IPGlobalProperties.GetTcpIPv6Statistics 方法

定義

提供本機電腦的傳輸控制通訊協定/網際網路通訊協定第 6 版 (TCP/IPv6) 統計資料。

public:
 abstract System::Net::NetworkInformation::TcpStatistics ^ GetTcpIPv6Statistics();
public abstract System.Net.NetworkInformation.TcpStatistics GetTcpIPv6Statistics ();
[System.Runtime.Versioning.UnsupportedOSPlatform("android")]
public abstract System.Net.NetworkInformation.TcpStatistics GetTcpIPv6Statistics ();

[<System.Runtime.Versioning.UnsupportedOSPlatform("android")>]
abstract member GetTcpIPv6Statistics : unit -> System.Net.NetworkInformation.TcpStatistics
Public MustOverride Function GetTcpIPv6Statistics () As TcpStatistics

傳回

TcpStatistics 物件,其提供本機電腦的 TCP/IPv6 流量統計資料。

屬性

例外狀況

呼叫 Win32 函式 GetTcpStatistics 失敗。

本機電腦並非執行支援 IPv6 的作業系統。

範例

下列範例會顯示本機計算機的 TCP/IP 統計數據。

備註

TCP 是一種傳輸層通訊協議,負責可靠地傳送和接收數據封包。 它定義於 IETF RFC 793 中。

如需應用程式可用之 TCP 流量統計資料的詳細資訊,請參閱 TcpStatistics 類別檔。 請注意,這個方法所傳回的物件會反映建立物件時所傳回的 TcpStatistics 統計數據。 這項資訊不會動態更新。
