using ICSharpCode.SharpZipLib.Zip.Compression;
using ICSharpCode.SharpZipLib.Zip.Compression.Streams;
using ICSharpCode.SharpZipLib.GZip;string strPath = Server.MapPath("../Photo_tmp");
if(File1.PostedFile.FileName!="")
{
string mFileName=File1.PostedFile.FileName.Substring(File1.PostedFile.FileName.LastIndexOf("\\")+1);//取得文件名
strPath+=mFileName;
File1.PostedFile.SaveAs(strPath);
string []FileProperties=new string[2];
FileProperties[0]=strPath;
FileProperties[1]=strPhotoPath+@"\";
UnZip(FileProperties);
if(File.Exists(strPath))
File.Delete(strPath);
}
public void UnZip(string[] args)
{
ZipInputStream s = new ZipInputStream(File.OpenRead(args[0]));
  
ZipEntry theEntry = s.GetNextEntry();
while ((theEntry = s.GetNextEntry()) != null) 
{
   
string directoryName = Path.GetDirectoryName(args[1]);
string fileName      = Path.GetFileName(theEntry.Name);

   if (fileName != String.Empty) 
{   
                          FileStream streamWriter = File.Create(args[1]+theEntry.Name);
    
int size = 2048;
byte[] data = new byte[2048];
while (true) 
{
size = s.Read(data, 0, data.Length);
if (size > 0) 
{

else
