SVN即时邮寄

Question

我在我的Windows 2003服务器上安装了VisualSVN,并将其配置为提供匿名读访问.根据我的理解,VisualSVN只使用apache和下面的官方SVN Repository服务器.

现在,我想扩展SVN网页以提供"下载HEAD as ZIP"功能.像SourceForge和Codeplex这样的Web门户确实提供了这种功能.

是否有SVN Repository服务器的插件？或者可能是一个单独的Web客户端(最好是ASP.NET)？

我找到了一个解决方案,并希望与您分享,以防其他人想要实现相同的解决方案.

在分析了WebSvn之后,我发现他们使用SVN导出目录功能将源代码下载到本地文件夹,然后即时压缩目录.表现相当不错.

我在C#中的解决方案是使用SharpSVN和DotNetZip.完整的源代码可以在我的SVN存储库中找到.
