The following table shows the differences between the IComparer and IEqualityComparer interfaces:

IComparer	IEqualityComparer
The IComparer interface provides a method that compares two objects.	The IEqualityComparer interface provides a method to support the comparison of objects for equality.
It provides a method named Compare() that compares two objects and returns a value indicating whether one is less than, equal to, or greater than the other.	It provides two methods, namely Equal() and GetHashCode(). Equal() checks two objects for equality, whereas GetHashCode() returns a hash code for the specified object.
int Compare(Object x, Object y) { } int CompareTo(Object x) { }	int Equals(Object obj1, Object obj2) { } int GetHashCode(Object obj) { }
