Can I add a helper overload to a collection?

Question

0.00/5 (No votes)

See more:

I've defined a class like this:

C#

class TextEnhancement
...
public TextEnhancement(int offset, int length)
{
   ...
}

And then I've defined a collection that uses this type as:

C#

public List<TextEnhancement> mTextEnhancements;

Normally I'd then add an element to this collection thus:

C#

mTextEnhancements.Add(new TextEnhancement(offset: 6, length: 5));

However, is it possible to also provide some helper overload that would allow me to add an element to this collection as follows?

C#

mTextEnhancements.Add(offset: 6, length 5);

Thanks.

What I have tried:

I'm totally baffled about this so I'm still confused. This is why I've turned to the C# gurus on this site to see if this can be done.

Create your own collection type, inheriting from Collection<t>:

C#

public class TextEnhancementCollection<TextCollection>
{
    public void Add(int offset, int length)
    {
        Add(new TextEnhancement(offset, length);
    }
}

Create your collection instead of using List<t>:

C#

TextEnhancementCollection myCollection = new TextEnhancementCollection();
myCollection.Add(6, 5);
