C # Under the use of ICSharpCode.SharpZipLib.dll to achieve file/folder compression and decompression

1, compress the log in a specified directory, compress the log into the Compressiondirectory folder, and clear the original uncompressed log.

#region compressed logs directory under log public static void Compresslogdic () {try {string logfilepath = Ap  
         PDomain.CurrentDomain.BaseDirectory + "Logs";  
         DirectoryInfo logsdic = new DirectoryInfo (LogFilePath);  
         fileinfo[] Biplog = Logsdic.getfiles ();  
         DateTime dt = DateTime.Now;  
         list<fileinfo> logsinoneday = new list<fileinfo> (); for (int i = 0; i < biplog.length i++) {if (biplog[i). Name.substring (Biplog[i].  
             name.length-3)!= "Zip") {Logsinoneday.add (biplog[i]);  
                 } if (Logsinoneday.count > 0) {try { if (! Directory.Exists (logsdic.fullname + "\\CompressionDirectory")) {Directory.creat  
                 edirectory (logsdic.fullname + "\\CompressionDirectory"); } String compressfilename = Dt.  
                 ToString ("Yyyy-mm-dd"); if (file.exists (Logsdic.fullname + "\\CompressionDirectory\\" + dt).  
                     ToString ("yyyy-mm-dd") + ". Zip")) {GUID guid = Guid.NewGuid (); Compressfilename = Compressfilename + "-" + GUID.  
                 ToString ();  
                 } compressfilename = ". zip";  
                 Compress (Logsinoneday, Logsdic.fullname + "\\CompressionDirectory\\" + compressfilename, 9, 100);  
                         foreach (FileInfo FileInfo in logsinoneday) {try {  
                     Fileinfo.delete ();  
                     catch (Exception e) {//Error information recording processing The catch (Exception e) {//  
     Error message record Processing}}}catch (Exception e) {//Error message log processing}} #endregion 

2, compress the log under the specified directory subdirectory, compress the log into the Compressiondirectory folder, and clear the original uncompressed log.

#region compressed logs log public static void Compresslogsdic () {try {string logfilepath = AppDomain.                 
        Currentdomain.basedirectory + "Logs";  
        DirectoryInfo logsdic = new DirectoryInfo (LogFilePath);  
        fileinfo[] Biplog = Logsdic.getfiles ();  
        DateTime dt = DateTime.Now;  
        directoryinfo[] Sublosgdic = Logsdic.getdirectories ();  
            foreach (DirectoryInfo bankdic in sublosgdic) {dt = DateTime.Now;  
            Biplog = Bankdic.getfiles ();  
            list<fileinfo> logsinoneday = new list<fileinfo> (); for (int i = 0; i < biplog.length i++) {if (biplog[i). Name.substring (Biplog[i].  
                name.length-3)!= "Zip") {Logsinoneday.add (biplog[i]);  
                 } if (Logsinoneday.count > 0) {try {   if (! Directory.Exists (bankdic.fullname + "\\CompressionDirectory")) {Directory .  
                    CreateDirectory (bankdic.fullname + "\\CompressionDirectory"); } string compressfilename = dt.  
                    ToString ("Yyyy-mm-dd"); if (file.exists (Bankdic.fullname + "\\CompressionDirectory\\" + dt).  
                        ToString ("yyyy-mm-dd") + ". Zip")) {GUID guid = Guid.NewGuid (); Compressfilename = Compressfilename + "-" + GUID.  
                    ToString ();  
				} compressfilename = ". zip"; This paper url:http://www.bianceng.cn/programming/csharp/201410/45594.htm Compress (Logsinoneday, bankdic.ful  
                    LName + "\\CompressionDirectory\\" + compressfilename, 9, 100);
                        foreach (FileInfo FileInfo in logsinoneday) {try  
      {                      Fileinfo.delete ();
