CultureInfo.IsReadOnly Свойство

Определение

Возвращает значение, указывающее, является ли текущий объект CultureInfo доступным только для чтения.Gets a value indicating whether the current CultureInfo is read-only.

public:
 property bool IsReadOnly { bool get(); };
public bool IsReadOnly { get; }
member this.IsReadOnly : bool
Public ReadOnly Property IsReadOnly As Boolean

Значение свойства

Значение true, если текущий объект CultureInfo доступен только для чтения, в противном случае — значение false.true if the current CultureInfo is read-only; otherwise, false. Значение по умолчанию — false.The default is false.

Примеры

В следующем примере кода показано, что IsReadOnly также помогает защитить экземпляры DateTimeFormatInfo и NumberFormatInfo, связанные с CultureInfo.The following code example shows that IsReadOnly also helps protect the DateTimeFormatInfo and NumberFormatInfo instances associated with the CultureInfo.

using namespace System;
using namespace System::Globalization;
int main()
{
   
   // Creates a CultureInfo.
   CultureInfo^ myCI = gcnew 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 ? (String^)"read only" : "writable" );
   Console::WriteLine( "myCI -> DateTimeFormat is {0}.", myCI->DateTimeFormat->IsReadOnly ? (String^)"read only" : "writable" );
   Console::WriteLine( "myCI -> NumberFormat is {0}.", myCI->NumberFormat->IsReadOnly ? (String^)"read only" : "writable" );
   Console::WriteLine( "myReadOnlyCI is {0}.", myReadOnlyCI->IsReadOnly ? (String^)"read only" : "writable" );
   Console::WriteLine( "myReadOnlyCI -> DateTimeFormat is {0}.", myReadOnlyCI->DateTimeFormat->IsReadOnly ? (String^)"read only" : "writable" );
   Console::WriteLine( "myReadOnlyCI -> NumberFormat is {0}.", myReadOnlyCI->NumberFormat->IsReadOnly ? (String^)"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.

Комментарии

Если CultureInfo доступен только для чтения, экземпляры DateTimeFormat и NumberFormat также доступны только для чтения.If the CultureInfo is read-only, the DateTimeFormat and NumberFormat instances are also read-only.
