Comment Inheritance for C# (actually any language)

Question

Hi All,

Suppose I have this interface

public interface IFoo
{
    ///<summary>
    /// Foo method
    ///</summary>
    void Foo();

    ///<summary>
    /// Bar method
    ///</summary>
    void Bar();

    ///<summary>
    /// Situation normal
    ///</summary>
    void Snafu();
}

And this class

public class Foo : IFoo
{
    public void Foo() { ... }
    public void Bar() { ... }
    public void Snafu() { ... }
}

Is there a way, or is there a tool that can let me automatically put in the comments of each member in a base class or interface?

Because I hate re-writing the same comments for each derived sub-class!

Answer 1

GhostDoc does exactly that. For methods which aren't inherited, it tries to create a description out of the name.

FlingThing() becomes "Flings the Thing"

Answer 2

I agree it is annoying that comments are not inherited. It would be a fairly simple add-in to create if someone had the time (i wish i did).

That said, in our code base we put XML comments on the interfaces only and add extra implementation comments to the class. This works for us as our classes are private/internal and only the interface is public. Any time we use the objects via the interfaces we have full comments display in intellisence.

GhostDoc is good start and has made the process easier to write comments. It is especially useful keeping comments up-to-date when you add/remove parameters, re-run GhostDoc and it will update the description.

Java has this, and I use it all the time. Just do:

/** * {@inheritDoc} */

And the Javadoc tool figures it out.

C# has:
