IPGlobalStatistics.PacketFragmentFailures 属性

定义

命名空间:

System.Net.NetworkInformation

程序集:

System.Net.NetworkInformation.dll

获取未能分段的 Internet 协议 (IP) 数据包数。

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

属性值

Int64

Int64 值，它指定需要分段但设置了“不要分段”(Don't Fragment) 位的数据包总数。

属性

UnsupportedOSPlatformAttribute

示例

下面的代码示例显示 IP 数据包的重新组装统计信息。

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

注解

超出 IP 传输最大大小的数据包将分解为片段，并在目标处重新组合。 此属性返回的值指示需要为 IP 传输进行分段的数据包数，但不能是，因为数据包标头指定数据包不会分段。
