EventHandlerList Class
Provides a simple list of delegates. This class cannot be inherited.
Assembly: System (in System.dll)
The EventHandlerList type exposes the following members.
| Name | Description | |
|---|---|---|
![]() ![]() | AddHandler | Adds a delegate to the list. |
![]() ![]() | AddHandlers | Adds a list of delegates to the current list. |
![]() ![]() | Dispose | Disposes the delegate list. |
![]() ![]() | Equals(Object) | Determines whether the specified Object is equal to the current Object. (Inherited from Object.) |
![]() ![]() | Finalize | Allows an object to try to free resources and perform other cleanup operations before it is reclaimed by garbage collection. (Inherited from Object.) |
![]() ![]() | GetHashCode | Serves as a hash function for a particular type. (Inherited from Object.) |
![]() ![]() | GetType | Gets the Type of the current instance. (Inherited from Object.) |
![]() ![]() | MemberwiseClone | Creates a shallow copy of the current Object. (Inherited from Object.) |
![]() ![]() | RemoveHandler | Removes a delegate from the list. |
![]() ![]() | ToString | Returns a string that represents the current object. (Inherited from Object.) |
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.
