NumberFormatInfo.IsReadOnly Property

 

Gets a value that indicates whether this NumberFormatInfo object is read-only.

Namespace:   System.Globalization
Assembly:  mscorlib (in mscorlib.dll)

public bool IsReadOnly { get; }

Property Value

Type: System.Boolean

true if the NumberFormatInfo is read-only; otherwise, false.

Attempting to perform an assignment to a property of a read-only NumberFormatInfo causes an InvalidOperationException.

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
