c# - 异常: EOF in Header occuring while extracting zip from isolated storage

Question

我使用流编写器在名为 temp.zip 的独立存储中生成了一个 zip，并在流中返回其字节以进行提取。请找到以下代码

stream = LoadZipFromLocalFolder(filename);
using (IsolatedStorageFile isoStore = IsolatedStorageFile.GetUserStoreForApplication())
{
    using (var zipStream = new ZipInputStream(stream))
    {
        ZipEntry entry;
        //EOF in header occuring on below line
        while ((entry = zipStream.GetNextEntry()) != null)
        {
            string directoryName = Path.GetDirectoryName(entry.Name);
            string fileName = Path.GetFileName(entry.Name);

            if (!string.IsNullOrEmpty(fileName))
            {
                if (!isoStore.DirectoryExists(directoryName))
                {
                    isoStore.CreateDirectory(directoryName);
                }

                string fileFullPath = Path.Combine(directoryName, fileName);
                Debug.WriteLine(fileFullPath);
                using (var streamWriter = new BinaryWriter(new IsolatedStorageFileStream(fileFullPath, FileMode.Create, FileAccess.Write, FileShare.Write, isoStore)))
                {
                    var buffer = new byte[2048];
                    int size;
                    while ((size = zipStream.Read(buffer, 0, buffer.Length)) > 0)
                    {
                        streamWriter.Write(buffer, 0, size);
                    }
                    streamWriter.Close();
                    streamWriter.Dispose();
                }
            }
        }
    }
}

当我创建 temp.zip 时，它具有读写、共享权限，并且我尝试手动解压缩，然后它被正确提取而不会导致任何错误，但在代码显示错误 HEADER 中的 EOF。

请帮忙..

谢谢

Answer 1

我通过使用简单的代码解决了 header 中的EOF，如下所示:

Stream.Position =0;

希望它对某人有所帮助。

谢谢。
