自动化 Windows 防火墙 [英] Automating Windows Firewall with
本文介绍了自动化 Windows 防火墙的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！
问题描述
我有 C# 应用程序，它使用 PORT 777 进行异步通信，使用 PORT 3306 与 My Sql Server 进行通信.当端口被防火墙阻止时，就会出现问题.我尝试创建一个程序，在 Windows 7 的防火墙列表中添加例外.
当我运行程序时，出现如下错误: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.

在使用以下程序之前，请在 Visual Studio 2010 中添加参考 FirewallAPI.dll.请执行下列操作:从 Visual Studio 2010 的 Solution Explorer 右键单击项目 - 选择 Add Reference - 选择 C:WindowsSystem32FirewallAPI.dll - 好的
使用下面的 3 行代码调用程序防火墙.您可以将此代码放入程序的表单加载中:
<块引用>private clsFirewall objFirewall = new clsFirewall();objFirewall.CloseFirewall();objFirewall.OpenFirewall();

Problems arise when the ports is blocked by a firewall. I tried to create a program to add an exception in the firewall list of Windows 7.
When i run the program, i get bug as follow: "Catastrophic failure (Exception from HRESULT: 0x8000FFFF (E_UNEXPECTED))".
I do not understand what these errors mean, any suggestion is welcome, Thanks.
