TypeDescriptor.GetEvents Method (Type, Attribute[])

 

Returns the collection of events for a specified type of component using a specified array of attributes as a filter.

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

public static EventDescriptorCollection GetEvents(
	Type componentType,
	Attribute[] attributes
)

Parameters

componentType
Type: System.Type

The Type of the target component.

attributes
Type: System.Attribute[]

An array of type Attribute that you can use as a filter.

Return Value

Type: System.ComponentModel.EventDescriptorCollection

An EventDescriptorCollection with the events that match the specified attributes for this component.

Call this version of this method only when you do not have an instance of the object.

The attributes parameter array 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 any event that has the Type in its set of attributes.

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

  • If the attribute is an instance of the Attribute class, the event 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 event, it is included in the returned array even if there is no instance of the Attribute in the event.

If the componentType parameter is null, an empty collection is returned.

The order of the returned collection is not guaranteed to be identical between calls, so always order it before use.
