I often find myself needing for an interface (e.g. when I want to keep my type convertible, compared, etc.) but unfortunately unaware of them (I'm not a big .NET developer.), so I'm not always coming up with familiar signatures.

So, I think that there are probably a lot more like me and it could be nice to have a list of the common interfaces, so whenever I'd make a type I could look if there's something I need.

So, I'll start (for the sake of others) and I hope you could inform us of more interesting (and common) interfaces.

• IList<T>
  
• ICollection<T>
  
• IEnumerable<T>
  
• IComparable<T>
  
• IDisposable
  
• IConvertible
  
• IComparer<T>

(Note that the name of the interface and the <T> afterwards consist of 2 different links)

I used to use IComparable<T> a lot, but now I'm using IComparer<T> more.

Thank you!
I didn't quite get their purpose and differences, care to enlighten me?

Why not just be a bit curious and find out yourself. Hint: Used when comparing objects.

If you play with WPF or Silverlight a lot, INotifyPropertyChanged is something that you should be familiar with.

If you find yourself needing an interface and you can't find an existing one that matches your need don't forget you can always create your own interface.

[AdamSpeight2008]

And if you decide to define your own interface you can inherit multiple interfaces.
