在适用于Windows 7和Xp Sp3的C#中控制Windows防火墙
我这里有一个在Windows7中运行完美的代码,我从post获得了帮助 当相同的代码在WinXP Sp3 PC上编译时,问题就来了。它不好笑。。。表示接口丢失(错误) 我似乎不明白。我再次为windows xp添加了对hnetcfg.dll(COM APi引用)的引用(在windows 7中,我必须为project添加另一个dll“FirewallAPi.dll”)在适用于Windows 7和Xp Sp3的C#中控制Windows防火墙,c#,wpf,windows-7-x64,windows-xp-sp3,windows-firewall-api,C#,Wpf,Windows 7 X64,Windows Xp Sp3,Windows Firewall Api,我这里有一个在Windows7中运行完美的代码,我从post获得了帮助 当相同的代码在WinXP Sp3 PC上编译时,问题就来了。它不好笑。。。表示接口丢失(错误) 我似乎不明白。我再次为windows xp添加了对hnetcfg.dll(COM APi引用)的引用(在windows 7中,我必须为project添加另一个dll“FirewallAPi.dll”) using NATUPNPLib; using NETCONLib; using NetFwTypeLib; 但是接口和其他类对

如何使FirewallManager与两个操作系统版本兼容,或者以其他方式(如果可能)兼容
感谢您的帮助……MSDN文章的备注部分明确提到: Windows Vista:Windows Vista用户必须将在Windows Vista中开发的应用程序用于此界面的所有方法和属性 这是一种说INetFwMgr接口实现在Vista中被替换的有点蹩脚的说法。它有一个新的IID,所以如果你在运行Vista或更高版本的机器上构建你的程序,那么你的程序将在XP上崩溃。您需要为XP用户创建一个特殊的程序版本。您需要使用嵌入在XP版本c:\windows\system32\firewallapi.dll中的类型库来完成此操作。通过在该DLL上运行tlbimp.exe获取互操作库。拥有一台引导XP的机器或虚拟机当然是获取DLL副本和测试构建的好方法
