TypeDescriptor.AddAttributes Method (Object, Attribute[])

Adds class-level attributes to the target component instance.

Namespace:  System.ComponentModel
Assembly:  System (in System.dll)
[PermissionSetAttribute(SecurityAction.LinkDemand, Name = "FullTrust")]
public static TypeDescriptionProvider AddAttributes(
	Object instance,
	params Attribute[] attributes
)

Parameters

instance
Type: System.Object
An instance of the target component.
attributes
Type: System.Attribute[]
An array of Attribute objects to add to the component's class.

Return Value

Type: System.ComponentModel.TypeDescriptionProvider
The newly created TypeDescriptionProvider that was used to add the specified attributes.
ExceptionCondition
ArgumentNullException

One or both of the parameters is null.

The AddAttributes(Object, Attribute[]) method adds class-level attributes to the specified instance of a component. Because this is a common requirement of applications using the Visual Studio Windows Forms Designer and Properties window, this method provides a shortcut by creating a type description provider that merges the provided attributes with the attributes that already exist on the class. The return value is the type description provider that was used to add the attributes. This provider can later be passed to the RemoveProvider(TypeDescriptionProvider, Object) method when the added attributes are no longer needed.
