Type: System.ComponentModelITypeDescriptorContext

An ITypeDescriptorContext that provides a format context.

Type: SystemObject

An Object that specifies the type of array for which to get properties.

Type: SystemAttribute

An array of type Attribute that is used as a filter.

Return Value

Type: System.ComponentModelPropertyDescriptorCollection
A PropertyDescriptorCollection with the properties that are exposed for this data type, or if there are no properties.

As implemented in this class, this method always returns .

Notes to Inheritors

Override this method if the type you want to convert supports properties.

Use the context parameter to extract additional information about the environment from which this converter is invoked. This parameter can be , so always check it. Also, properties on the context object can return .

The attributes array is used to filter the array. The attributes can have a mix of Type and Attribute objects. Filtering is defined by the following rules:

  • A Type is treated as a wildcard; it matches a property that has the Type in its set of attributes.

  • If a property does not have an Attribute of the same class, the property is not included in the returned array.

  • If the attribute is an instance of Attribute, the property must be an exact match or it is not included in the returned array.

  • If an Attribute instance is specified and it is the default property, it is included in the returned array even if there is no instance of the Attribute in the property.
