Background In C#, programmer has no control on when the destructor is going to be executed because this is determined by the Garbage Collector. The garbage collector checks for objects that are no longer used by the application and calls the destructors of all the objects and reclaims the memory...
Background As in other langauges When you derive a class from a base class, the derived class will inherit all members of the base class except constructors, though whether the derived class would be able to access those members would depend upon the accessibility of those members in the base...
In my old MFC programming days we used to track the problems using the OutputDebugString and I have written my own version of OutputDebugString which accepts multiple arguments. When I started C# and .NET I wanted to know how can I do this in C sharp as well and remember that it should be as simple...
System.Windows.Forms.Timer 1. It's a forms-based timer. 2. After creating it, you can set the interval which elapses between ticks using the Interval and hook up a delegate to its Tick event. 3. Calling Start and Stop methods, start and stop of the timer. 4. It runs entirely on the...
Introduction Whenever you generate a new C# Windows Application using the .NET IDE you have the following lines in the main of your program in program.cs file. Did you ever try to note what are these and what do they do. If not I will explain to you the meaning of each line. ...
Introduction Iteration Statements are often known as looping, and they run many times while specific condition is true. I would try to explain some of them here. The lesson is for a begginer, and I guess that everyone need to know them. While The While loop function used and while the...
Introduction Classe Will be used to implement most objects. Somtimes however, it may be desirable to create an object that behavves like one of the references. in that case, a value type used, wich is done by declaring a Struct in C#. structs act similarly to classes, but with a few added...
Introduction LinkedList is a general-purpose linked list. It supports enumerators and implements the ICollection interface.It is a true linked list with separate nodes of type LinkedListNode, so insertion and removal are O(1) operations. Lists that contain reference types perform better if...
Introduction An event is a message sent by an object to signal the occurrence of an action. The action could be caused by user interaction, such as a mouse click, or it could be triggered by some other program logic. The object that raises the event is called the event sender. The object that...

C# is an object-oriented programming language developed by Microsoft Corporation . C# source code as well as those of other .NET languages is compiled into an intermediate byte code called Microsoft Intermediate Langauge. C# is primarily derived from the C, C++, and Java programming languages with...
Introduction Exceptions are unforeseen errors that happen in your programs. Most of the time, you can, and should, detect and handle program errors in your code. For example, validating user input, checking for null objects, and verifying the values returned from methods are what you expect, are...
Class overview Microsoft documentation says the Directory class exposes static methods for creating, moving, and enumerating through directories and subdirectories. In addition, you may access and manipulate various directory attributes such as creation or last modified time stamps, along...
When Windows developers need a unique value, they often utilize a Globally Unique Identifier (GUID). Microsoft uses the term GUID for a unique number that identifies an entity, such as a Word document. A GUID is a 128-bit integer (16 bytes) that you can use across all computers and networks...
Introduction Before designing a class, we should have a very clear understanding about constructor. In this article I will discuss definition, types and features of constructor. Definition A constructor looks like a special method having no return type and its name is same with the class...
C# and Java are object oriented language where all code resides in a .NET type called class. An object oriented languages are those languages where user defined code has to be in some class. C# is 99.9% object oriented. You must be wondering why not 100%? The reason is that primitive data types in...
In the articles on namespaces in C#, I explained in detail that .NET framework class library contains thousands of classes, interfaces and enumeration in hundreds of assemblies. These classes are related to each other. We also know that C# is a purely object oriented language. Object oriented...
Any software application, two of the most frequently done tasks are formatting and parsing the data. In simplest words, formatting refers to the process of converting some type to string and conversely parsing refers to converting string into some other data type. There are several techniques that...
In addition to string, another extremely important entity that lays at the foundation of any software application is the numbers. Numbers play a very crucial role, particularly in the business logic layer of any software application. Logic building requires strong knowledge of numbers and their...
In my last article, Complete Threading Tutorial in C#, I explained basics of threading. I explained that how threads can be created, how locking is implemented to make your applications thread-safe and how exception handling is implemented in threaded applications. This article explains some more...
