我如何禁用Windows防火墙?

Windows 7,8.1

当我尝试禁用 Windows防火墙时出现exception。 我试图用pipe理员权限来做到这一点。 但是对于Windows防火墙的启用,我并没有同样的问题。

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;

看来你正在使用Windows XP SP2的COM API,这是已知的问题在Windows Vista / 7和更新的版本。

建议您使用较新的API:

我没有测试过这个

 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();
