No code example is currently available or this language may not be supported.

The EventInfo type exposes the following members.

	Name	Description
	AddMethod	Gets the MethodInfo object for the AddEventHandler method of the event, including non-public methods.
	Attributes	Gets the attributes for this event.
	CustomAttributes	Gets a collection that contains this member's custom attributes. (Inherited from MemberInfo.)
	DeclaringType	Gets the class that declares this member. (Inherited from MemberInfo.)
	EventHandlerType	Gets the Type object of the underlying event-handler delegate associated with this event.
	IsMulticast	Gets a value that indicates whether the event is multicast.
	IsSpecialName	Gets a value that indicates whether the EventInfo has a name with a special meaning.
	MemberType	Gets a MemberTypes value indicating that this member is an event. (Overrides MemberInfo::MemberType.)
	MetadataToken	Gets a value that identifies a metadata element. (Inherited from MemberInfo.)
	Module	Gets the module in which the type that declares the member represented by the current MemberInfo is defined. (Inherited from MemberInfo.)
	Name	Gets the name of the current member. (Inherited from MemberInfo.)
	RaiseMethod	Gets the method that is called when the event is raised, including non-public methods.
	ReflectedType	Gets the class object that was used to obtain this instance of MemberInfo. (Inherited from MemberInfo.)
	RemoveMethod	Gets the MethodInfo object for removing a method of the event, including non-public methods.

	Name	Description
	AddEventHandler	Adds an event handler to an event source.
	Equals	Returns a value that indicates whether this instance is equal to a specified object. (Overrides MemberInfo::Equals(Object).)
	Finalize	Allows an object to try to free resources and perform other cleanup operations before the Object is reclaimed by garbage collection. (Inherited from Object.)
	GetAddMethod()	Returns the method that is used to add an event-handler delegate to the event source.
	GetAddMethod(Boolean)	When overridden in a derived class, returns the method that is used to add an event-handler delegate to the event source, specifying whether to return the method if the current event is non-public.
	GetCustomAttributes(Boolean)	When overridden in a derived class, returns an array of all custom attributes applied to this member. (Inherited from MemberInfo.)
	GetCustomAttributes(Type, Boolean)	When overridden in a derived class, returns an array of custom attributes applied to this member and identified by Type. (Inherited from MemberInfo.)
	GetHashCode	Returns the hash code for this instance. (Overrides MemberInfo::GetHashCode().)
	GetRaiseMethod()	Returns the method that is called when the event is raised.
	GetRaiseMethod(Boolean)	When overridden in a derived class, returns the method that is called when the event is raised, specifying whether to return non-public methods.
	GetRemoveMethod()	Returns the method that is used to remove an event-handler delegate from the event source.
	GetRemoveMethod(Boolean)	When overridden in a derived class, retrieves the MethodInfo object for removing a method of the event, specifying whether to return non-public methods.
	GetType	Gets the Type of the current instance. (Inherited from Object.)
	IsDefined	When overridden in a derived class, indicates whether one or more attributes of the specified type or of its derived types is applied to this member. (Inherited from MemberInfo.)
	MemberwiseClone	Creates a shallow copy of the current Object. (Inherited from Object.)
	RemoveEventHandler	Removes an event handler from an event source.
	ToString	Returns a string that represents the current object. (Inherited from Object.)

	Name	Description
	GetCustomAttribute(Type)	Overloaded. Retrieves a custom attribute of a specified type that is applied to a specified member. (Defined by CustomAttributeExtensions.)
	GetCustomAttribute(Type, Boolean)	Overloaded. Retrieves a custom attribute of a specified type that is applied to a specified member, and optionally inspects the ancestors of that member. (Defined by CustomAttributeExtensions.)
	GetCustomAttribute<T>()	Overloaded. Retrieves a custom attribute of a specified type that is applied to a specified member. (Defined by CustomAttributeExtensions.)
	GetCustomAttribute<T>(Boolean)	Overloaded. Retrieves a custom attribute of a specified type that is applied to a specified member, and optionally inspects the ancestors of that member. (Defined by CustomAttributeExtensions.)
	GetCustomAttributes()	Overloaded. Retrieves a collection of custom attributes that are applied to a specified member. (Defined by CustomAttributeExtensions.)
	GetCustomAttributes(Type)	Overloaded. Retrieves a collection of custom attributes of a specified type that are applied to a specified member. (Defined by CustomAttributeExtensions.)
	GetCustomAttributes<T>()	Overloaded. Retrieves a collection of custom attributes of a specified type that are applied to a specified member. (Defined by CustomAttributeExtensions.)
	GetCustomAttributes<T>(Boolean)	Overloaded. Retrieves a collection of custom attributes of a specified type that are applied to a specified member, and optionally inspects the ancestors of that member. (Defined by CustomAttributeExtensions.)
	IsDefined	Indicates whether custom attributes of a specified type are applied to a specified member. (Defined by CustomAttributeExtensions.)

Remarks

Use the EventInfo class to inspect events and to hook up event handlers, as shown in the example code for the AddEventHandler method.

Note:
EventInfo is not intended to be used to raise events. An object raises events as dictated by its internal state.

Calling ICustomAttributeProvider::GetCustomAttributes on EventInfo when the inherit parameter of GetCustomAttributes is true does not walk the type hierarchy. You can use System::Attribute to walk the type hierarchy for custom attributes, but only if all the attributes derive from System::Attribute.
