获取已收到但被丢弃的 Internet 协议 (IP) 数据包数。

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

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

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

Public MustOverride ReadOnly Property ReceivedPacketsDiscarded As Long

属性值

Int64

Int64 值，它指定已丢弃的传入数据包的总数。

属性

UnsupportedOSPlatformAttribute

示例

下面的代码示例显示收到的 IP 数据包的统计信息。

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

注解

此属性返回的值仅包括那些被丢弃的数据包，即使它们不包含阻止重新组装或传递的错误。 通常，由于缓冲区空间不足，此类别中的数据包将被丢弃。
