Compiler Error CS1609

Modifiers cannot be placed on event accessor declarations

Modifiers can only be placed on event declarations and not on the event accessor declarations. For more information, see Using Properties.

Example

The following sample generates CS1609.

// CS1609.cs  
// compile with: /target:library  
delegate int Del();  
class A  
{  
   public event Del MyEvent
   {  
      private add {}   // CS1609  
      // try the following line instead  
      // add {}  
      remove {}  
   }  
}
