CultureInfo.CurrentCulture プロパティ

  • [アーティクル]

現在のスレッドで使用するカルチャを表す CultureInfo を取得します。

Public Shared ReadOnly Property CurrentCulture As CultureInfo
[C#]
public static CultureInfo CurrentCulture {get;}
[C++]
public: __property static CultureInfo* get_CurrentCulture();
[JScript]
public static function get CurrentCulture() : CultureInfo;

プロパティ値

現在のスレッドで使用するカルチャを表す CultureInfo 。

解説

取得されるカルチャは、実行中のスレッドのプロパティです。この読み取り専用プロパティは、 Thread.CurrentCulture を返します。スレッドを開始すると、そのカルチャは、最初に Windows API から GetUserDefaultLCID を使用することによって確認されます。スレッドが使用するカルチャを変更するには、 Thread.CurrentCulture を新しいカルチャに設定します。 Thread.CurrentThread のカルチャを変更するには、 ControlThread フラグの設定された SecurityPermission が必要です。スレッドに関連付けられているセキュリティ状態が理由で、スレッド操作は危険です。このため、このアクセス許可は、信頼できるコードに必要な場合だけ与えてください。信頼度の低いコード内では、スレッドのカルチャは変更できません。

使用例

[Visual Basic, C#, C++] 現在のスレッドの CurrentCulture と CurrentUICulture を変更する方法を次のコード例に示します。

   Public Shared Sub Main()

      ' Displays the name of the CurrentCulture of the current thread.
      Console.WriteLine("CurrentCulture is {0}.", CultureInfo.CurrentCulture.Name)

      ' Changes the CurrentCulture of the current thread to th-TH.
      Thread.CurrentThread.CurrentCulture = New CultureInfo("th-TH", False)
      Console.WriteLine("CurrentCulture is now {0}.", CultureInfo.CurrentCulture.Name)

      ' Displays the name of the CurrentUICulture of the current thread.
      Console.WriteLine("CurrentUICulture is {0}.", CultureInfo.CurrentUICulture.Name)

      ' Changes the CurrentUICulture of the current thread to ja-JP.
      Thread.CurrentThread.CurrentUICulture = New CultureInfo("ja-JP", False)
      Console.WriteLine("CurrentUICulture is now {0}.", CultureInfo.CurrentUICulture.Name)
