Question

I m在C#至zip文档中使用这一代码。我需要在安伯斯(java)开设这些档案:

String mp3Files = "E:\"; 
int TrimLength = mp3Files.ToString().Length;

byte[] obuffer;
string outPath = mp3Files + "\" + i + ".zip";
ZipOutputStream oZipStream = new ZipOutputStream(File.Create(outPath)); // create zip stream
oZipStream.SetLevel(9); // maximum compression

foreach (string Fil in ar) // for each file, generate a zipentry
{

    oZipEntry = new ZipEntry(Fil.Remove(0, TrimLength));
    oZipStream.PutNextEntry(oZipEntry);

    if (!Fil.EndsWith(@"/")) // if a file ends with  /  its a directory
    {
        ostream = File.OpenRead(Fil);
        obuffer = new byte[ostream.Length];
        ostream.Read(obuffer, 0, obuffer.Length);
        oZipStream.Write(obuffer, 0, obuffer.Length);
    }
}
oZipStream.Finish();
oZipStream.Close();

我在把这些档案摘录于java方面有问题,我希望确保问题从卷宗中解决。 j能够读一下这些zi子吗?

我只是试图通常使用赢利器制造,档案提取法也提出了同样的问题。

    String zipFile = Path + FileName;


            FileInputStream fin = new FileInputStream(zipFile);
            ZipInputStream zin = new ZipInputStream(fin);

            ZipEntry ze = null;
            while ((ze = zin.getNextEntry()) != null) {
                UnzipCounter++;
                if (ze.isDirectory()) {
                    dirChecker(ze.getName());
                } else {
                    FileOutputStream fout = new FileOutputStream(Path
                            + ze.getName());
                    while ((Unziplength = zin.read(Unzipbuffer)) > 0) {
                        fout.write(Unzipbuffer, 0, Unziplength);                    
                    }
                    zin.closeEntry();
                    fout.close();

                }

            }
            zin.close();

Answer 1

您的问题可能是由于文件文件InputStream的标式)指出,流必须可读。根据建议修改你的法典。在其网站上张贴部分守则:

using (var raw = File.Open(inputFileName, FileMode.Open, FileAccess.Read))
{
    using (var input= new ZipInputStream(raw))
    {
        ZipEntry e;
        while (( e = input.GetNextEntry()) != null)
        {

Answer 2

从我们在

FileInfo fi = new FileInfo(Fil); // added this line here
oZipEntry = new ZipEntry(Fil.Remove(0, TrimLength));
oZipEntry.Size = fi.Length;              // added this line here
oZipStream.PutNextEntry(oZipEntry);

如果 s合物不正确,则未经测试。
