IPGlobalStatistics.PacketFragmentFailures Properti

Definisi

Ruang nama:

System.Net.NetworkInformation

Rakitan:

System.Net.NetworkInformation.dll

Mendapatkan jumlah paket Protokol Internet (IP) yang tidak dapat difragmentasi.

public:
 abstract property long PacketFragmentFailures { long get(); };

[System.Runtime.Versioning.UnsupportedOSPlatform("android")]
public abstract long PacketFragmentFailures { get; }

[<System.Runtime.Versioning.UnsupportedOSPlatform("android")>]
member this.PacketFragmentFailures : int64

Public MustOverride ReadOnly Property PacketFragmentFailures As Long

Nilai Properti

Int64

Nilai Int64 yang menentukan jumlah total paket yang memerlukan fragmentasi tetapi memiliki kumpulan bit "Jangan Fragmen".

Atribut

UnsupportedOSPlatformAttribute

Contoh

Contoh kode berikut menampilkan statistik penyusunan ulang untuk paket IP.

void ShowFragmentationStatistics()
{
   IPGlobalProperties ^ properties = IPGlobalProperties::GetIPGlobalProperties();
   IPGlobalStatistics ^ ipstat = properties->GetIPv4GlobalStatistics();
   Console::WriteLine( "  Reassembly Data:" );
   Console::WriteLine( "      Reassembly Timeout .................. : {0}", 
      ipstat->PacketReassemblyTimeout );
   Console::WriteLine( "      Reassemblies Required ............... : {0}", 
      ipstat->PacketReassembliesRequired );
   Console::WriteLine( "      Packets Reassembled ................. : {0}", 
      ipstat->PacketsReassembled );
   Console::WriteLine( "      Packets Fragmented .................. : {0}", 
      ipstat->PacketsFragmented );
   Console::WriteLine( "      Fragment Failures ................... : {0}", 
      ipstat->PacketFragmentFailures );
}

public static void ShowFragmentationStatistics()
{
    IPGlobalProperties properties = IPGlobalProperties.GetIPGlobalProperties();
    IPGlobalStatistics ipstat = properties.GetIPv4GlobalStatistics();
    Console.WriteLine("  Reassembly Data:");
    Console.WriteLine("      Reassembly Timeout .................. : {0}",
        ipstat.PacketReassemblyTimeout);
    Console.WriteLine("      Reassemblies Required ............... : {0}",
        ipstat.PacketReassembliesRequired);
    Console.WriteLine("      Packets Reassembled ................. : {0}",
        ipstat.PacketsReassembled);
    Console.WriteLine("      Packets Fragmented .................. : {0}",
        ipstat.PacketsFragmented);
    Console.WriteLine("      Fragment Failures ................... : {0}",
        ipstat.PacketFragmentFailures);
}

Public Shared Sub ShowFragmentationStatistics() 
    Dim properties As IPGlobalProperties = IPGlobalProperties.GetIPGlobalProperties()
    Dim ipstat As IPGlobalStatistics = properties.GetIPv4GlobalStatistics()
    Console.WriteLine("  Reassembly Data:")
    Console.WriteLine("      Reassembly Timeout .................. : {0}", ipstat.PacketReassemblyTimeout)
    Console.WriteLine("      Reassemblies Required ............... : {0}", ipstat.PacketReassembliesRequired)
    Console.WriteLine("      Packets Reassembled ................. : {0}", ipstat.PacketsReassembled)
    Console.WriteLine("      Packets Fragmented .................. : {0}", ipstat.PacketsFragmented)
    Console.WriteLine("      Fragment Failures ................... : {0}", ipstat.PacketFragmentFailures)

End Sub

Keterangan

Paket yang melebihi ukuran maksimum untuk transportasi IP dipecah menjadi fragmen dan disusun ulang di tujuan. Nilai yang dikembalikan oleh properti ini menunjukkan jumlah paket yang perlu difragmentasi untuk transportasi IP tetapi tidak bisa karena header paket menentukan bahwa paket tidak terfragmentasi.
