Properties in C#: New cover on old book by Vivek Gupta

Namespaces

Properties are accessor methods whose job it is to retrieve and set the values of
fields.

Exceptions in C# provide a structured, and type-safe way of handling both system
level and application level error conditions. The exception mechanism in C# is very
similar to that of C++

What & Why? Properties: Part 1 by Rahul Sharma
If you were programming in C or C++ before coming to C#, you'll be a little bit
confused about properties.

In the part 1 of this series, I discussed about the get method of the properties, with
the help of which you can make your variable so that nobody can modify the value of
the variable

Understanding and Implementing Namepsaces in C# by G. Gnana
Arun Ganesh
Namespaces allow you to create a system to organize your code. A good way to
organize your namespaces is via a hierarchical system.

Operator Overloading in C# by Prasad H.
The Source code below shows how to use OperatorOverloading in C#. Operator
Overloading is pretty useful concept derived from C++ by C#.

Using Attributes in C# by Rajadurai P.
This article shows how to create custom attribute classes, use them in code, and
query them.

Using Array class and IEnumeration by Rajadurai P.
This article illustrates the usage of Array class and IEnumerator. Array class Provides
methods for creating, manipulating, searching and sorting arrays, thereby serving as
the base class for all arrays in the common language runtime.

Enumerators in C# by Prasad H.
Sample example shows you how to use enumerators in C#.

Visual Inheritance in C# by Prasad H.
Mindcracker

We all know that Inheritance means a extending a class with more Features without
worrying about the implementation of features of hidden inside the class to be
inherited.

Visual Inheritance Part 2 by Prasad H.

Abstract Classes and Methods by Rajesh V.S.
This is a detailed analysis of Abstract classes and methods in C# with some concrete
examples.

Constructors and Destructors by Rajesh V.S.
This detailed article talks about how constructors and destructors work in C# and
how to use them in your applications.

Encapsulation in C# G. G. Arun Ganesh
In Object Oriented programming Encapsulation is the first pace. Encapsulation is the
procedure of covering up of data and functions into a single unit (called class).

Method Parameters in C# G. G. Arun Ganesh
This article describes different method parameters such as value parameters,
reference parameters, output parameters, and parameter arrays.

Understanding Properties in C# Rajesh V.S.
In C#, properties are nothing but natural extension of data fields. They are usually

known as ‘smart fields’ in C# community.

Understanding Structures in C# Rajesh V.S.
A structure in C# is simply a composite data type consisting of a number elements of
other types.

Understanding Enumerators in C# Rajesh V.S.
An enumeration (enum) is a special form of value type, which inherits from
System.Enum and supplies alternate names for the values of an underlying primitive
type.

Inheritance and Polymorphism

Rajesh V. S.

By using the concept of inheritance, it is possible to create a new class from an
existing one and add new features to it.

Exploring Delegates

By Filip Bulovic

Delegates are a kind of type safe function pointers which are actually declared as
class derived from System.MulticastDelegate.

BitWise Operations in C#

By Chandra Hundigam

C# has lots of flexibility over manipulating with bits. Before I start explaining about

bit wise manipulation I would like to give some inputs on binary operations.

Pointers in C#

Rajesh V. S.

C# also supports pointers in a limited extent. A pointer is nothing but a variable that
holds the memory address of another type. But in C# pointer can only be declared to
hold the memory address of value types and arrays.

Implementing Stacks in C#

Danish Sami

With the help of C# we can also implement ADT (Abstract Data Types) with little
effort. An example of ADT is a simple stack of integers.

Working with Namespaces in C#

Rajesh V. S.

In C#, namespaces are used to logically arrange classes, structs, interfaces, enums
and delegates. The namespaces in C# can be nested. That means one namespace
can contain other namespaces also.

Passing const parameters in C#, C++, and VB.NET by Bulent Ozkir

Parameter passing to a function is extremely important in all programming languages.
The desire to keep the passed parameter intact forced the compiler designers to add
various keywords to

Multiple inheritance in C# by Craig Breakspear
Can you inherit from multiple classes in C#? Simply put, this cannot be done. However
there are ways around it. From a design perspective you must ask yourself, Will a
Class fully represent an object?

Interface Component Interoperability by G. Gnana Arun Ganesh
The fundamental concept behind both COM and DCOM is the interface. An interface is
an agreement between a client and an object about how they will communicate with
each other.

C# Language changes from .NET Beta 1 to .NET Beta 2
This article contains C# language changes from Beta 1 to Beta 2. Submitted by Vivek
Gupta. Source MSDN documentation.

Using out and ref parameters By Kunal Cheda
When we pass a parameter as ref to a method, the method refers to the same variable
and changes made will affect the actual variable.

The out and ref parameters
The out and the ref parameters are used to return values in the same variables, that
you pass an an argument of a method. These both parameters are very useful when
your method needs to return more than one values.

Serializing Objects in C#
In simple words serialization is a process of storing the object instance to a disk file.
Serialization stores state of the objecti.e. member variable values to disk.
Deserialization is reverse of serialization i.e.

operators are overloaded and can be used in a easy manner.

This part of tutorial explains about C# and how to write and compile your first C# program from
command line.
What is C#?
C# is a new programming language developed by Microsoft. C# has power of C++ since it's
derived from C and C++. It is simpler as VB. Besides that, C# is a Java like language for web
programming and it has some good features of Delphi too. Microsoft says, that C# is the best
language to develop its .NET Framework applications.

Installing .NET SDK
Installing .NET SDK is first step to run C# on your machine. You can install .NET SDK on Windows
ME, Windows NT, or Windows 2000. But Windows 2000 is recommended. After selecting your OS,
you need to follow these steps:

Install IE 5.5
Install Microsoft .NET Framework SDK. It's free and you can download it here. NET
Framework SDK.
After installing these you can write your code in any text editor and save it as .cs
extension. Type this in an notepad and save as my.cs.

C# Compiler and Editors
.NET SDK Beta 1 release of Microsoft's new platform, .NET, incorporated with C# command line
compiler. You must have to install .NET SDK to run a C# program. Once you install .NET SDK,
you can write your C# program in any text editor including notepad, wordpad or Visual Studio.
There are some third party editors are available in the market too. Some of them are free. Check
out tools section of C# Corner.
Write your first C# program
Writing your first C# program is similar to writing C++ applications. You open any text editor, I
described in the above paragraph and type this code.
using System;
class MyClass
{
static void Main() {
Console.WriteLine("Hello World!");
}
}

Compile your first C# program
Now use command line to compile your cs file. C# compiler takes at least one argument i.e., file
name. Say your C# file name is myclass.cs then here is command line syntax.

csc myclass.cs

C# compiler creates an exe file in the bin dir of your project. Just run this exe
and see the output.
