Compiler Error CS0068

'event': event in interface cannot have initializer

An event in an interface cannot have an initializer. For more information, see Interfaces.

The following sample generates CS0068:

// CS0068.cs  
  
delegate void MyDelegate();  
  
interface I  
{  
   event MyDelegate d = new MyDelegate(M.f);   // CS0068  
   // try the following line instead  
   // event MyDelegate d2;  
}  
  
class M  
{  
   event MyDelegate d = new MyDelegate(M.f);  
  
   public static void f()  
   {  
   }  
  
   public static void Main()  
   {  
   }  
}
