Windows 7, 8.1

尝试禁用 Windows防火墙时出现异常.我尝试使用管理员权限来执行此操作.但是对于Windows防火墙启用，我没有同样的问题.

I get an exception when I try to disable Windows Firewall. I try to do it with admin rights. But I haven't the same problem for Windows Firewall enabling.

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;

推荐答案

似乎您正在使用Windows XP SP2 COM API，该API在Windows Vista/7和更高版本上存在问题.

It seems you're using Windows XP SP2 COM API, which is known to have issues on Windows Vista/7 and newer versions.

建议您使用较新的API:

It's recommended that you use the newer API:

( 我还没有测试过 )

(I have not tested this)

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);
