How to use generic abstract class as return type ?
I have something like this:
abstract class BaseClass
class Class1 : BaseClass
public static Class1 Instance = new Class1();
class Class2 : BaseClass
public static Class2 Instance = new Class2();
public BaseClass Method(int z) where T: BaseClass
That is very important that those classes cannot be instantiated since their construstors are private so we cannot do like
[code]public BaseClass Method(int z) where T: BaseClass, **new()**[/code]
The problem arises that I cannot in switch clause return those Class1.Instance because it says "cannot convert Class1 to return type BaseClass" How can I use abstract class as return type ?? I just can not work this out. Would appreciate for any assisstance here.
