C# Programming/Keywords/add

< C Sharp Programming < Keywords

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 and 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.
