What are the collection classes?

What are the collection classes?

The .NET Framework provides specialized classes for data storage
and retrieval.
These classes provide support for stacks, queues, lists, and hash tables. (More...)

Which of the following statements are correct about the Collection Classes available in Framework Class Library?

A.Elements of a collection cannot be transmitted over a network.
B.Elements stored in a collection can be retrieved but cannot be modified.
C.It is not easy to adopt the existing Collection classes for newtype of objects.
D.Elements stored in a collection can be modified only if allelements are of similar types.
E.They use efficient algorithms to manage the collection, thereby improving the performance of the program.

Answer: Option E (More...)

What is Garbage Collection in .Net? Garbage collection process?

The process of transitively tracing through all pointers to actively used objects in order to locate all objects that can be referenced, and then arranging to reuse any heap memory that was not found during this trace. The common language runtime garbage collector also compacts the memory that is in use to reduce the working space needed for the heap. (More...)

What is the difference between Finalize and Dispose (Garbage collection)

Class instances often encapsulate control over resources that are not managed by the runtime, such as window handles (HWND), database connections, and so on. Therefore, you should provide both an explicit and an implicit way to free those resources. Provide implicit control by implementing the protected Finalize Method on an object (destructor syntax in C# and the Managed Extensions for C++). The garbage collector calls this method at some point after there are no longer any valid references to the object.
In some cases, you might want to provide programmers using an object with the ability to explicitly release these external resources before the garbage collector frees the object. If an external resource is scarce or expensive, better performance can be achieved if the programmer explicitly releases resources when they are no longer being used. To provide explicit control, implement the Dispose method provided by the IDisposable Interface. The consumer of the object should call this method when it is done using the object. Dispose can be called even if other references to the object are alive.

Note that even when you provide explicit control by way of Dispose, you should provide implicit cleanup using the Finalize method. Finalize provides a backup to prevent resources from permanently leaking if the programmer fails to call Dispose. (More...)

What are Abstract base classes?

Abstact Class is nothing but a true virtual class..
This class cannot be instantiated instead it has to be inherited.
The method in abstract class are virtual and hence they can be overriden in the child class. (More...)

What is garbage collection in dotnet?

Garbage collection is a mechanism that allows the computer to detect when an object can no longer be accessed. It then automatically releases the memory used by that object (as well as calling a clean-up routine, called a "finalizer," which is written by the user). Some garbage collectors, like the one used by .NET, compact memory and therefore decrease your program's working set. (More...)

What is garbage collection?

Garbage collection is a CLR feature which automatically manages memory. Programmers forget to release the objects while coding..... Laziness (Remember in VB6 where one of the good practices is to set object to nothing). CLR automatically releases objects when they are no longer in use and refernced. CLR runs on non-deterministic to see the unused objects and cleans them. One side effect of this non-deterministic feature is that we cannot assume an object is destroyed when it goes out of the scope of a function. Therefore, we should not put code into a class destructor to release resources. (More...)

Does C# support friend classes like in C++?

No. About the closest you can come is using the internal keyword, which allows access within the current assembly. But, there is no way to specify specific a class that knows about another class's private implementation. (More...)

Give Some Examples of Generic Classes?

List,Queue,Stack,LinkedList,HashSet (More...)
