Hy家伙,
我正在尝试使用ICSharpCode.SharpZipLib库生成一个Zip文件,但它会引起一个非常奇怪的错误.
码：
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,obuffer.Length);
oZipStream.Write(obuffer,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
}
错误：
