 abstract System::Net::NetworkInformation::UdpStatistics ^ GetUdpIPv4Statistics();
public abstract System.Net.NetworkInformation.UdpStatistics GetUdpIPv4Statistics ();
[System.Runtime.Versioning.UnsupportedOSPlatform("android")]
public abstract System.Net.NetworkInformation.UdpStatistics GetUdpIPv4Statistics ();
abstract member GetUdpIPv4Statistics : unit -> System.Net.NetworkInformation.UdpStatistics
[<System.Runtime.Versioning.UnsupportedOSPlatform("android")>]
abstract member GetUdpIPv4Statistics : unit -> System.Net.NetworkInformation.UdpStatistics
Public MustOverride Function GetUdpIPv4Statistics () As UdpStatistics

Mengembalikan

Objek UdpStatistics yang menyediakan statistik lalu lintas UDP/IPv4 untuk komputer lokal.

Atribut

Pengecualian

Panggilan ke fungsi Win32 GetUdpStatistics gagal.

Contoh

Contoh berikut menampilkan statistik UDP/IP untuk komputer lokal.

void ShowUdpStatistics( NetworkInterfaceComponent version )
{
   IPGlobalProperties ^ properties = IPGlobalProperties::GetIPGlobalProperties();
   UdpStatistics ^ udpStat = nullptr;
   switch ( version )
   {
      case NetworkInterfaceComponent::IPv4:
         udpStat = properties->GetUdpIPv4Statistics();
         Console::WriteLine( "UDP IPv4 Statistics" );
         break;

      case NetworkInterfaceComponent::IPv6:
         udpStat = properties->GetUdpIPv6Statistics();
         Console::WriteLine( "UDP IPv6 Statistics" );
         break;

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

Keterangan

UDP adalah protokol lapisan transportasi tanpa koneksi yang bertanggung jawab untuk mengirim dan menerima datagram. Ini didefinisikan dalam IETF RFC 768.

Untuk detail tentang statistik lalu lintas UDP yang tersedia untuk aplikasi, lihat UdpStatistics dokumentasi kelas. Perhatikan bahwa objek yang dikembalikan oleh metode ini mencerminkan statistik pada saat UdpStatistics objek dibuat. Informasi ini tidak diperbarui secara dinamis.
