NumberFormatInfo.IsReadOnly 属性

定义

命名空间:

System.Globalization

程序集:

System.Globalization.dll

程序集:

System.Runtime.dll

程序集:

netstandard.dll

程序集:

mscorlib.dll

获取一个值，该值指示 NumberFormatInfo 对象是否为只读。

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

public bool IsReadOnly { get; }

member this.IsReadOnly : bool

Public ReadOnly Property IsReadOnly As Boolean

属性值

Boolean

如果 true 是只读的，则为 NumberFormatInfo；否则为 false。

注解

尝试对只读 的属性执行赋值会导致 NumberFormatInfo InvalidOperationException 。

可以调用 Clone 方法从只读对象创建读/写对象 NumberFormatInfo ，如以下示例所示。

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
