Visual Studio: How do I show all classes inherited from a base class?
For VS2012,
- Navigate to file in solution explorer
- Expand and select your class
- Right click the class item (not the file item) -> Derived Types
Sure, Resharper can do this. And much more.
Just right click on type name in any place and choose "Go To Inheritor" in context menu. "Go To Inheritor" can be also applied to method for navigating to overrides and an interface method's implementations. For an interface you could call "Find Usages Advanced" again, just right click) where to find all extendings and implementations. For a type - derived types. And my favorite feature - click with holding Control on any type/method for navigating to its declaration.
I think it's a must-have tool for .net developers.
In Resharper 9.2, on any type in source code, rt-click "Find Usage Advanced", select Find="Derived" and Scope="Solutions and Libraries".
For example, to find all inheritors (both in the library and your code) of some base class in an included DLL from any vendor, declare a variable in your code with that base class. Then right-click on that base class name you just typed.
You don't necessarily need Reflector for this - Visual Studio's "Class Diagram" view will let you easily find all derived classes for a particular class as well. Right click on the class in "Class View" and choose "View Class Diagram". If the diagram doesn't show the level of detail you want for the hierarchy, right click on the box for the class in the diagram, and choose "Show Derived Classes".
Might not be as direct as ReSharper, but it's an option if you don't have R# already.
Unfortunately, I'm not certain which particular versions of Visual Studio have it.
