Monotouch - ICSharpCode.SharpZipLib 用于解压缩文件

Question

我正在使用 ICSharpCode.SharpZipLib 解压一个包含文件、文件夹和子文件夹的文件，但我收到了一个错误，我在此处或任何其他论坛中都没有找到该错误。

代码：

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);

        }
}

错误得到：

有什么想法吗？

例如，您是否尝试过在 Windows 中通过 .NET 上的代码解压缩文件？也许该文件是通过 SharpZipLib 不支持的某种技术压缩的？

我的判断是，错误发生在“ICSharpCode.SharpZipLib.Zip.Compression.Inflater.Decode”方法中，如果您检查 SharpZipLib 的源代码，则该方法只会解码压缩字节数组。
