使用自动化Windows防火墙

篇首语:本文由小常识网(cha138.com)小编为大家整理,主要介绍了使用自动化Windows防火墙相关的知识,希望对你有一定的参考价值。
我有C#应用程序使用PORT 777进行异步通信,PORT 3306用于与My Sql Server进行通信。端口被防火墙阻止时出现问题。我试图创建一个程序,在Windows 7的防火墙列表中添加一个例外。
当我运行程序时,我得到如下错误:“灾难性故障(HRESULT异常:0x8000FFFF(E_UNEXPECTED))”。
我不明白这些错误是什么意思,欢迎提出任何建议,谢谢。

- 在使用下面的程序之前,请将参考FirewallAPI.dll添加到Visual Studio 2010.执行以下操作:在Visual Studio 2010的解决方案资源管理器中右键单击项目 - 选择添加引用 - 选择C: Windows System32 FirewallAPI。 dll - 好的
- 使用以下3行代码调用程序防火墙。您可以将此代码放在程序的表单加载中:
private clsFirewall objFirewall = new clsFirewall(); objFirewall.CloseFirewall(); objFirewall.OpenFirewall();

另一答案
Javanese Girl接受的答案具有类似C的实现,具有无声明使用模式和冗余代码。这是基于该答案的重构实现。它使用所有相同的调用FirewallAPI.dll;它在功能上是等价的,因此它解决了原始问题无法使这些类型的防火
