什么是ICSharpCode.SharpZipLib.ZipEntry.Flag？

Question

有没有人能举个例子，我用谷歌搜索了一下，但没有找到合适的结果。

我想给出一个标志，这样在文件名的情况下，它就会用它的原始名称压缩文件

对于特殊的characters.for示例，我目前正在使用

ZipEntry entry = new ZipEntry(file.FullName.Substring(directory.FullName.Length + 1));
                    entry.Flags |= 2048; // enable UTF8 file names

支持特殊字符文件名的标志应该是什么？

谢谢

此处提供了此组件的源代码：

如果您下载源代码并查看ZipEntry的代码，您将发现Flags属性的以下注释。

///
/// Get/Set general purpose bit flag for entry
///
///
/// General purpose bit flag
///
/// Bit 0: If set, indicates the file is encrypted
/// Bit 1-2 Only used for compression type 6 Imploding, and 8, 9 deflating
/// Imploding:
/// Bit 1 if set indicates an 8K sliding dictionary was used.  If clear a 4k dictionary was used
/// Bit 2 if set indicates 3 Shannon-Fanno trees were used to encode the sliding dictionary, 2 otherwise
///
/// Deflating:
///   Bit 2    Bit 1
///     0        0       Normal compression was used
///     0        1       Maximum compression was used
///     1        0       Fast compression was used
///     1        1       Super fast compression was used
///
/// Bit 3: If set, the fields crc-32, compressed size
/// and uncompressed size are were not able to be written during zip file creation
/// The correct values are held in a data descriptor immediately following the compressed data.
/// Bit 4: Reserved for use by PKZIP for enhanced deflating
/// Bit 5: If set indicates the file contains compressed patch data
/// Bit 6: If set indicates strong encryption was used.
/// Bit 7-10: Unused or reserved
/// Bit 11: If set the name and comments for this entry are in <a href="http://www.unicode.org">unicode</a>.
/// Bit 12-15: Unused or reserved
///
/// <seealso cref="IsUnicodeText"></seealso>
/// <seealso cref="IsCrypted"></seealso>

因此，您所做的ORing 2048 into Flags看起来是正确的。或者，您可以设置IsUnicodeText属性，该属性做同样的事情，但会使代码看起来更干净一些：

entry.IsUnicodeText = true;
