hi friend Collections are just like arrays you can store more than one elements in one variable entity... The main Difference is the collections are Dynamic. means Dynamically CRUD operations can be performed and .net framework have provided properties and methods to manipulate the collections. The above post is the Listing of available collections with their namespaces.. you can use collections according to your requirements like different types of Types can be stored in ArrayList and if you want to make them bound to specific Type then use Generics like List .. And moreover you can use Dictionaries like HashTables and SortedLists where each value stored is associated with a key... So Get the Sharp Edge of C-Sharp ....Enjoy Coding..... :)

-->The .NET Framework has powerful support for Collections. Collections are enumerable data structures that can be assessed using indexes or keys. The System.Collections namespace The System.Collections namespace provides a lot of classes methods and properties to interact with the varying data structures that are supported by it. The interfaces that are defined in this namespace include: · IEnumerable · IEnumerator · ICollection · IList · IDictionary The following are the classes that are derived from the ICollection interface. · System.Collections.Stack · System.Collections.Queue · System.Collections.BitArray · System.Collections.Specialized.NameValueCollection The IDictionary interface represents collections that have name value pairs. The collections that inherit the IDictionary interface include: · System.Collections.SortedList · System.Collections.Hashtable · System.Collections.Specialized.HybridDictionary · System.Collections.Specialized.ListDictionary The IList interface represents collections that only have value. The following are the classes that extend this interface. · System.Array · System.Collections.ArrayList · System.Collections.Specialized.StringCollection Show use of collection with examples USe of collection
