目标C的协议代表等同于xamarin(Protocol delegates of Objective C equivalent in xamarin)

 我想使用委托设计模式将一些任务分配给子对象，一旦完成它必须让我知道，以便我可以采取相应的行动。 
 
 但是在Objective c中，可以使用Protocols轻松完成。 
 
 我知道Protocol等价是C＃中的接口，但我找不到任何关于如何在c＃中进行委托的例子我知道我们必须将子对象声明为弱，否则将发生循环引用。 
 
 如果有任何其他替代方法可以实现这一目的，那么在c＃中不可能进行AFAIK授权 
 
 使用代码片段进行解释将是一个好主意 

I would like to use delegation design pattern to assign some tasks to child object and once its done it has to let me know so that I can act accordingly.
 
But in Objective c it can be done easily using Protocols.
 
I know Protocol equivalent is interface in C# but I couldn't find any examples on how to proceed delegation in c# I know we have to declare child object as weak or else cyclic reference will occur.
 
AFAIK delegation is not possible in c# if there are any other alternatives to achieve this thing
 
Explaining with a code snippet would be a good idea
