Compiler Error CS0069
An event in an interface cannot have add or remove accessors
You cannot define an event's accessor functions in an interface. For more information, see Events and Interfaces.
The following sample generates CS0069:
// CS0069.cs
// compile with: /target:library
public delegate void EventHandler();
public interface a
{
event EventHandler Click { remove {} } // CS0069
event EventHandler Click2; // OK
}
