CultureInfo.IsReadOnly Propiedad

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

public bool IsReadOnly { get; }

member this.IsReadOnly : bool

Public ReadOnly Property IsReadOnly As Boolean

Valor de propiedad

true si el CultureInfo actual es de sólo lectura; en caso contrario, false. De manera predeterminada, es false.

Ejemplos

En el ejemplo de código siguiente se muestra que IsReadOnly también ayuda a proteger las DateTimeFormatInfo instancias y NumberFormatInfo asociadas a 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.

Si es de CultureInfo solo lectura, las DateTimeFormat instancias y NumberFormat también son de solo lectura.
