  //生成解压目录
  Directory.CreateDirectory(directoryName);
    
  if (fileName != String.Empty)

  FileStream streamWriter = File.Create(args[1]+fileName);
    
  int size = 2048;
  byte[] data = new byte[2048];
  while (true)  
  {
  size = s.Read(data, 0, data.Length);
  if (size > 0)  
  {
  streamWriter.Write(data, 0, size);
  }  
  else  
  {
  break;
  }
  }
    
  streamWriter.Close();
  }
  }
  s.Close();
  }
  catch(Exception eu)
  {
  throw eu;
  }
  finally
  {
  s.Close();
  }

  }

以上代码报有异常：Wrong Local header signature: 0x90014
哪位大侠帮解决一下，困扰死我了！！谢谢咯！！！………………

原来使用过的，或用winrar,实现
public void UnZip(string[] args)
{
ZipInputStream s = new ZipInputStream(File.OpenRead(args[0]));

ZipEntry theEntry;
while ((theEntry = s.GetNextEntry()) != null)
{
string directoryName = Path.GetDirectoryName(args[1]);
string fileName = Path.GetFileName(theEntry.Name);
Directory.CreateDirectory(directoryName);
if (fileName != String.Empty)
{
//解压文件到指定的目录
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)
{
streamWriter.Write(data, 0, size);
}
else
{
break;
}
}
streamWriter.Close();
}
}
s.Close();
}
调用
string []FileProperties=new string[2];
FileProperties[0]=strPath; //待解压的文件
FileProperties[1]=strPhotoPath+@"\";//解压后放置的目标目录
UnZip(FileProperties);
