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;

//删除压缩前的文件
System.IO.File.Delete(fullName);
