一、 添加 COM 引用

在引用里，选择 COM 页， 找到 NetFwTypeLib, 确定即可

二、 添加允许通过防火墙的例外程序

using System;

using System.Collections.Generic;

using System.Linq;

using System.Text;

using NetFwTypeLib;

namespace Common

{

public static class INetFwManger

{

///

/// 添加防火墙例外端口

///

/// 名称

/// 端口

/// 协议(TCP、UDP)

public static void NetFwAddPorts(string name, int port, string protocol)

{

//创建firewall管理类的实例

INetFwMgr netFwMgr = (INetFwMgr)Activator.CreateInstance(Type.GetTypeFromProgID("HNetCfg.FwMgr"));

INetFwOpenPort objPort = (INetFwOpenPort)Activator.CreateInstance(

Type.GetTypeFromProgID("HNetCfg.FwOpenPort"));

objPort.Name = name;

objPort.Port = port;

if (protocol.ToUpper() == "TCP")

{

objPort.Protocol = NET_FW_IP_PROTOCOL_.NET_FW_IP_PROTOCOL_TCP;

}

else

{

objPort.Protocol = NET_FW_IP_PROTOCOL_.NET_FW_IP_PROTOCOL_UDP;

}

objPort.Scope = NET_FW_SCOPE_.NET_FW_SCOPE_ALL;

objPort.Enabled = true;

bool exist = false;

//加入到防火墙的管理策略

foreach (INetFwOpenPort mPort in netFwMgr.LocalPolicy.CurrentProfile.GloballyOpenPorts)

{

if (objPort == mPort)

{

exist = true;

break;

}

}

if (!exist) netFwMgr.LocalPolicy.CurrentProfile.GloballyOpenPorts.Add(objPort);

}

///

/// 将应用程序添加到防火墙例外

///

/// 应用程序名称

/// 应用程序可执行文件全路径

public static void NetFwAddApps(string name, string executablePath)

{

//创建firewall管理类的实例

INetFwMgr netFwMgr = (INetFwMgr)Activator.CreateInstance(Type.GetTypeFromProgID("HNetCfg.FwMgr"));

INetFwAuthorizedApplication app = (INetFwAuthorizedApplication)Activator.CreateInstance(

Type.GetTypeFromProgID("HNetCfg.FwAuthorizedApplication"));

//在例外列表里，程序显示的名称

app.Name = name;

//程序的路径及文件名

app.ProcessImageFileName = executablePath;

//是否启用该规则

app.Enabled = true;

//加入到防火墙的管理策略

netFwMgr.LocalPolicy.CurrentProfile.AuthorizedApplications.Add(app);

bool exist = false;

//加入到防火墙的管理策略

foreach (INetFwAuthorizedApplication mApp in netFwMgr.LocalPolicy.CurrentProfile.AuthorizedApplications)

{

if (app == mApp)

{

exist = true;

break;

}

}

if (!exist) netFwMgr.LocalPolicy.CurrentProfile.AuthorizedApplications.Add(app);

}

///

/// 删除防火墙例外端口

///

/// 端口

/// 协议(TCP、UDP)

public static void NetFwDelApps(int port,string protocol)

{

INetFwMgr netFwMgr = (INetFwMgr)Activator.CreateInstance(Type.GetTypeFromProgID("HNetCfg.FwMgr"));

if (protocol == "TCP")

{

netFwMgr.LocalPolicy.CurrentProfile.GloballyOpenPorts.Remove(port, NET_FW_IP_PROTOCOL_.NET_FW_IP_PROTOCOL_TCP);

}

else

{

netFwMgr.LocalPolicy.CurrentProfile.GloballyOpenPorts.Remove(port, NET_FW_IP_PROTOCOL_.NET_FW_IP_PROTOCOL_UDP);

}

}

///

/// 删除防火墙例外中应用程序

///

/// 程序的绝对路径

public static void NetFwDelApps(string executablePath)

{

INetFwMgr netFwMgr = (INetFwMgr)Activator.CreateInstance(Type.GetTypeFromProgID("HNetCfg.FwMgr"));

netFwMgr.LocalPolicy.CurrentProfile.AuthorizedApplications.Remove(executablePath);

}

}

}
