如何禁用Windows防火墙

Windows 7，8.1

当我尝试禁用Windows防火墙时，会出现异常。我试着用管理员权限来做这件事。但我对启用的Windows防火墙没有同样的问题。

Type NetFwMgrType = Type.GetTypeFromProgID("HNetCfg.FwMgr", false);
INetFwMgr mgr = (INetFwMgr)Activator.CreateInstance(NetFwMgrType);
// Get the Windows Firewall status
bool firewallEnabled = mgr.LocalPolicy.CurrentProfile.FirewallEnabled;
// it works fine...
String frw_status = "Windows Firewall is " + (firewallEnabled ?
    "enabled" : "disabled");
// Enable or disable firewall.
// I get the exception here when I try to disable Windows Firewall.
// I have not problem when I try to enable Windows Firewall (it works fine).
//
// Exception message:
//   An unhandled exception of type 'System.NotImplementedException' 
//   occurred in net_sandbox.exe
//   Additional information: Method or operation is not emplemented yet..
mgr.LocalPolicy.CurrentProfile.FirewallEnabled = false;

如何禁用Windows防火墙

您似乎使用的是Windows XP SP2 COM API，已知该应用程序在Windows Vista/7及更高版本上存在问题。

建议您使用更新的API：

（我还没有测试过这个）

Type netFwPolicy2Type = Type.GetTypeFromProgID("HNetCfg.FwPolicy2");
INetFwPolicy2 mgr = (INetFwPolicy2)Activator.CreateInstance(netFwPolicy2Type);
// Gets the current firewall profile (domain, public, private, etc.)
NET_FW_PROFILE_TYPE2_ fwCurrentProfileTypes = (NET_FW_PROFILE_TYPE2_)mgr.CurrentProfileTypes;
// Get current status
bool firewallEnabled = mgr.get_FirewallEnabled(fwCurrentProfileTypes);
string frw_status = "Windows Firewall is " + (firewallEnabled ?
"enabled" : "disabled");
// Disables Firewall
mgr.set_FirewallEnabled(fwCurrentProfileTypes, false);

private const string CLSID_FIREWALL_MANAGER =
  "{304CE942-6E39-40D8-943A-B913C40C9CD4}";
private static NetFwTypeLib.INetFwMgr GetFirewallManager()
{
    Type objectType = Type.GetTypeFromCLSID(
          new Guid(CLSID_FIREWALL_MANAGER));
    return Activator.CreateInstance(objectType)
          as NetFwTypeLib.INetFwMgr;
}
public static void Firewall()
{
    INetFwMgr manager = GetFirewallManager();
    bool isFirewallEnabled = manager.LocalPolicy.CurrentProfile.FirewallEnabled;
    manager.LocalPolicy.CurrentProfile.FirewallEnabled = false;
}

在Main.cs 中

yourclass.Firewall（）
