使用DotNetZip压缩与解压缩

下载地址：http://dotnetzip.codeplex.com/

 

解压后找到\\DotNetZipLib-DevKit-v1.9\zip-v1.9\Release下的Ionic.Zip.dll文件拷贝到C盘下

 

接着打开Visual Studio Command Prompt (2010),然后定位到C盘根目录，依次输入gacutil -i Ionic.Zip.dll 和regasm Ionic.Zip.dll ，然后拷贝C盘下的这个Ionic.Zip.dll到您的应用程序中，添加引用即可！代码例子如下：

具体的例子：

//获取压缩包路径

            string filename = material.CreationTime.ToyyyyMMdd().Replace("-", "");



            //string zippath = AppDomain.CurrentDomain.BaseDirectory + "upload\\Zipped\\" + filename;

            //和上面的结果一样

            string zippath = material.FilePath;

            string decomPath = "";

            string nowpath = "";

            if (material.FilePath.Substring(material.FilePath.Length - 3, 3).Equals("zip"))

            { decomPath = material.FilePath.Replace(".zip", ""); }

            if (material.FilePath.Substring(material.FilePath.Length - 3, 3).Equals("rar"))

            { decomPath = material.FilePath.Replace(".rar", ""); }

            //查询此目录下是否存在需要解压过的同名的文件夹名称
