CultureInfo.IsReadOnly 屬性

定義

命名空間:

System.Globalization

組件:

System.Runtime.dll

來源:

CultureInfo.cs

取得值，指出目前 CultureInfo 是否唯讀。

C#

public bool IsReadOnly { get; }

屬性值

Boolean

如果目前 true 是唯讀，則為 CultureInfo，否則為 false。 預設為 false。

範例

下列程式代碼範例示範也IsReadOnly有助於保護 DateTimeFormatInfo 與相關聯的CultureInfo和 NumberFormatInfo 實例。

C#

using System;
using System.Globalization;

public class SamplesCultureInfo  {

   public static void Main()  {

      // Creates a CultureInfo.
      CultureInfo myCI = new CultureInfo( "en-US" );

      // Creates a read-only CultureInfo based on myCI.
      CultureInfo myReadOnlyCI = CultureInfo.ReadOnly( myCI );

      // Display the read-only status of each CultureInfo and their DateTimeFormat and NumberFormat properties.
      Console.WriteLine( "myCI is {0}.", myCI.IsReadOnly ? "read only" : "writable" );
      Console.WriteLine( "myCI.DateTimeFormat is {0}.", myCI.DateTimeFormat.IsReadOnly ? "read only" : "writable" );
      Console.WriteLine( "myCI.NumberFormat is {0}.", myCI.NumberFormat.IsReadOnly ? "read only" : "writable" );
      Console.WriteLine( "myReadOnlyCI is {0}.", myReadOnlyCI.IsReadOnly ? "read only" : "writable" );
      Console.WriteLine( "myReadOnlyCI.DateTimeFormat is {0}.", myReadOnlyCI.DateTimeFormat.IsReadOnly ? "read only" : "writable" );
      Console.WriteLine( "myReadOnlyCI.NumberFormat is {0}.", myReadOnlyCI.NumberFormat.IsReadOnly ? "read only" : "writable" );
   }
}

/*
This code produces the following output.

myCI is writable.
myCI.DateTimeFormat is writable.
myCI.NumberFormat is writable.
myReadOnlyCI is read only.
myReadOnlyCI.DateTimeFormat is read only.
myReadOnlyCI.NumberFormat is read only.

*/

備註

CultureInfo如果 是唯讀的，DateTimeFormat和 NumberFormat 實例也是唯讀的。
