public ref class EventHandlerList sealed : IDisposable

NameDescription
System_CAPS_pubmethodEventHandlerList()

NameDescription
System_CAPS_pubpropertyItem[Object^]

Gets or sets the delegate for the specified object.

NameDescription
System_CAPS_pubmethodAddHandler(Object^, Delegate^)

Adds a delegate to the list.

System_CAPS_pubmethodAddHandlers(EventHandlerList^)

Adds a list of delegates to the current list.

System_CAPS_pubmethodDispose()

Disposes the delegate list.

System_CAPS_pubmethodEquals(Object^)

Determines whether the specified object is equal to the current object.(Inherited from Object.)

System_CAPS_pubmethodGetHashCode()

Serves as the default hash function. (Inherited from Object.)

System_CAPS_pubmethodGetType()

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

System_CAPS_pubmethodRemoveHandler(Object^, Delegate^)

System_CAPS_pubmethodToString()

This class uses a linear search algorithm to find entries in the list of delegates. A linear search algorithm is inefficient when working with a large number of entries. Therefore, when you have a large list, finding entries is slow.

For an example of using an EventHandlerList, see How to: Handle Multiple Events Using Event Properties.
