==Introduction to C#==

C#, known as 'C sharp' is a a computer programming language developed by Microsoft Corporation, USA. It is fully object oriented language like Java, C++, Visual Basic, Cobol etc. It is a simple, efficient, type-safe language derived from the popular C and C++ languages. It is suitable for developing Web-based applications. C# is designed for building robust, reliable and durable component to handle real-world applications. C# is expected to play a major role in developing and co-operating networks of websites. C# is one of the programming languages designed for the Common Language Infrastructure. Common Language Infrastructure is open specification. It describes the executable code and runtime environment.
Recent version of C# is 4.0 developed in April 2010. We have C# 1.0 version, 1.2 version, 2.0 version, 3.0 version as well.
C# has a unified type system. A unified type system means that all types, including primitives such as integers, are subclasses of the System.Object class. For example, every type inherits a ToString() method.
C# comp[ilers are : Microsoft Visual C#,

== Basic Level ==
# '''Structure of C# program'''
#* The basic structure of C# program with an example
#* '''Example''': My first C# program - to print a line
#* How to save the program
#* Use of public keyword.
#* The main() method.
#* How to Compiling a C# program csc filename.cs
#* How to Executing a C# program filename.cs 
#'''Variables & Data Types'''
#* Defines use of keywords as identifiers like int, float etc.
#* How values are stored in variables
#**'''Example''' : int a = 10; Value stored in a is 10.
#* Variables and Data Types
#* Declaration, Initialization and Scope of variables
#**'''Example''' : variablename = value;
#* Boxing and Unboxing
#**'''Example''' : We will box i int i = 123; object o = i; 
# '''Operators and Expressions'''
#* Understanding different operators
#**Arithmatic Operators     +, -, *, /, %, ++, -- 
#**Comparison Operators     ==, !=, <>, >, <, >=, <= 
#**Logical Operators     && (AND), || (OR), ! (NOT)
#* Evaluation of expressions
#* Precedence of Arithmetic operators.
#**According to the priority
#**'''Example''' : High priority *, /, %, and Low priority +, -
#* Type Conversions- Converting numeric values to string and vice-versa.
#**'''Example''' : Converting short to an int. short a = 10; a = b; /*implicit conversion*/    Converting numeric values to string. int m = 20; string s = m.Tostring();
#* Operator Precedence and Associativity- when more than one operator is evaluated 
#'''Decision Making and Branching'''
#* if statement - used to execute a specified condition
#** Syntax : if(condition) { true statement; }
#* if-else - used to executes a single statement or a group of statements
#**Syntax : if(condition) { true statement1; } else { false statement; }
#* Nested if-elses -
#**Syntax : if(condition) { true statement1; } else { if(condition) { true statement2; } else { false statement; } }
#* switch statement - use this statement to make a decision from a number of choices
#**Syntax : switch(integer expression) { case1 : execute statement1; case2 : execute statement2; default : execute this statement; }
#* Use of ?: operator - use this statement for making two way decisions
#**Syntax : expression1 ? expression2 : expression3 
#'''Looping'''
#* for loop -used when you know in advance how many times the script should run.
#**Syntax : for(initialization; condition; increment \ decrement) { code to be executed }
#* while loop - executes a block of code while a condition is true.
#**Syntax : while(test condition) { code to be executed }
#* do-while loop - executes he body of the loop before test condition
#**Syntax : do { code to be executed } while(test condition);
#* foreach loop - enables us to iterate the elements in array
#**Syntax : foreach(type variable in expression) \*in is a keyword*\ { code to be executed }
#* Jumps in loops - skipping a part of a loop 
#'''Methods in C#'''
#* Declaring, Invoking and Nesting of Methods
#* Pass by Value & Pass by Reference
#* Method Overloading 
#'''Handling Arrays'''
#* Creating, Declaring, Initializing Arrays
#* One Dimensional Arrays & Two Dimensional Arrays
#* ArrayList Class 
#'''Manipulating Strings'''
#* Creating, Inserting & Comparing Strings
#* Arrays of Strings
