IPGlobalProperties::GetIPv4GlobalStatistics Method ()

 

Provides Internet Protocol version 4 (IPv4) statistical data for the local computer.

Namespace:   System.Net.NetworkInformation
Assembly:  System (in System.dll)

public:
virtual IPGlobalStatistics^ GetIPv4GlobalStatistics() abstract

Return Value

Type: System.Net.NetworkInformation::IPGlobalStatistics^

An IPGlobalStatistics object that provides IPv4 traffic statistics for the local computer.

Exception Condition
NetworkInformationException

The call to the Win32 function GetIpStatistics failed.

IPv4 is a network layer protocol that is responsible for routing data packets from its source computer to its destination.

For details on the IP traffic statistics available to applications, see the IPGlobalStatistics class documentation. Note that the object returned by this method reflects the statistics as of the time the IPGlobalStatistics object is created. This information is not updated dynamically.

The following code example displays IP statistics for the local computer.

void ShowIPStatistics( NetworkInterfaceComponent version )
{
   IPGlobalProperties ^ properties = IPGlobalProperties::GetIPGlobalProperties();
   IPGlobalStatistics ^ ipstat = nullptr;
   switch ( version )
   {
      case NetworkInterfaceComponent::IPv4:
         ipstat = properties->GetIPv4GlobalStatistics();
         Console::WriteLine( "{0}IPv4 Statistics ", Environment::NewLine );
         break;

      case NetworkInterfaceComponent::IPv6:
         ipstat = properties->GetIPv4GlobalStatistics();
         Console::WriteLine( "{0}IPv6 Statistics ", Environment::NewLine );
         break;

      default:
         throw gcnew ArgumentException( "version" );
         break;
   }
