调用代码:
private static void AddToFireWall()
{if (FirewallHelper.Instance.HasAuthorization(Environment.ProcessPath)){Console.WriteLine("有防火墙权限");}else{Console.WriteLine("没有防火墙权限");FirewallHelper.Instance.GrantAuthorization(Environment.ProcessPath, Path.GetFileNameWithoutExtension(Environment.ProcessPath));}
