在Vista中编程控制防火墙设定
来源:Http://myeducs.cn 联系QQ:点击这里给我发消息 作者: 佚名 来源: 网络 发布时间: 10/11/03

  在编程控制防火墙前先要有个前提,就是你必须是管理员权限, 这样本例的程序才能用"Run as administrator"的方式运行,并成功修改。 如果你本身就是用Administrator这个用户登录的话,直接运行就行了。 建议最好在这个用户下来调试程序

  本程序只是个初始的例子,里面的功能只开发了一部分,各位有兴趣的话可以继续深入运用。 像Vista的防火墙就比较Bt,除了基本设定外,在"Control Panel\Administrative Tools\Windows Firewall with Advanced Security" 还有高级设定,好像用程序都可控制。

  FireWallManager 程序主要功能有

  1. public void FireWallTrigger( bool enable ) //开关防火墙。 貌似在Vista里面有问题,XP sp2好像可以。 但是用INetFwPolicy2.set_FirewallEnabled的方法的话,Vista也能搞定。

  2. public void FireWallService( string name, bool enable ) //开关防火墙服务程序,一般里面的 File and Printer Sharing 服务比较有用。

  3. public bool AddPort( string portName, int portNumber, string protocol ) // 开启一个端口。

  4. public bool RemovePort( int portNumber, string protocol ) //删除开启的端口

  5. public bool AddAplication( string discriptionName, string fileName ) //开启放行应用程序

  6. public bool RemoveApplication( string fileName ) // 关闭放行的应用程序

  里面还有个 protected Object getInstance( String typeName ) 本来是用CLSID来实例化那些接口的,后来发现ProgID其实更简单,不需要查,里面有个规律,只需把接口的INet删掉就是ProgID了。 如 INetFwOpenPort port = ( INetFwOpenPort )Activator.CreateInstance( Type.GetTypeFromProgID( "HNetCfg.FwOpenPort" ) ); 中 INetFwOpenPort 与 FwOpenPort.

  首先,创建一个Console程序,在程序中添加引用,在COM对象中找到"NetFwTypeLib" ,添加即可。 防火墙主要是靠这个对象操作的。 貌似不止Vista, Xp也是一样的。核心程序如下:

 FireWallManager.cs
using System;

using NetFwTypeLib;
namespace FirewallManager
{
class FwManager
{
private INetFwMgr NetFwMgr;
private INetFwProfile NetFwProfile;
private INetFwPolicy2 NetFwPolicy2; //this interface contains lots of usefull functions.
public FwManager()
{
//Create Com Object
//Type NetFwMgrType = Type.GetTypeFromCLSID( new Guid( "{304CE942-6E39-40D8-943A-B913C40C9CD4}" ) );
Type NetFwMgrType = Type.GetTypeFromProgID( "HNetCfg.FwMgr" );
object NetFwMgrObject = Activator.CreateIn
stance( NetFwMgrType );
NetFwMgr = ( INetFwMgr )NetFwMgrObject;
NetFwProfile = NetFwMgr.LocalPolicy.CurrentProfile;
Type NetFwPolicy2Type = Type.GetTypeFromProgID( "HNetCfg.FwPolicy2" );
object NetFwPolicy2Object = System.Activator.CreateInstance( NetFwPolicy2Type );
NetFwPolicy2 = ( INetFwPolicy2 )NetFwPolicy2Object;
}
public void ShowInfo()
