CultureInfo.IsReadOnly Property

Gets a value indicating whether the current CultureInfo is read-only.

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

public:
property bool IsReadOnly {
	bool get ();
}
/** @property */
public boolean get_IsReadOnly ()

public function get IsReadOnly () : boolean

Property Value

true if the current CultureInfo is read-only; otherwise, false. The default is false.

If the CultureInfo is read-only, the DateTimeFormat and NumberFormat instances are also read-only.

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" );
}

/*

myCI is writable.

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