Is The Code I'm Using To Make .zip Files Correct?

I'm using this code in C# to zip files.. I need to open these files in an Android app (java): String mp3Files = 'E:\\'; int TrimLength = mp3Files.ToString().Length; byte[] obuffe

Solution 1:

Your problem might be due to FileInputStream object's mode. This link (has C# code) states the stream must be readable. Try changing your code according to their recommendation. Posting part of the code from their site:

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

Solution 2:

From the dicussion we've had on this question, the size of your entry is being set to 4294967295, which is the reason you're having a problem with the unzip in java. Try setting the Size:

FileInfofi=newFileInfo(Fil); // added this line here
oZipEntry = newZipEntry(Fil.Remove(0, TrimLength));
oZipEntry.Size = fi.Length;              // added this line here
oZipStream.PutNextEntry(oZipEntry);

Apologies if the syntax is incorrect, this is untested.
