Golang：替代C＃（。Net）IPGlobalProperties.GetIPGlobalProperties（）

I am rewriting one of my windows service(C#) in Golang. I have almost figured out and rewrote the code in Go but got stuck at one place where I am not been able to figure out golang alternative.

public static int GetNumberOfLocalEstablishedConnectionsByPort(string IPAddress, int Port)
    {
        int Result = 0;
        IPGlobalProperties ipProperties = IPGlobalProperties.GetIPGlobalProperties();
        TcpConnectionInformation[] tcpConnections = ipProperties.GetActiveTcpConnections();

        foreach (TcpConnectionInformation tcpInfo in tcpConnections)
        {
                if (tcpInfo.State == TcpState.Established && tcpInfo.LocalEndPoint.Port == Port) 
                {
                            Result++;
                }
        }

        return Result;
    }

Basically in this method I am finding out active number of connections based on a IP address and Port.

I am seeking help in order to find out how can I rewrite this C# code into Golang. I am using windows OS and want a solution based on Windows OS

In order to find the number of active connections, there is no equivalent wrapper similar to above-mentioned C# methods in Golang.

Though we can achieve this using the syscalls for this we can use the following command if you are Linux user.

netstat -anp | grep :80 | grep ESTABLISHED | wc -l

However, in windows os, you might face some problem because grep and wc (word count) command will not work. I faced this problem when I ran it as a windows service.

For Windows OS the following command worked.

netstat -nt | findstr :80  | findstr ESTABLISHED | find /v /c ""

For /v /c to work you might need to make the exe file execute as administrator .
