モノトゥッチ - 解凍ファイルのICSharpCode.SharpZipLib

Question

ICSharpCode.SharpZipLibを使用して、ファイル、フォルダ、サブフォルダが入っているファイルを解凍しますが、私はここや他のフォーラムで見つけられなかったエラーを受け取ります。

コード：

public static void UnZipFiles(string zipPathAndFile, string outputFolder, string password, bool deleteZipFile) 
{ 
     ZipInputStream s = new ZipInputStream(File.OpenRead(zipPathAndFile)); 
     if (password != null && password != String.Empty) 
      s.Password = password; 
     ZipEntry theEntry; 
     string tmpEntry = String.Empty; 
     while ((theEntry = s.GetNextEntry()) != null) 
     { 
      string directoryName = outputFolder; 
      string fileName = Path.GetFileName(theEntry.Name); 
      // create directory 
      if (directoryName != "") 
      { 
       Directory.CreateDirectory(directoryName); 
      } 
      if (fileName != String.Empty) 
      { 
       if (theEntry.Name.IndexOf(".ini") < 0) 
       { 
        string fullPath = directoryName + "\\" + theEntry.Name; 
        fullPath = fullPath.Replace("\\ ", "\\"); 
        string fullDirPath = Path.GetDirectoryName(fullPath); 
        if (!Directory.Exists(fullDirPath)) Directory.CreateDirectory(fullDirPath); 
        FileStream streamWriter = File.Create(fullPath); 
        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(); 
     if (deleteZipFile) 
     { 
      File.Delete(zipPathAndFile); 

     } 
}

任意のアイデア？

Answer 1

あなたはたとえば、Windowsで.NETのコードを経由してファイルを解凍しようとしたことがありますか？ sharpZipLibがサポートしていないいくつかのテクニックでファイルが圧縮されている可能性がありますか？

「ICSharpCode.SharpZipLib.Zip.Compression.Inflater.Decode」メソッドでエラーが発生すると判断しました.SharpZipLibのソースコードをチェックすると、収縮したバイトの配列がデコードされます。
