Difference between IComparable and IComparer Interface in C#
IComparable Interface in C#
Use the IComparable Interface in C# to sort elements. It is also used to compare the current instance with another object of same type.
It provides you with a method of comparing two objects of a particular type. Remember, while implementing the IComparable interface, CompareTo() method should also be implemented.
Let us see an example −
int IComparable.CompareTo(object ob) {
Vehicle v=(Vehicle)ob;
return String.Compare(this.make,v.make);
}IComparer interface in C#
The IComparer interface is used to sort elements that compare two objects and provides additional comparison method.
Example
private class sortYearAscendingHelper : IComparer {
int IComparer.Compare(object ob1, object ob2) {
Vehicle v1=(Vehicle)ob1;
Vehicle v2=(Vehicle)ob2;
if (v1.year > v2.year)
return 1;
if (v1.year < v2.year)
return -1;
else
return 0;
}
}Now return an instance of IComparer object.
public static IComparer sortYearAscending() {
return (IComparer) new sortYearAscendingHelper();
}
