Question

Do you know a quick way to implement method(s) from an Interface to a Class. If yes, how can you do it?

Situation : I have an Interface used by over 15 concrete classes. I added a new method and I need to implement this new method in all concrete class.

Update

All my concrete class implement the interface and all the method fine. Later, I add a new method in the interface. To be able to compile, I need to implement the new method in all class. I do not want to go 1 by 1 on each class to implement the method. Is there a way, like ‘Right clicking the new method’ in the interface that will go in all concrete class and all automaticly the new method. This way I will not have to open all class?

Answer 1

Since you mentioned that you have ReSharper installed, here some way to quickly implement this:

• Use ‘Find Usages Advanced’ with ‘Implementations’ checkbox checked
• For each class use quick action ‘Implement members’

Also you can use ‘solution wide analysis‘ feature of ReSharper – it will quickly find all classes that don’t implement this new method

EDIT:

Finally I found a really quick way:

• Save method signature in clipboard.
• Position cursor on Boo in IFoo interface (notice code error – empty code block, this is intentional).
• Right click and choose Refactor->’Push Members down’
• Select needed classes in the shown dialog box and click Next.
• Restore method signature from clipboard

internal interface IFoo {     void Boo()     {     } }  class Boo:IFoo { }  class Foo: IFoo { }
