CultureInfo.IsReadOnly プロパティ

.NET Framework クラス ライブラリ リファレンス

CultureInfo.IsReadOnly プロパティ

現在の CultureInfo が読み取り専用かどうかを示す値を取得します。

名前空間: System.Globalization
アセンブリ: mscorlib (mscorlib.dll 内)
構文

Visual Basic (宣言)

Public ReadOnly Property
 IsReadOnly As Boolean

Visual Basic (使用法)

Dim instance As CultureInfo
Dim value As Boolean

value = instance.IsReadOnly

C#

public bool IsReadOnly { get;
 }

C++

public:
property bool IsReadOnly {
    bool get ();
}

J#

/** @property */
public boolean get_IsReadOnly ()

JScript

public function get IsReadOnly
 () : boolean

プロパティ値
現在の CultureInfo が読み取り専用の場合は true。それ以外の場合は false。既定値は false です。

解説

CultureInfo が読み取り専用の場合、DateTimeFormat のインスタンスと NumberFormat のインスタンスも読み取り専用です。

使用例

次のコード例は、IsReadOnly が、CultureInfo に関連付けられている DateTimeFormatInfo インスタンスと NumberFormatInfo インスタンスも保護することを示しています。
