HttpCapabilitiesBase.Version 屬性

  • 參考

定義

命名空間:
System.Web.Configuration
組件:
System.Web.dll

取得瀏覽器的完整版本號碼 (整數和小數) 並以字串表示。

public:
 property System::String ^ Version { System::String ^ get(); };
public string Version { get; }
member this.Version : string
Public ReadOnly Property Version As String

屬性值

String

瀏覽器的完整版本號碼並以字串表示。

範例

下列程式碼範例示範如何判斷 Version 瀏覽器的 。 屬性 MajorVersion 和 MinorVersion 屬性會串連，而結果會用來判斷瀏覽器版本是否大於 5.01。

備註

屬性會 Version 傳回字串。 在某些情況下， Version 屬性可能包含字母字元，如同瀏覽器或用戶端裝置的 Beta 版本，例如 「7.0b」。若要正確取得版本作為可用於數值比較的資料類型，請串連 MajorVersion 和 MinorVersion 屬性值。
