Rule is not created expectedly

Question

Hi,
What is wrong below? I want to call Command prompt (by running it as Administrator) and further apply firewall rule. It seems relevant rule is not created expectedly. Why?

                                            fld1 = "netsh advfirewall firewall add rule name=\"Rule " + DateTime.Now.ToString() + "_" + Convert.ToString(cnt3).Trim() + "\" dir=in action=block remoteip=" + fld0 + ".1.1-" + fld0 + ".255.255";
                                            System.Diagnostics.Process.Start("CMD.exe", fld1);

Hi Jackson1990-7147,
Based on your code, you need to change "action=block" to "action=allow".
Then you need to pass an argument to cmd.exe via following code:

System.Diagnostics.ProcessStartInfo proc = new System.Diagnostics.ProcessStartInfo();  
proc.FileName = "CMD.exe";  
proc.Arguments ="/k "+f1d1;  
System.Diagnostics.Process.Start(proc);  

For more information about how to add firewall rules, run the following command:

netsh advfirewall firewall add rule ?  

And here is a useful document you can refer to.

Many thanks.
Is there a way to ensure that CMD process would be closed after being run, as there would be many pending CMD session, if I have a looping to generate that?
