OpenFirewall

1、写一份json文件：将要添加防火墙例外的应用程序和端口写入到json文件中

2、打开防火墙，读取json文件添加例外

    /// Firewall.xaml 的交互逻辑

            {
                ProcessStartInfo objProInfo = new ProcessStartInfo();

                }
            }
        }
    }

　　3、具体的一下实现方法

public static void OpenFireWall()
        {
            string cmdStr = "netsh advfirewall set currentprofile state on";
            //打开防火墙
            List<string> upCmd = new List<string>();
            upCmd.Add(("cd " + System.AppDomain.CurrentDomain.BaseDirectory));
            upCmd.Add(cmdStr);
            INetFireWallManger.Execute(upCmd);
        }

                }
                catch (Exception)
                {

                }
