asp.net用代碼壓縮服務器上文件夾或文件

　　實現過程

）先引用 ICSharpCodeSharpZipLibdll

）cs文件引入

using SystemIO;
using SystemText;

using ICSharpCodeSharpZipLibChecksums;
using ICSharpCodeSharpZipLibZip;
using ICSharpCodeSharpZipLibGZip;  

）代碼 

 #region 下列代碼為壓縮並下載代碼
       ZipOutputStream zos = null;
       String strBaseDir = ""; 

       void dlZipDir(string strPath string strFileName)
       {

           zos = new ZipOutputStream(ms);
           strBaseDir = strPath + "";
           addZipEntry(strBaseDir);
           zosFinish();
           zosClose();
           ResponseClear();
           ResponseBinaryWrite(msToArray());
           ResponseEnd();
       }

       void addZipEntry(string PathStr)
       {

           foreach (DirectoryInfo item in diGetDirectories())

           }
           foreach (FileInfo item in diGetFiles())
           {

               byte[] buffer = new byte[fsLength];
               fsRead(buffer  bufferLength);
               string strEntryName = itemFullNameReplace(strBaseDir "");
               ZipEntry entry = new ZipEntry(strEntryName);
               zosPutNextEntry(entry);
               zosWrite(buffer  bufferLength);
               fsClose();
           }
       }    
        
       PRotected void Button_Click(object sender EventArgs e)
        {
            string userPath ="D:華海實訓（hohisoftcom）各級賬號和密碼";
