Explanation:
Note:
Target 1:
The role of IComparable is to provide a method of comparing two objects of a particular type. This is
necessary if you want to provide any ordering capability for your object.
Incorrect: The role of IComparer is to provide additional comparison mechanisms. For example, you may want
to provide ordering of your class on several fields or properties, ascending and descending order on the same
field, or both.
Target 2, Target 3:
Example:
// Implement IComparable CompareTo method – provide default sort order.
int IComparable.CompareTo(object obj)
{
car c=(car)obj;
return String.Compare(this.make,c.make);
}
