写一个程序，需要关闭防火墙，系统是win10，现在把过程分享一下，有需要的朋友可以看一下。

首先引用 NetFwTypeLib 和 System.ServiceProcess

操作防火墙的函数和使用方法代码如下：

using Microsoft.Win32;using NetFwTypeLib;using System;using System.Diagnostics;using System.IO;using System.ServiceProcess;using System.Windows.Forms;namespace WindowsFormsApplication1{ public partial class Form1 : Form { public Form1() { InitializeComponent(); } FIREWALL fw = new FIREWALL(); private void button1_Click(object sender, EventArgs e) { fw.打开防火墙(); } private void button2_Click(object sender, EventArgs e) { fw.关闭防火墙(); } //操作防火墙的类,还是一样,懒的话照抄就行 public class FIREWALL { public void 打开防火墙() { //看看系统是不是WIN10 RegistryKey rk = Registry.LocalMachine.OpenSubKey(@"Software\\Microsoft\\Windows NT\\CurrentVersion"); var SystemTip = rk.GetValue("ProductName").ToString(); rk.Close(); if (!SystemTip.StartsWith("Windows 10")) { MessageBox.Show("不是win10系统！"); return; } //防火墙服务名称 string ServicerName = "MpsSvc"; RegistryKey key = Registry.LocalMachine.OpenSubKey(@"SYSTEM\\CurrentControlSet\\Services\\" + ServicerName, true); //如果防火墙启动类型是禁止,更改其为自动 var StartIndex = key.GetValue("Start").ToString(); Log("StartIndex:" + StartIndex.ToString()); if (StartIndex == "4") { try { ProcessStartInfo objProInfo = new ProcessStartInfo(); objProInfo.FileName = "cmd.exe"; objProInfo.CreateNoWindow = false; objProInfo.WindowStyle = ProcessWindowStyle.Hidden; objProInfo.Arguments = "/c sc config " + ServicerName + " start= " + "auto"; Process.Start(objProInfo); //等待操作执行完毕 System.Threading.Thread.Sleep(1000); } catch (Exception ex) { Log("防火墙启动类型设置失败,原因：\r\n" + ex.ToString()); return; } } key.Close(); // 确保防火墙服务是启动状态 ServiceController sc = new ServiceController(ServicerName); if ((sc.Status.Equals(ServiceControllerStatus.Stopped)) || (sc.Status.Equals(ServiceControllerStatus.StopPending))) { sc.Start(); Log("防火墙服务已经开启。"); //等待操作执行完毕 System.Threading.Thread.Sleep(1000); } //开始打开防火墙 try { INetFwPolicy2 FP = (INetFwPolicy2)Activator.CreateInstance(Type.GetTypeFromProgID("HNetCfg.FwPolicy2")); // 启用公用防火墙 FP.set_FirewallEnabled(NET_FW_PROFILE_TYPE2_.NET_FW_PROFILE2_PUBLIC, true); // 启用专用防火墙 FP.set_FirewallEnabled(NET_FW_PROFILE_TYPE2_.NET_FW_PROFILE2_PRIVATE, true); Log("防火墙已相打开"); } catch(Exception ex) { Log("开启防火墙失败,原因：\r\n" + ex.ToString()); return; } } public void 关闭防火墙() { //看看系统是不是WIN10 RegistryKey rk = Registry.LocalMachine.OpenSubKey(@"Software\\Microsoft\\Windows NT\\CurrentVersion"); var SystemTip = rk.GetValue("ProductName").ToString(); rk.Close(); if (!SystemTip.StartsWith("Windows 10")) { MessageBox.Show("不是win10系统！"); return; } //关闭防火墙 try { INetFwPolicy2 FP = (INetFwPolicy2)Activator.CreateInstance(Type.GetTypeFromProgID("HNetCfg.FwPolicy2")); // 禁用公用防火墙 FP.set_FirewallEnabled(NET_FW_PROFILE_TYPE2_.NET_FW_PROFILE2_PUBLIC, false); // 禁用专用防火墙 FP.set_FirewallEnabled(NET_FW_PROFILE_TYPE2_.NET_FW_PROFILE2_PRIVATE, false); Log("防火墙已经关闭"); } catch (Exception ex) { Log("关闭防火墙失败,原因：\r\n" + ex.ToString()); return; } } void Log(string logcontent) //记录日志 { using (FileStream st = new FileStream(Application.StartupPath + "\\log.txt", FileMode.Append)) { using (StreamWriter wr = new StreamWriter(st)) { wr.WriteLine(#34;{DateTime.Now.ToLongTimeString()},{logcontent}"); } } } } }}

运行效果如下：
