IComparable has a method named as CompareTo & has only 1 parameter. Because it compares the current object with the next object which is coming as a parameter. Hence current object CompareTo next object. But IComparer has 2 parameters because we are going to pass both of the objects as arguments.
How does list sort Work C#?
