IEnumerable and IComparable

Question

give difference between IEnumerable and IComparable with real time example. T hanks And Regards.

Munesh Sharma · Answer

IEnumerable is an interface that defines one method GetEnumerator which returns an IEnumerable interface, this in turn allows readonly access to a collection. A collection that implements IEnumerable can be used with a foreach statement. Definition IEnumerable public IEnumerator GetEnumerator (); IEnumerator public object Current ; public void Reset (); public bool MoveNext (); for example go this link for IComparable go to this link

IComparable is implemented by types that you wish to give them the ability to compare themselves to other instances of the same type, when sorting for example. IComparer is implemented by a type that you wish to use as a sorting predicate when sorting a collection. This allows you to create several classes that will compare the same two instances in different ways thus creating a different sort order. Array.Sort will use each element's IComparable implementation to sort the values or it can receive an IComparer to choose the order. For more information read How to use the IComparable and IComparer interfaces in Visual C# IEnumerable is an interface that represents the ability to iterate through the collection using an iterator. For example, anything that implements IEnumerable can be iterated through using a for-each loop. Both the Array and List classes implement the interface, and so can be used in a for-each loop. It isn't a collection in itself, it just represents a behaviour that actual collections may (and usually do) have. The generic equivalent of IEnumerable ( IEnumerable ) also serves as the source of many LINQ extension methods also, as LINQ extensions usually require the ability to enumerate over collections, and anything that implements IEnumerable will have that behaviour.

both are used for different purpose.... so I think there is no comparison between these two. IEnumerable can be used by the foreach statement.IComparable objects are indeed comparable and used create comparison logic between objects. http://support.microsoft.com/kb/320727 hope this will help you.
