This is a C# presentation.... presented by me.....

2. What is a C#?
 C# (pronounced "C-sharp") is an object-oriented
programming language from Microsoft.
 That aims to combine the computing power
of C++ with the programming ease of Visual Basic.
 C# is based on C++ and contains features similar to
those of Java.

Categories of develop
 C# is used to develop two main categories of programs
namely,
 Executable application programs and
 Component libraries

6. C# COMPONENTS
C# contains many different components, including:
 Versioning support, so that the base and derived classes-
templates that define how an object performs and it remain
compatible as we develop them.
 Events, so that the program can notify clients of a class
about something that has happened to an object.
 Type safety and verification that increases reliability and
ensures code security.
 Garbage collection, so that the program can identify
objects that program can no longer reach.
 Unsafe mode, where it can use pointers to manipulate
memory outside the garbage collector’s control, including
methods and properties.

7. Windows application in C#
• Design environment:
Solution explorer
Menus
Form
Code editor
Toolbar
Properties/events
messages window

8. Difference between Windows &
Console application in C#
Windows application Console application
 The windows application has  But the console application is
the design time form not having any design time
 It is like VB due to the form
presence of the design time  It is like C or C++ due to the
form absence of the design time
 The output will be displayed form
in the Run time form as like  The output will be displayed
VB in the Command Prompt

9. Sample program
Class name
Field
Method
Method body
Static Method
Local variable
Method parameters
Method invocation

10. CLASS:
 A class is a template that defines the form of an object.
Fields:
 A fields (i.e) which are objects or values contained in
a class or structure.
Methods:
 A method is a code block containing a series of statements.
 In C#, every executed instruction is done so in the context
of a method.
Method parameters:
 The Method Parameters are nothing but they simply allow
information to be passed into and out of a method.

11. Method Invocation:
 Method Invocation is nothing but calling the calling
the method for another time.
Local variable:
 A local variable is a type of variable that can be used
where the scope and extent of the variable is within
the method or statement block in which it is declared.
Static method:
 Static methods have no instances. They are called
with the type name.
 They are slightly faster than instance methods because
of this, Static methods can be public or private.

12. APPLICATIONS OF C#
 This Visual C# was used for variety of application that
are supported by the .Net plat forms, such as
 It is used for developing Console applications and
Windows applications.
 It is used for developing Windows controls
 It is used for developing ASP.NET projects
 It is used for developing web controls
 It is used for providing web services
 It is used for developing .NET component library

13. Major Highlights of C#
 It is the Brand new language derived from C/C++
family.
 It is the First Compound Oriented
Programming(COP) Language.
 It Simplifies & modernizes the C++.
 It is the only COP language available today.
 It is the only language designed for the .Net frame
work.
