Hy guys,
I'm trying to generate a Zip File with ICSharpCode.SharpZipLib library but it's throwing a really weird error.
Code:
public static void ZipFiles(string inputFolderPath, string outputPathAndFile, string password)
{
ArrayList ar = GenerateFileList(inputFolderPath); // generate file list
int TrimLength = (Directory.GetParent(inputFolderPath)).ToString().Length;
TrimLength += 1; //remove '\'
FileStream ostream;
byte[] obuffer;
ZipOutputStream oZipStream = new ZipOutputStream(File.Create(outputPathAndFile)); // create zip stream
if (password != null && password != String.Empty)
oZipStream.Password = password;
oZipStream.SetLevel(9); // maximum compression
ZipEntry oZipEntry;
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();
}
private static ArrayList GenerateFileList(string Dir)
{
ArrayList fils = new ArrayList();
bool Empty = true;
foreach (string file in Directory.GetFiles(Dir,"*.xml")) // add each file in directory
{
fils.Add(file);
Empty = false;
}
if (Empty)
{
if (Directory.GetDirectories(Dir).Length == 0)
// if directory is completely empty, add it
{
fils.Add(Dir + @"/");
}
}
foreach (string dirs in Directory.GetDirectories(Dir)) // recursive
{
foreach (object obj in GenerateFileList(dirs))
{
fils.Add(obj);
}
}
return fils; // return file list
}
Error:

How can I make this code support CodePage 437?

MonoTouch removes I18N codepages that it cannot statically determine that you need. You can force monotouch to keep the needed codepage collection (West) in this case one of two ways:
NOTE: You will need to perform step #3 for every combination of configurations and platforms.
