如何检查防火墙规则是否存在

我有一个按钮，一旦点击后，它会向防火墙添加新规则。但问题是它可以多次点击并添加许多规则。如何检查防火墙规则是否存在

如何检查规则是否存在于防火墙中？（或者是能够检验规则？）

这里是我的代码添加一条规则：

ProcessStartInfo run = new ProcessStartInfo(); 
run.FileName = "cmd.exe"; 
run.Verb = "runas"; 
run.Arguments = "/C netsh advfirewall firewall add rule name=\"Block IP Rule\" dir=in interface=any action=block remoteip=x.x.x.x"; 
run.WindowStyle = ProcessWindowStyle.Hidden; 
Process.Start(run);

尝试删除现有规则，然后重新添加：），认为简单 – Oli

感谢您的最简单的想法，从来没有想过的：D – newbieguy

public static void RemoveFirewallRules(string RuleName = "BreakermindCom") 
{ 
    try 
    { 
     Type tNetFwPolicy2 = Type.GetTypeFromProgID("HNetCfg.FwPolicy2"); 
     INetFwPolicy2 fwPolicy2 = (INetFwPolicy2)Activator.CreateInstance(tNetFwPolicy2); 
     var currentProfiles = fwPolicy2.CurrentProfileTypes;    

     // Lista rules 
     List<INetFwRule> RuleList = new List<INetFwRule>(); 

     foreach (INetFwRule rule in fwPolicy2.Rules) 
     { 
      // Add rule to list 
      //RuleList.Add(rule); 
      // Console.WriteLine(rule.Name); 
      if (rule.Name.IndexOf(RuleName) != -1) 
      { 
       // Now add the rule 
       INetFwPolicy2 firewallPolicy = (INetFwPolicy2)Activator.CreateInstance(Type.GetTypeFromProgID("HNetCfg.FwPolicy2"));      
       firewallPolicy.Rules.Remove(rule.Name); 
       Console.WriteLine(rule.Name + " has been deleted from Firewall Policy"); 
      } 
     } 
    } 
    catch (Exception r) 
    { 
     Console.WriteLine("Error delete rule from firewall"); 
    }}

作品...：}
