DotNetZip组件写的方法，压缩成zip文件，打开zip文件里面的word文档会提示不应该显示的对话框

[zw520lbzw520lb]

我用这个组件写的压缩成zip文件，当打开zip，然后直接打开里面的word文档之类的，会提出如下的对话框，然后关闭word文档，又会弹出另外一个对话框。 之前是用ICSharpCode.SharpZipLib组件写的，同样的操作，不会弹出任何的对话框。





知道什么原因吗？ 不过如果全部解压出来之后再打开的话就没有问题的。

代码如下：

ICSharpCode.SharpZipLib版本的

public static string ZipFiles(string path, string zipFileName)
        {
            string fileName = string.Empty;

            try
            {
                // Depending on the directory this could be very large and would require more attention
                // in a commercial package.
                string[] filenames = Directory.GetFiles(path);
                fileName = Path.Combine(path, zipFileName + ".zip");

                // 'using' statements guarantee the stream is closed properly which is a big source
                // of problems otherwise.  Its exception safe as well which is great.
                using (ZipOutputStream s = new ZipOutputStream(File.Create(fileName)))
                {

                    s.UseZip64 = UseZip64.Off;

                    s.SetLevel(9); // 0 - store only to 9 - means best compression

                    byte[] buffer = new byte[4096];

                    foreach (string file in filenames)
                    {

                        // Using GetFileName makes the result compatible with XP
                        // as the resulting path is not absolute.
                        ZipEntry entry = new ZipEntry(Path.GetFileName(file));
                        entry.IsUnicodeText = true;

                        // Setup the entry data as required.

                        // Crc and size are handled by the library for seakable streams
                        // so no need to do them here.

                        // Could also use the last write time or similar for the file.
                        entry.DateTime = DateTime.Now;
                        s.PutNextEntry(entry);

                        using (FileStream fs = File.OpenRead(file))
                        {

                            // Using a fixed size buffer here makes no noticeable difference for output
                            // but keeps a lid on memory usage.
                            int sourceBytes;
                            do
                            {
                                sourceBytes = fs.Read(buffer, 0, buffer.Length);
                                s.Write(buffer, 0, sourceBytes);
                            } while (sourceBytes > 0);
                        }
                    }

                    // Finish is important to ensure trailing information for a Zip file is appended.  Without this
                    // the created file would be invalid.
                    s.Finish();
                }
            }
            catch (Exception)
            {
                // No need to rethrow the exception as for our purposes its handled.
            }

            return fileName;
        }

DotNetZip版本的

 public static string ZipFiles(string path, string zipFileName)
        {
            Logger.Debug(typeof(CompressionMgr), "ZipFiles");
            string fileName = string.Empty;
            try
            {
                // Depending on the directory this could be very large and would require more attention
                // in a commercial package.
                string[] fileNames = Directory.GetFiles(path);
                fileName = Path.Combine(path, zipFileName + ".zip");

                using (ZipFile zip = new ZipFile(Encoding.Default))
                {
                    foreach (string file in fileNames)
                    {
                        zip.AddFile(file, "");
                    }
                    zip.Save(fileName);
                }
            }
            catch (Exception)
            {
                // No need to rethrow the exception as for our purposes its handled.
            }

            return fileName;
        }

和用的解压库无关 因为你双击之后用word打开 关闭后可能修改了文件,rar检测到解压出来的临时文件被改动,会提示你是否把修改后的文件进行压缩,以更新压缩包

[threenewbee]

先释放到一个临时目录再打开，避免文件被锁定

问题是我打开就马上报这些消息了，没有任何改动文件。同样我自己的电脑上，效果就是不一样。

这样写就没问题了，看来还是和写法有关

public static string ZipFiles(string path, string zipFileName)
        {
            string fileName = string.Empty;

            try
            {
                // Depending on the directory this could be very large and would require more attention
                // in a commercial package.
                string[] filenames = Directory.GetFiles(path);
                fileName = Path.Combine(path, zipFileName + ".zip");

                // 'using' statements guarantee the stream is closed properly which is a big source
                // of problems otherwise.  Its exception safe as well which is great.
                using (ZipOutputStream s = new ZipOutputStream(File.Create(fileName)))
                {
                    s.AlternateEncoding = Encoding.UTF8;
                    s.AlternateEncodingUsage = ZipOption.AsNecessary;
                    s.EnableZip64 = Zip64Option.Never;
                    s.CompressionLevel = CompressionLevel.Level9; // 0 - store only to 9 - means best compression

                    byte[] buffer = new byte[4096];

                    foreach (string file in filenames)
                    {
                        // Using GetFileName makes the result compatible with XP
                        // as the resulting path is not absolute.                                   
                        s.PutNextEntry(Path.GetFileName(file));
                        using (FileStream fs = File.OpenRead(file))
                        {
                            // Using a fixed size buffer here makes no noticeable difference for output
                            // but keeps a lid on memory usage.
                            int sourceBytes;
                            do
                            {
                                sourceBytes = fs.Read(buffer, 0, buffer.Length);
                                s.Write(buffer, 0, sourceBytes);//write bytes
                            } while (sourceBytes > 0);
                        }
                    }
                }
            }
            catch (Exception)
            {                
            }

            return fileName;
        }
