Specifies whether a property or parameter should be localized. This class cannot be inherited.

[System.AttributeUsage(System.AttributeTargets.All)]
public sealed class LocalizableAttribute : Attribute

[<System.AttributeUsage(System.AttributeTargets.All)>]
type LocalizableAttribute = class
    inherit Attribute

Examples

The following example marks the message parameter as needing to be localized.

public static void ShowMessage([Localizable(true)] string message)

The following example marks a property as needing to be localized.

public:
   property int MyProperty 
   {
      [Localizable(true)]
      int get()
      {
         // Insert code here.
         return 0;
      }

      void set( int value )
      {
         // Insert code here.
      }
   }

[Localizable(true)]
 public int MyProperty {
    get {
       // Insert code here.
       return 0;
    }
    set {
       // Insert code here.
    }
 }

<Localizable(True)> _
Public Property MyProperty() As Integer
    Get
        ' Insert code here.
        Return 0
    End Get
    Set
        ' Insert code here.
    End Set 
End Property

The next example shows how to check the value of the LocalizableAttribute for MyProperty. First, the code gets a PropertyDescriptorCollection with all the properties for the object. Then, the code gets MyProperty from the PropertyDescriptorCollection. Next, it returns the attributes for this property and saves them in the attributes variable.

Finally, the code sets myAttribute to the value of the LocalizableAttribute in the AttributeCollection and checks whether the property needs to be localized.

// Gets the attributes for the property.
AttributeCollection^ attributes = TypeDescriptor::GetProperties( this )[ "MyProperty" ]->Attributes;

// Checks to see if the property needs to be localized.
LocalizableAttribute^ myAttribute = dynamic_cast<LocalizableAttribute^>(attributes[ LocalizableAttribute::typeid ]);
if ( myAttribute->IsLocalizable )
{
   // Insert code here.
}

// Gets the attributes for the property.
AttributeCollection attributes = 
TypeDescriptor.GetProperties(this)["MyProperty"].Attributes;

// Checks to see if the property needs to be localized.
LocalizableAttribute myAttribute = 
(LocalizableAttribute)attributes[typeof(LocalizableAttribute)];
if(myAttribute.IsLocalizable) {
// Insert code here.
}

' Gets the attributes for the property.
Dim attributes As AttributeCollection = TypeDescriptor.GetProperties(Me)("MyProperty").Attributes

' Checks to see if the property needs to be localized.
Dim myAttribute As LocalizableAttribute = CType(attributes(GetType(LocalizableAttribute)), LocalizableAttribute)
If myAttribute.IsLocalizable Then
     ' Insert code here.
End If

Remarks

When code is generated for a component, members that are marked with the LocalizableAttribute set to true have their property values saved in resource files. You can localize these resource files without modifying the code.

By default, members that have no localizable attribute or are marked with the LocalizableAttribute set to false will have their property values persisted to code, if the data type allows. Otherwise, if the main component is set to Localizable, all properties will be persisted to the resource file. The default is false.

Note

When you mark a property with the LocalizableAttribute set to true, the value of this attribute is set to the constant member Yes. For a property marked with the LocalizableAttribute set to false, the value is No. Therefore, when you want to check the value of this attribute in your code, you must specify the attribute as LocalizableAttribute.Yes or LocalizableAttribute.No.

Constructors

LocalizableAttribute(Boolean)

Initializes a new instance of the LocalizableAttribute class.

Fields

Default	Specifies the default value, which is No. This static field is read-only.
No	Specifies that a property should not be localized. This static field is read-only.
Yes	Specifies that a property should be localized. This static field is read-only.

Properties

IsLocalizable	Gets a value indicating whether a property should be localized.
TypeId	When implemented in a derived class, gets a unique identifier for this Attribute. (Inherited from Attribute)

Methods

Equals(Object)	Returns whether the value of the given object is equal to the current LocalizableAttribute.
GetHashCode()	Returns the hash code for this instance.
GetType()	Gets the Type of the current instance. (Inherited from Object)
IsDefaultAttribute()	Determines if this attribute is the default.
Match(Object)	When overridden in a derived class, returns a value that indicates whether this instance equals a specified object. (Inherited from Attribute)
MemberwiseClone()	Creates a shallow copy of the current Object. (Inherited from Object)
ToString()	Returns a string that represents the current object. (Inherited from Object)
