If you want to sort objects that are stored in a non-generic collection, then you will implement 

the non-generic version of 

IComparable

. This version defines only one method, 



CompareTo( )

,

which determines how comparisons are performed. The general form of 



CompareTo( )

 is 


shown here:

int CompareTo(object
