As described in this article for a C # using Icsharpcode compression of the use of the class, the test results are good. Share it for everyone's reference. Here's how:


1. Parameter classes

Using system;using system.collections.generic;using system.linq;using system.text;namespace ZipCompress{public  Class Zipparameter  {    private string zip_name = "";    private string zip_directoryname = "";    Private list<string> zip_filelist = new list<string> ();    <summary>///    Compressed file name///    </summary> public    string zipname    {      get {return zip_ Name; }      set {zip_name = value;}    }    <summary>///    Compressed file path///    </summary> public    string zipdirectoryname    {      get { return zip_directoryname; }      set {zip_directoryname = value;}    }    <summary>///    Compressed file list///    </summary> public    list<string> zipfilelist    {      get {return zip_filelist;}      set {zip_filelist = value;}}}}  


2. Working class

Function: Implement file compression// How to: Set Parameters for compression//*****************************************************************************************using System;using icsharpcode.sharpziplib.zip;using system.io;using system.text;namespace ZipCompress{public class Compressfile {//<summary>///Compressed file parameters///</summary> public zipparameter zipparameter {get; SE T }///<summary>///Compressed file returns compressed information///</summary>//<returns>string Returns the message after compression &LT;/RETURNS&G    T      public string compressreturnmsg () {FileStream zip_file;      Zipoutputstream ZipStream;      ZipEntry ZipEntry; String rtnmessage = "";//Returns the information of the try {//looping file, if the file does not exist on the compression not added inside for (int i = 0; i < ZipParameter.ZIPFileList.Count; i++) {if (!            File.exists (Zipparameter.zipfilelist[i])) {ZipParameter.ZIPFileList.RemoveAt (i);          i--; }        }//There is no file below the compression does not execute if (ZipParameter.ZIPFileList.Count = = 0) {return "File not find"        ; }//There is no directory to create if (! Directory.Exists (Zipparameter.zipdirectoryname)) {Directory.CreateDirectory (zipparameter.zipdirectoryname        );        }//solve the document name garbled problem, garbled is because codepage not Encoding GBK = encoding.getencoding ("GBK"); ICSharpCode.SharpZipLib.Zip.ZipConstants.DefaultCodePage = GBK.        CodePage;        File path, document path and file name string strpath = Zipparameter.zipdirectoryname + zipparameter.zipname;        Zip_file = File.create (strpath);        ZipStream = new Zipoutputstream (zip_file);          foreach (String filetozip in zipparameter.zipfilelist) {zip_file = File.openread (Filetozip);          byte[] buffer = new Byte[zip_file.length]; Zip_file.read (buffer, 0, buffer.)          Length);          Zip_file.close ();          ZipEntry = new ZipEntry (Path.getfilename (filetozip)); Zipstream.putnextentry(ZipEntry); Zipstream.write (buffer, 0, buffer.)        Length);        } zipstream.finish ();        Zipstream.close ();        Zip_file.close ();      Rtnmessage = "Success"; } catch (Exception ex) {rtnmessage = "fail:" + ex.      Message; } finally {GC.        Collect (); Gc.      Collect (1);    } return rtnmessage; }  }}


3. Using the class

Zipparameter ZP = new Zipparameter (); ZP. Zipdirectoryname = @ "C:\Users\Public\Pictures\Sample pictures\"; ZP. Zipname = "Test.zip"; ZP. Zipfilelist.add (@ "C:\Users\Public\Pictures\Sample pictures\chrysanthemum.jpg"); ZP. Zipfilelist.add (@ "C:\Users\Public\Pictures\Sample pictures\desert.jpg"); ZP. Zipfilelist.add (@ "C:\Users\Public\Pictures\Sample pictures\ error file. jpg"); Compressfile cprfile = new Compressfile (); cprfile.zipparameter = zp;string strmessage = cprfile.compressreturnmsg ();
