IPGlobalStatistics.PacketReassemblyTimeout 屬性

定義

命名空間:

System.Net.NetworkInformation

組件:

System.Net.NetworkInformation.dll

取得時間上限，網際網路通訊協定 (IP) 封包的所有片段都必須在該時間內到達。

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

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

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

Public MustOverride ReadOnly Property PacketReassemblyTimeout As Long

屬性值

Int64

Int64 值，指定最大毫秒數，封包的所有片段都必須在該時間內到達才能避免遭捨棄。

屬性

UnsupportedOSPlatformAttribute

範例

下列程式代碼範例會顯示IP封包的重新組譯統計數據。

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

備註

超過IP傳輸大小上限的封包會分成片段，並在目的地重新組譯。 如果組成分散IP封包的所有片段都未在允許的時間內送達，則會捨棄封包。
