如何檢查防火牆規則是否存在

我有一個按鈕，一旦點擊後，它會向防火牆添加新規則。但問題是它可以多次點擊並添加許多規則。如何檢查防火牆規則是否存在

如何檢查規則是否存在於防火牆中？（或者是能夠檢驗規則？）

這裏是我的代碼添加一條規則：

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);

嘗試刪除現有規則，然後重新添加：），認爲簡單 – Oli

感謝您的最簡單的想法，從來沒有想過的：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...：}
