UdpStatistics.IncomingDatagramsWithErrors 属性

定义

命名空间:

System.Net.NetworkInformation

程序集:

System.Net.NetworkInformation.dll

获取已收到但因错误端口信息以外的错误而放弃的用户数据报协议 (UDP) 数据报的数量。

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

public abstract long IncomingDatagramsWithErrors { get; }

member this.IncomingDatagramsWithErrors : int64

Public MustOverride ReadOnly Property IncomingDatagramsWithErrors As Long

属性值

Int64

Int64 值，指定接收到的但由于目标端口上缺少应用程序以外的其他原因而未能传递的 UDP 数据报的总数。

示例

下面的代码示例显示指定 Internet 协议版本的 UDP 统计信息。

void ShowUdpStatistics( NetworkInterfaceComponent version )
{
   IPGlobalProperties ^ properties = IPGlobalProperties::GetIPGlobalProperties();
   UdpStatistics ^ udpStat = nullptr;
   switch ( version )
   {
      case NetworkInterfaceComponent::IPv4:
         udpStat = properties->GetUdpIPv4Statistics();
         Console::WriteLine( "UDP IPv4 Statistics" );
         break;

      case NetworkInterfaceComponent::IPv6:
         udpStat = properties->GetUdpIPv6Statistics();
         Console::WriteLine( "UDP IPv6 Statistics" );
         break;

      default:
         throw gcnew ArgumentException( "version" );
         break;
   }
   Console::WriteLine( "  Datagrams Received ...................... : {0}", udpStat->DatagramsReceived );
   Console::WriteLine( "  Datagrams Sent .......................... : {0}", udpStat->DatagramsSent );
   Console::WriteLine( "  Incoming Datagrams Discarded ............ : {0}", udpStat->IncomingDatagramsDiscarded );
   Console::WriteLine( "  Incoming Datagrams With Errors .......... : {0}", udpStat->IncomingDatagramsWithErrors );
   Console::WriteLine( "  UDP Listeners ........................... : {0}", udpStat->UdpListeners );
   Console::WriteLine( "" );
}

public static void ShowUdpStatistics(NetworkInterfaceComponent version)
{
    IPGlobalProperties properties = IPGlobalProperties.GetIPGlobalProperties();
    UdpStatistics udpStat = null;

    switch (version)
    {
        case NetworkInterfaceComponent.IPv4:
            udpStat = properties.GetUdpIPv4Statistics();
            Console.WriteLine("UDP IPv4 Statistics");
            break;
        case NetworkInterfaceComponent.IPv6:
            udpStat = properties.GetUdpIPv6Statistics();
            Console.WriteLine("UDP IPv6 Statistics");
            break;
        default:
            throw new ArgumentException("version");
        //    break;
    }
    Console.WriteLine("  Datagrams Received ...................... : {0}",
        udpStat.DatagramsReceived);
    Console.WriteLine("  Datagrams Sent .......................... : {0}",
        udpStat.DatagramsSent);
    Console.WriteLine("  Incoming Datagrams Discarded ............ : {0}",
        udpStat.IncomingDatagramsDiscarded);
    Console.WriteLine("  Incoming Datagrams With Errors .......... : {0}",
        udpStat.IncomingDatagramsWithErrors);
    Console.WriteLine("  UDP Listeners ........................... : {0}",
        udpStat.UdpListeners);
    Console.WriteLine("");
}

注解

若要查找无法传递的数据报总数，请添加此属性和 IncomingDatagramsDiscarded 属性返回的值。
