考虑代码：
class ChildClass : BaseClass {
public void Method1() {} //some other method
}
abstract class BaseClass : IChildInterface {
public
virtual //<- If we add virtual so that this method can be overridden by ChildClass, we get StackOverflowException and DoWork() implementation in IChildInterface is never called.
void DoWork() {
//base class specific implmentation
((IChildInterface)this).DoWork(); //call into default implementation provided by IChildInterface
}
}
interface IChildInterface : IBaseInterface {
void IBaseInterface.DoWork() {
//implmentation
}
}
interface IBaseInterface {
void DoWork(); …
