定義

命名空間:

System.Net.NetworkInformation

組件:

System.Net.NetworkInformation.dll

取得已在本機電腦 (Local Machine) 上收到，且標頭中含有未知通訊協定的網際網路通訊協定 (IP) 封包數目。

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

屬性值

Int64

Int64 值，指定已收到且具有未知通訊協定的 IP 封包總數。

屬性

UnsupportedOSPlatformAttribute

範例

下列程式代碼範例會顯示已接收IP封包的統計數據，並出現錯誤。

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

備註

IP 標頭中的通訊協定欄位表示 IP 資料報數據報數據部分所使用的下一層通訊協定。 如果無法辨識通訊協定，就無法將數據傳遞至正確的應用程式。
