Purpose
Using this Code Provider, you can easily add the implementation of the IComparable interface to any class containing at least one field or property. This Code Provider adds the IComparable and IComparable<T> implementations along with the CompareTo methods to the class. The CompareTo method bodies are generated automatically.
Availability
Available when the caret is on a class declaration.
Usage
Place the caret on a class declaration. The class must contain at least one field or property.
Note
The blinking cursor shows the caret's position at which the Code Provider is available.

- Select Implement IComparable from the menu.
After execution, the Code Provider adds the implementation of the IComparable interface and type-specific IComparable<T> interface. It also adds the corresponding CompareTo methods with their common implementation.
