Compiler Error CS0074
'event': abstract event cannot have initializer
If an event is marked as abstract, it cannot be initialized. For more information, see Events (C# Programming Guide).
The following sample generates CS0074:
// CS0074.cs
delegate void D();
abstract class Test
{
public abstract event D e = null; // CS0074
// try the following line instead
// public abstract event D e;
public static void Main()
{
}
}
