IPGlobalStatistics.ReceivedPacketsWithUnknownProtocol 属性

定义

命名空间:

System.Net.NetworkInformation

程序集:

System.Net.NetworkInformation.dll

获取在本地计算机上收到的、标头中有未知协议的 Internet 协议 (IP) 数据包数。

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

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

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

Public MustOverride ReadOnly Property ReceivedPacketsWithUnknownProtocol As Long

属性值

Int64

Int64 值，它指示收到的、协议未知的 IP 数据包的总数。

属性

UnsupportedOSPlatformAttribute

示例

下面的代码示例显示包含错误的已接收 IP 数据包的统计信息。

void ShowInboundIPErrors()
{
   IPGlobalProperties ^ properties = IPGlobalProperties::GetIPGlobalProperties();
   IPGlobalStatistics ^ ipstat = properties->GetIPv4GlobalStatistics();
   Console::WriteLine( "  Inbound Packet Errors:" );
   Console::WriteLine( "      Header Errors ....................... : {0}", 
      ipstat->ReceivedPacketsWithHeadersErrors );
   Console::WriteLine( "      Address Errors ...................... : {0}", 
      ipstat->ReceivedPacketsWithAddressErrors );
   Console::WriteLine( "      Unknown Protocol Errors ............. : {0}", 
      ipstat->ReceivedPacketsWithUnknownProtocol );
}

public static void ShowInboundIPErrors()
{
    IPGlobalProperties properties = IPGlobalProperties.GetIPGlobalProperties();
    IPGlobalStatistics ipstat = properties.GetIPv4GlobalStatistics();
    Console.WriteLine("  Inbound Packet Errors:");
    Console.WriteLine("      Header Errors ....................... : {0}",
        ipstat.ReceivedPacketsWithHeadersErrors);
    Console.WriteLine("      Address Errors ...................... : {0}",
        ipstat.ReceivedPacketsWithAddressErrors);
    Console.WriteLine("      Unknown Protocol Errors ............. : {0}",
        ipstat.ReceivedPacketsWithUnknownProtocol);
}

Public Shared Sub ShowInboundIPErrors() 
    Dim properties As IPGlobalProperties = IPGlobalProperties.GetIPGlobalProperties()
    Dim ipstat As IPGlobalStatistics = properties.GetIPv4GlobalStatistics()
    Console.WriteLine("  Inbound Packet Errors:")
    Console.WriteLine("      Header Errors ....................... : {0}", ipstat.ReceivedPacketsWithHeadersErrors)
    Console.WriteLine("      Address Errors ...................... : {0}", ipstat.ReceivedPacketsWithAddressErrors)
    Console.WriteLine("      Unknown Protocol Errors ............. : {0}", ipstat.ReceivedPacketsWithUnknownProtocol)

End Sub

注解

IP 标头中的协议字段指示 IP 数据报的数据部分中使用的下一级协议。 如果未识别协议，则无法将数据传递到正确的应用程序。
