0;

问题 I am using DotNetZip. Using it to zip mp3 files. ZipFile zip = new ZipFile(); zip.Password = "123"; zip.AddFile("R:\\abc\\a\\a 2 z.mp3"); zip.Save("R:\\abc\\a\\aaa.zip"); After extraction of aaa.zip, I get a corrupted mp3 file. Having 3.31MB data when original had 3.62MB. How to resolve this problem? Any help is appreciated. 回答1: The documentation states here: Be aware that the ZipFile class implements the IDisposable interface. In order for ZipFile to produce a valid zip file, you use use it

问题 I'm trying to extract data from compressed bytes from network capture file (PCAP.) Data from some of these packets don't have ZLIB header (the first 2 bytes, where lower 4 bits of first byte is always 8) and hence gave exception when I tried to decompress it using ZlibStream . Data with headers seem to work fine. As I understand that ZLIB is just a header and footer over DEFLATE, I pass these data without headers to DeflateStream . This time DeflateStream doesn't throw any error, it just gave

问题 I have files stored in one container within a blob storage account. I need to create a zip file in a second container containing the files from the first container. I have a solution that works using a worker role and DotNetZip but because the zip file could end up being 1GB in size I am concerned that doing all the work in-process, using MemoryStream objects etc. is not the best way of doing this. My biggest concern is that of memory usage and freeing up resources given that this process
