NumberFormatInfo.IsReadOnly プロパティ
定義
この NumberFormatInfo オブジェクトが読み取り専用かどうかを示す値を取得します。Gets a value that indicates whether this NumberFormatInfo object is read-only.
public:
property bool IsReadOnly { bool get(); };
public bool IsReadOnly { get; }
member this.IsReadOnly : bool
Public ReadOnly Property IsReadOnly As Boolean
プロパティ値
true
が読み取り専用である場合は NumberFormatInfo。それ以外の場合は false
。true
if the NumberFormatInfo is read-only; otherwise, false
.
注釈
読み取り専用のプロパティへの割り当てを実行しようとすると NumberFormatInfo 、が発生 InvalidOperationException します。Attempting to perform an assignment to a property of a read-only NumberFormatInfo causes an InvalidOperationException.
Clone次の例に示すように、メソッドを呼び出して、読み取り専用のオブジェクトから読み取り/書き込みオブジェクトを作成でき NumberFormatInfo ます。You can call the Clone method to create a read/write NumberFormatInfo object from a read-only object, as the following example illustrates.
using System;
using System.Globalization;
public class Example
{
public static void Main()
{
NumberFormatInfo nfi = NumberFormatInfo.CurrentInfo;
Console.WriteLine("Read-Only: {0}\n", nfi.IsReadOnly);
NumberFormatInfo nfiw = (NumberFormatInfo) nfi.Clone();
Console.WriteLine("Read-Only: {0}", nfiw.IsReadOnly);
}
}
// The example displays the following output:
// Read-Only: True
//
// Read-Only: False
Imports System.Globalization
Module Example
Public Sub Main()
Dim nfi As NumberFormatInfo = NumberFormatInfo.CurrentInfo
Console.WriteLine("Read-Only: {0}", nfi.IsReadOnly)
Console.WriteLine()
Dim nfiw As NumberFormatInfo = CType(nfi.Clone(), NumberFormatInfo)
Console.WriteLine("Read-Only: {0}", nfiw.IsReadOnly)
End Sub
End Module
' The example displays the following output:
' Read-Only: True
'
' Read-Only: False
