}

using System;

4：使用

            ZipParameter zp = new ZipParameter();
            zp.Password = "";
            zp.Level = ;
            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\WH130406P\Documents\RelatedTemplate.xlsx");

            DeZipParameter dzp = new DeZipParameter();
            dzp.ZIPFullPath = @"D:\项目必备\开发实例\wf20131124.zip";
            dzp.ZIPDirectoryName = @"C:\Users\Public\Pictures\Sample Pictures\Test";
            dzp.Password = "";

            ZipFolderParameter zfp = new ZipFolderParameter();
            zfp.ZipFileName = @"C:\Users\Public\Pictures\Sample Pictures\zipFolder.zip";
            zfp.SourceDirectory = @"D:\xs\項目";
            zfp.Recurse = true;

            CompressFile cprFile = new CompressFile();
            cprFile.ZipParameter = zp;
            cprFile.DeZipParameter = dzp;
            cprFile.ZipFolderParameter = zfp;
            cprFile.Compress();
            cprFile.Decompress();
            cprFile.CompressFolder();

上面都是我使用的过程，都是实践成功了的
