Keywords add
__TOC__
The add and remove keywords allow you to execute code whenever a delegate is added or removed from an event. Its usage is similar to the get get and set set keywords with properties:
public event MyDelegateType MyEvent
{
add
{
// here you can use the keyword "value" to access the delegate that is being added
...
}
remove
{
// here you can use the keyword "value" to access the delegate that is being removed
...
}
}
The code in the add block will be executed when a delegate is added to the event. Similarly, the code in the remove block will be executed when a delegate is removed from the event.
