sharpziplib

问题 I am using SharpZipLib in a project and am wondering if it is possible to use it to look inside a zip file, and if one of the files within has a data modified in a range I am searching for then to pick that file out and copy it to a new directory? Does anybody know id this is possible? 回答1: Yes, it is possible to enumerate the files of a zip file using SharpZipLib. You can also pick files out of the zip file and copy those files to a directory on your disk. Here is a small example: using (var

问题 I get the following exception when I open a file for unzipping it's contents. It happens when I have the file selected in Windows Explorer, or mouse over it showing a tooltip.

问题 I am developing wpf application. I am using sharpziplib to compress and decompress files. I am easily decompress the .zip files using following code public static void UnZip(string SrcFile, string DstFile, string safeFileName, int bufferSize) { //ICSharpCode.SharpZipLib.Zip.UseZip64.Off; FileStream fileStreamIn = new FileStream(SrcFile, FileMode.Open, FileAccess.Read); ZipInputStream zipInStream = new ZipInputStream(fileStreamIn); string rootDirectory = string.Empty; if (safeFileName.Contains

问题 New to C#, I'm developing a windows form application inside visual studio. The app uses ICSharpCode.SharpZipLib library to update a zip's content. When the zip file is inside a non system partition, say like D:\myzip.zip the files gets updated correctly. But, if the zip is in the system partition, C:\myzip.zip the app returns an error; Could not find file C:\myzip.zip even though the file is there! This has to do with admin privileges because when I run the app as administrator it works. The

问题 I am using ICSharpCode.SharpZipLib.Zip to compress the files and folders and pass it as memorystream using response.Binary write. Here is my code: MemoryStream df= new MemoryStream(); ZipOutputStream s = new ZipOutputStream(df); s.SetLevel(9); byte[] data = (byte[])file.OpenBinary(); s.Write(data, 0, data.Length); s.Finish(); s.Close(); byte[] outBuf = df.GetBuffer(); Response.Expires = 0; Response.Buffer = true; Response.ClearContent(); Response.AddHeader("content-disposition", "inline;

问题 From examples, I've got a pretty good grasp over how to extract a zip file. In nearly every example, the method of identifying when a ZipEntry is a directory is as follows string directoryName = Path.GetDirectoryName(theEntry.Name); string fileName = Path.GetFileName(theEntry.Name); if (directoryName.Length > 0) Directory.CreateDirectory(Path.Combine(destinationDirectory, directoryName)); if (fileName != String.Empty) { //read data and write to file } Now is is fine and all (directory

问题 I am creating a list of ExcelPackages (xlsx documents) using EPPlus, and adding them to a ZipOutputStream as ZipEntries. I think the Excel documents should be valid, as I can open them just fine when I write one of them to the Response object without zipping. The zip folder is created as expected, and the file(s) are there and doesnt seem to be empty, but when I try to open them I get the following error in Excel: Excel cannot open the file {Name}.xlsx because the file format or file

问题 I'm very sorry for the conservative title and my question itself,but I'm lost. The samples provided with ICsharpCode.ZipLib doesn't include what I'm searching for. I want to decompress a byte[] by putting it in InflaterInputStream(ICSharpCode.SharpZipLib.Zip.Compression.Streams.InflaterInputStream) I found a decompress function ,but it doesn't work. public static byte[] Decompress(byte[] Bytes) { ICSharpCode.SharpZipLib.Zip.Compression.Streams.InflaterInputStream stream = new ICSharpCode

问题 I am trying to .tar.gz a list of files from a folder using SharpZipLib. The problem is no matter how pass the files paths - the result always contains the files paths - and not only the files thems selves. What am i missing here? string filesFolder = "c:\\testfolder\\test\\"; List<string> filesToZip = new List<string>() { filesFolder +"test1", filesFolder +"test2"}; using (FileStream fs = new FileStream(filesFolder +"myGz.tar.gz" , FileMode.Create, FileAccess.Write, FileShare.None)) using

问题 With the SharpZip lib I can easily extract a file from a zip archive: FastZip fz = new FastZip(); string path = "C:/bla.zip"; fz.ExtractZip(bla,"C:/Unzips/",".*"); However this puts the uncompressed folder in the output directory. Suppose there is a foo.txt file within bla.zip which I want. Is there an easy way to just extract that and place it in the output directory (without the folder)? 回答1: The FastZip does not seem to provide a way to change folders, but the "manual" way of doing
