EventHandlerList Class
Provides a simple list of delegates. This class cannot be inherited.
Namespace: System.ComponentModel
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.) |
| GetHashCode | Serves as a hash function for a particular type. (Inherited from Object.) |
| GetType | Gets the Type of the current instance. (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.

The HostProtectionAttribute attribute applied to this type or member has the following Resources property value: SharedState. The HostProtectionAttribute does not affect desktop applications (which are typically started by double-clicking an icon, typing a command, or entering a URL in a browser).
