 property bool IsReadOnly { bool get(); };

public bool IsReadOnly { get; }

member this.IsReadOnly : bool

Public ReadOnly Property IsReadOnly As Boolean

Valeur de propriété

Boolean

true si le CultureInfo actuel est en lecture seule ; sinon, false. La valeur par défaut est false.

Exemples

L’exemple de code suivant montre que IsReadOnly permet également de protéger les DateTimeFormatInfo instances et NumberFormatInfo associées au 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.

      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" );

Si est CultureInfo en lecture seule, les DateTimeFormat instances et NumberFormat sont également en lecture seule.
