範例

下列程式代碼範例會顯示已接收IP封包的統計數據。

void ShowInboundIPStatistics()
{
   IPGlobalProperties ^ properties = IPGlobalProperties::GetIPGlobalProperties();
   IPGlobalStatistics ^ ipstat = properties->GetIPv4GlobalStatistics();
   Console::WriteLine( "  Inbound Packet Data:" );
   Console::WriteLine( "      Received ............................ : {0}", 
      ipstat->ReceivedPackets );
   Console::WriteLine( "      Forwarded ........................... : {0}", 
      ipstat->ReceivedPacketsForwarded );
   Console::WriteLine( "      Delivered ........................... : {0}", 
      ipstat->ReceivedPacketsDelivered );
   Console::WriteLine( "      Discarded ........................... : {0}", 
      ipstat->ReceivedPacketsDiscarded );
}

public static void ShowInboundIPStatistics()
{
     IPGlobalProperties properties = IPGlobalProperties.GetIPGlobalProperties();
     IPGlobalStatistics ipstat = properties.GetIPv4GlobalStatistics();
     Console.WriteLine("  Inbound Packet Data:");
     Console.WriteLine("      Received ............................ : {0}",
     ipstat.ReceivedPackets);
     Console.WriteLine("      Forwarded ........................... : {0}",
     ipstat.ReceivedPacketsForwarded);
     Console.WriteLine("      Delivered ........................... : {0}",
     ipstat.ReceivedPacketsDelivered);
     Console.WriteLine("      Discarded ........................... : {0}",
     ipstat.ReceivedPacketsDiscarded);
}

Public Shared Sub ShowInboundIPStatistics() 
    Dim properties As IPGlobalProperties = IPGlobalProperties.GetIPGlobalProperties()
    Dim ipstat As IPGlobalStatistics = properties.GetIPv4GlobalStatistics()
    Console.WriteLine("  Inbound Packet Data:")
    Console.WriteLine("      Received ............................ : {0}", ipstat.ReceivedPackets)
    Console.WriteLine("      Forwarded ........................... : {0}", ipstat.ReceivedPacketsForwarded)
    Console.WriteLine("      Delivered ........................... : {0}", ipstat.ReceivedPacketsDelivered)
    Console.WriteLine("      Discarded ........................... : {0}", ipstat.ReceivedPacketsDiscarded)

End Sub

備註

此屬性傳回的值只會包含捨棄的封包，即使它們未包含防止重新組譯或傳遞的錯誤也一樣。 一般而言，因為緩衝區空間不足，所以會捨棄此類別中的封包。
