C# is a simple, modern, general-purpose, object-oriented programming language developed by Microsoft within its .NET initiative led by Anders Hejlsberg.
C# (pronounced C Sharp) is new technology that is much powerful and easy to learn. It consists of thousands of prebuilt classes and interfaces that lets programmer to write powerful code in very less time. If you are beginners then don’t worry and just start with very first lesson and do exercises regularly. I promise you to in very short time you will be able to write complex programming module without getting help of any third party resources.
To run C# code, Visual Studio is the best editor. Either you can choose console based application to run program directly or you can write program on notepad and then run them on visual studio command prompt.
The .Net framework applications are multi-platform applications. The framework has been designed in such a way that it can be used from any of the following languages: C#, C++, Visual Basic, Jscript, COBOL, etc. All these languages can access the framework as well as communicate with each other.
Integrated Development Environment (IDE) for C#
Microsoft provides the following development tools for C# programming:
Visual Studio 2010 (VS)
Visual C# 2010 Express (VCE)
Visual Web Developer
C# programming is very easy so never be bored with this language.
The using keyword is used for including the namespaces in the program. A program can include multiple using statements.
The class Keyword
The class keyword is used for declaring a class.
Variables are attributes or data members of a class, used for storing data.
Functions are set of statements that perform a specific task. The member functions of a class are declared within the class.
An identifier is a name used to identify a class, variable, function, or any other user-defined item.
Keywords are reserved words predefined to the C# compiler.
Now save this program as Chapter1.cs. You must choose All Files in save as type box.
Go to Start > All Programs > Microsoft Visual Studio 2005 or 2008 > Visual Studio Tools > Visual Studio 2005 or 2008 Command Prompt.
Set Path in command prompt where your Chapter1.cs file is saved. Here we are using D:/Csharp>
Now compile your program by following command:
Setting environment for using Microsoft Visual Studio 2008 x86 tools.
C:\Program Files\Microsoft Visual Studio 9.0\VC>d:
Microsoft <R> Visual C# 2008 Compiler version 3.5.30729.1
for Microsoft <R> .NET Framework version 3.5
