LocalizableAttribute Class


The .NET API Reference documentation has a new home. Visit the .NET API Browser on docs.microsoft.com to see the new experience.

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

Namespace:   System.ComponentModel
Assembly:  System (in System.dll)


public sealed class LocalizableAttribute : Attribute


Initializes a new instance of the LocalizableAttribute class.


Gets a value indicating whether a property should be localized.


When implemented in a derived class, gets a unique identifier for this Attribute.(Inherited from Attribute.)


Returns whether the value of the given object is equal to the current LocalizableAttribute.(Overrides Attribute.Equals(Object).)


Returns the hash code for this instance.(Overrides Attribute.GetHashCode().)


Gets the Type of the current instance.(Inherited from Object.)


Determines if this attribute is the default.(Overrides Attribute.IsDefaultAttribute().)


When overridden in a derived class, returns a value that indicates whether this instance equals a specified object.(Inherited from Attribute.)


Returns a string that represents the current object.(Inherited from Object.)


Specifies the default value, which is No. This static field is read-only.


Specifies that a property should not be localized. This static field is read-only.


Specifies that a property should be localized. This static field is read-only.

System_CAPS_pubinterfaceSystem_CAPS_privmethod_Attribute.GetIDsOfNames(Guid, IntPtr, UInt32, UInt32, IntPtr)

Maps a set of names to a corresponding set of dispatch identifiers.(Inherited from Attribute.)

System_CAPS_pubinterfaceSystem_CAPS_privmethod_Attribute.GetTypeInfo(UInt32, UInt32, IntPtr)

Retrieves the type information for an object, which can be used to get the type information for an interface.(Inherited from Attribute.)


Retrieves the number of type information interfaces that an object provides (either 0 or 1).(Inherited from Attribute.)

System_CAPS_pubinterfaceSystem_CAPS_privmethod_Attribute.Invoke(UInt32, Guid, UInt32, Int16, IntPtr, IntPtr, IntPtr, IntPtr)

Provides access to properties and methods exposed by an object.(Inherited from Attribute.)

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.


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.

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

 public int MyProperty {
    get {
       // Insert code here.
       return 0;
    set {
       // Insert code here.

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 = 

// Checks to see if the property needs to be localized.
LocalizableAttribute myAttribute = 
if(myAttribute.IsLocalizable) {
// Insert code here.
