       toggleButton1.Background = Brushes.LawnGreen;
       INetFwMgr mgr = (INetFwMgr)Activator.CreateInstance(NetFwMgrType);
       mgr.LocalPolicy.CurrentProfile.FirewallEnabled = true;
   }

   private void toggleButton1_Unchecked(object sender, RoutedEventArgs e)
   {
       toggleButton1.Content = "Off";
       toggleButton1.Background = Brushes.Red;

       mgr.LocalPolicy.CurrentProfile.FirewallEnabled=false;
   }

首先我认为你只会要求提升。我很快写了一个应用来测试这个理论。

以普通用户身份运行应用程序，我得到了同样的错误。然后我以管理员身份重新启动了IDE并再次尝试。这次我收到错误尚未实施。这是使用.Net4 .....

为什么微软说尚未实现是超出我的。



问题是，为什么你需要禁用防火墙，因为这首先会破坏防火墙的目的。但是你可以在防火墙上添加一个例外。



这是我使用的一段代码：

First I thought that you would only require elevation. I quickly wrote an application to test this theory.
Running the application as normal user, I got the same error. I then restarted my IDE as an administrator and tried again. This time I got the error "Not Yet Implemented". This was using .Net4.....
Why Microsoft says not yet implemented is beyond me.

Question is, why do you need to disable the firewall as this defeats the purpose of the firewall in the first place. You can however add an exception to the firewall.

Here is a piece of my code that I use:

public void OpenPort(string Name, int Port, NET_FW_IP_PROTOCOL_ protocol)
{
       INetFwMgr fwMgr = (INetFwMgr)getInstance("INetFwMgr");
       INetFwPolicy fwPolicy = fwMgr.LocalPolicy;
       INetFwProfile fwProfile = fwPolicy.CurrentProfile;
       INetFwOpenPorts openports = fwProfile.GloballyOpenPorts;
       INetFwOpenPort openport = (INetFwOpenPort)getInstance("INetOpenPort");
       openport.Port = Port;
       //.Protocol = NET_FW_IP_PROTOCOL_.NET_FW_IP_PROTOCOL_UDP
       openport.Protocol = protocol;
       openport.Name = Name + Port; //The description that will be displayed in windows firewall.
       openports.Add(openport);
       fwMgr = null;
       fwPolicy = null;
       fwProfile = null;
       openports = null;
       openport = null;
   }

您应该使用Policy2互操作而不是防火墙管理器互操作。这将允许您将防火墙设置为启用等于false。

You should be using the Policy2 interop instead of the Firewall Manager interop. That will allow you to set the firewall to enabled equal false.
