使用性能计数器监视特定的端口

Question

Is there any way I can use Performance Counter to monitor all the traffic, but in a specific port?

I am doing:

GetCounterValue(_netRecvCounters[index], "Network Interface", "Bytes Received/sec", _instanceNames[index]):

double GetCounterValue(PerformanceCounter pc, string categoryName, string counterName, string instanceName)
    {
        pc.CategoryName = categoryName;
        pc.CounterName = counterName;
        pc.InstanceName = instanceName;
        return pc.NextValue();  
    }

But it seems to log everything

With performance counters, somebody has to explicitly provide each counter value to the registry. If nobody is providing the specific value you are looking for as input, then there is no way to get it out.
