When a BlockingCollection<T> begins, these properties are false They become true only after CompleteAdding( ) is called The following program reworks the previous example so it uses CompleteAdding( ), IsCompleted, and the TryTake( ) method:

The output from this version will be similar to that of the previous version The main difference between the programs is that now Producer( ) can produce as many items as it wants It simply calls CompleteAdding( ) when it is finished Consumer( ) simply consumes items until IsCompleted is true Although the concurrent collections are somewhat specialized, being designed for concurrent programming situations, they still have much in common with the non-concurrent collections described by the preceding sections If you are working in a parallel programming environment, you will want to make use of the concurrent collections when access by multiple threads will occur

For the sake of simplicity, the foregoing examples have stored built-in types, such as int, string, or char, in a collection Of course, collections are not limited to the storage of built-in objects Quite the contrary The power of collections is that they can store any type of object, including objects of classes that you create Let s begin with an example that uses the non-generic class ArrayList to store inventory information that is encapsulated by the Inventory class:
// A simple inventory example using System; using SystemCollections; class Inventory { string name; double cost; int onhand; public Inventory(string n, double c, int h) { name = n; cost = c; onhand = h; } public override string ToString() { return StringFormat("{0,-10}Cost: {1,6:C} name, cost, onhand); } } class InventoryList { static void Main() { ArrayList inv = new ArrayList();
On hand: {2}",

Exploring the C# Library
// Add elements to the list invAdd(new Inventory("Pliers", 595, 3)); invAdd(new Inventory("Wrenches", 829, 2)); invAdd(new Inventory("Hammers", 350, 4)); invAdd(new Inventory("Drills", 1988, 8)); ConsoleWriteLine("Inventory list:"); foreach(Inventory i in inv) { ConsoleWriteLine(" " + i); } } }
The output from the program is shown here:
Inventory list: Pliers Cost: $595 Wrenches Cost: $829 Hammers Cost: $350 Drills Cost: $1988 On On On On hand: hand: hand: hand: 3 2 4 8
In the program, notice that no special actions were required to store objects of type Inventory in a collection Because all types inherit object, any type of object can be stored in any non-generic collection Thus, using a non-generic collection, it is trivially easy to store objects of classes that you create Of course, it also means the collection is not type-safe To store objects of classes that you create in a type-safe collection, you must use one of the generic collection classes For example, here is a version of the preceding program rewritten to use List<T> The output is the same as before
// Store Inventory Objects in a List<T> collection using System; using SystemCollectionsGeneric; class Inventory { string name; double cost; int onhand; public Inventory(string n, double c, int h) { name = n; cost = c; onhand = h; } public override string ToString() { return StringFormat("{0,-10}Cost: {1,6:C} name, cost, onhand); } } class TypeSafeInventoryList { static void Main() { List<Inventory> inv = new List<Inventory>();
On hand: {2}",
