例

次のコード例では、エラーが発生した受信 IP パケットの統計情報を表示します。

void ShowInboundIPErrors()
{
   IPGlobalProperties ^ properties = IPGlobalProperties::GetIPGlobalProperties();
   IPGlobalStatistics ^ ipstat = properties->GetIPv4GlobalStatistics();
   Console::WriteLine( "  Inbound Packet Errors:" );
   Console::WriteLine( "      Header Errors ....................... : {0}", 
      ipstat->ReceivedPacketsWithHeadersErrors );
   Console::WriteLine( "      Address Errors ...................... : {0}", 
      ipstat->ReceivedPacketsWithAddressErrors );
   Console::WriteLine( "      Unknown Protocol Errors ............. : {0}", 
      ipstat->ReceivedPacketsWithUnknownProtocol );
}

public static void ShowInboundIPErrors()
{
    IPGlobalProperties properties = IPGlobalProperties.GetIPGlobalProperties();
    IPGlobalStatistics ipstat = properties.GetIPv4GlobalStatistics();
    Console.WriteLine("  Inbound Packet Errors:");
    Console.WriteLine("      Header Errors ....................... : {0}",
        ipstat.ReceivedPacketsWithHeadersErrors);
    Console.WriteLine("      Address Errors ...................... : {0}",
        ipstat.ReceivedPacketsWithAddressErrors);
    Console.WriteLine("      Unknown Protocol Errors ............. : {0}",
        ipstat.ReceivedPacketsWithUnknownProtocol);
}

Public Shared Sub ShowInboundIPErrors() 
    Dim properties As IPGlobalProperties = IPGlobalProperties.GetIPGlobalProperties()
    Dim ipstat As IPGlobalStatistics = properties.GetIPv4GlobalStatistics()
    Console.WriteLine("  Inbound Packet Errors:")
    Console.WriteLine("      Header Errors ....................... : {0}", ipstat.ReceivedPacketsWithHeadersErrors)
    Console.WriteLine("      Address Errors ...................... : {0}", ipstat.ReceivedPacketsWithAddressErrors)
