Question

Mkay，所以我正在搞乱DotNetZip，我无法理解这一点。

基本上我将两个拉链合并在一起，之前覆盖了后者。为此，我使用以下代码从源zip中删除注入zip中的所有元素：

            foreach (ZipEntry entry in inZip)
            {
                if (outZip.ContainsEntry(entry.FileName))
                {
                    Log("Removing deprecated entry {0}", entry.FileName);
                    outZip.RemoveEntry(entry.FileName);
                }
            }

            outZip.Save();

然后我循环遍历注入zip中的所有元素，暂时将它们保存到文件中，然后在源zip中重新添加它们。像这样：

            foreach (ZipEntry entry in inZip)
            {
                if (!entry.IsDirectory)
                {
                    Log("Attempting to copy {0} to temp", entry.FileName);
                    string tempName = Path.Combine(tempPath, "tmp.tmp");
                    string oldName = entry.FileName;
                    byte[] buffer = new byte[65536];
                    Stream inStream = null;
                    FileStream stream = null;
                    try
                    {
                        Log("Reading from entry {0}", entry.FileName);
                        inStream = entry.OpenReader();
                        Log("Initializing new stream from path {0}", tempName);
                        stream = new FileStream(tempName, FileMode.Create, FileAccess.ReadWrite);
                        int size = 0;
                        Log("Prepping to read from stream");
                        while (
                            (size =
                            inStream.Read(buffer, 0, buffer.Length)) > 0)
                        {
                            Log("Reading {0} bytes from entry {1}", buffer.Length, entry.FileName);
                            stream.Write(buffer, 0, size);
                        }

                        Log("Closing and flushing streams");
                        inStream.Close();
                        stream.Flush();
                        stream.Close();
                        Log("Opening read stream");
                        inStream = new FileStream(tempName, FileMode.Open, FileAccess.Read);

                        Log("Adding new entry");
                        outZip.AddEntry(oldName, inStream);
                    }
                    catch (Exception exe)
                    {
                        throw exe;
                    }

它工作得很好，直到我开始点击最初删除的文件。然后我收到以下错误：

Ionic.Zlib.ZlibException: Bad state (invalid stored block lengths)

任何人都可以帮我弄清问题是什么吗？我把它缩小到了while循环。

                        while (
                            (size =
                            inStream.Read(buffer, 0, buffer.Length)) > 0)
                        {
                            Log("Reading {0} bytes from entry {1}", buffer.Length, entry.FileName);
                            stream.Write(buffer, 0, size);
                        }

DotNetZip会在特定文件中引发错误
