什么是 ICSharpCode.SharpZipLib.ZipEntry.Flag？

Question

有人可以举个例子吗，我用谷歌搜索但没有找到任何合适的结果。

我想给出标志，以便在文件名带有特殊字符的情况下使用原始名称压缩文件。

例如，目前我正在使用

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

什么标志来支持特殊字符文件名？

谢谢

此组件的源代码可在此处获取：

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，像您所做的那样，将 2048 与 Flags 进行“或”运算看起来是正确的。或者，您可以设置 IsUnicodeText 属性，该属性执行相同的操作，但使代码看起来更简洁：

entry.IsUnicodeText = true;
