1.建立工程，添加引用，添加SharpZipLib.dll

2.建立压缩和解压类CompressionFile.cs

添加如下代码

using System;

using System.IO;

using ICSharpCode.SharpZipLib.Zip;

using ICSharpCode.SharpZipLib.GZip;

using ICSharpCode.SharpZipLib.BZip2;

using ICSharpCode.SharpZipLib.Checksums;

using ICSharpCode.SharpZipLib.Zip.Compression;

using ICSharpCode.SharpZipLib.Zip.Compression.Streams;
