本文所述为一个C#使用iCSharpcode压缩的使用类，经测试效果不错。分享给大家供大家参考之用。具体方法如下：

1.参数类

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> /// 压缩后的文件名称 /// </summary> public string ZIPName { get { return zip_Name; } set { zip_Name = value; } } /// <summary> /// 压缩的文件路径 /// </summary> public string ZIPDirectoryName { get { return zip_DirectoryName; } set { zip_DirectoryName = value; } } /// <summary> /// 压缩的文件列表 /// </summary> public List<string> ZIPFileList { get { return zip_FileList; } set { zip_FileList = value; } } } }

2.工作类

//**************************************************************************************** //功能：实现文件压缩 //使用方法：设置参数进行压缩 //***************************************************************************************** using System; using ICSharpCode.SharpZipLib.Zip; using System.IO; using System.Text; namespace ZipCompress { public class CompressFile { /// <summary> /// 压缩文件参数 /// </summary> public ZipParameter ZipParameter { get; set; } /// <summary> /// 压缩文件返回压缩后的信息 /// </summary> /// <returns>string 返回压缩后的提示信息</returns> public string CompressReturnMsg() { FileStream Zip_File; ZipOutputStream ZipStream; ZipEntry ZipEntry; string rtnMessage = "";//返回的信息 try { //循环文件，如果文件不存在就不添加的压缩里面 for (int i = 0; i < ZipParameter.ZIPFileList.Count; i++) { if (!File.Exists(ZipParameter.ZIPFileList[i])) { ZipParameter.ZIPFileList.RemoveAt(i); i--; } } //没有有文件下面的压缩不执行 if (ZipParameter.ZIPFileList.Count == 0) { return " file not find"; } //没有目录进行创建 if (!Directory.Exists(ZipParameter.ZIPDirectoryName)) { Directory.CreateDirectory(ZipParameter.ZIPDirectoryName); } // 解决文档名称乱码问题,出现乱码就是因为CodePage不对 Encoding gbk = Encoding.GetEncoding("gbk"); ICSharpCode.SharpZipLib.Zip.ZipConstants.DefaultCodePage = gbk.CodePage; //文件路径，文档路径与文件名称 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.使用类

ZipParameter zp = new ZipParameter(); zp.ZIPDirectoryName = @"C:UsersPublicPicturesSample Pictures"; zp.ZIPName = "Test.zip"; zp.ZIPFileList.Add(@"C:UsersPublicPicturesSample PicturesChrysanthemum.jpg"); zp.ZIPFileList.Add(@"C:UsersPublicPicturesSample PicturesDesert.jpg"); zp.ZIPFileList.Add(@"C:UsersPublicPicturesSample Pictures错误文件.jpg"); CompressFile cprFile = new CompressFile(); cprFile.ZipParameter = zp; string strMessage = cprFile.CompressReturnMsg();
