Basic C# and .net
- 1. Welcome
- 2. Presented by Jannatul Ferdus Trainer Web Application .NET
- 3. Outline Introduction to .C# Introduction to .NET & IDE C# console application
- 4. 1. Basic concept in C# 2. write program in C# Learning Outcome
- 5. .NET and C# .NET Platform Web-based applications can be distributed to a variety of devices and desktops C# developed specifically for .NET
- 6. Introduction to Microsoft .NET .NET initiative Introduced by Microsoft (June 2000) • Vision for embracing the Internet in software development Independence from specific language or platform • Applications developed in any .NET-compatible language • Visual Basic.NET, Visual C++.NET, C# and more • Supports portability and interoperability Architecture capable of existing on multiple platforms • Supports portability
- 7. Microsoft .NET Key components of .NET Web services • Applications used over the Internet Software reusability • Web services provide solutions for variety of companies • Cheaper than one-time solutions that can’t be reused • Single applications perform all operations for a company via various Web services • Manage taxes, bills, investments and more • Pre-packaged components using Visual Programming • (buttons, text boxes, scroll bars) • Make application development quicker and easier
- 8. Microsoft .NET Keys to interaction XML (Extreme Markup Language) and SOAP (Simple Object Access Protocol) • “Glue” that combines various Web services to form applications • XML gives meaning to data • SOAP allows communication to occur easily
- 9. Microsoft .NET Other concepts Universal data access • Eliminates need to synchronize files • Synchronization - Updating multiple copies of same file to the most recent • Data resides at one central location • Accessible by anyone with connection and proper authorization • Data formatted appropriately for display on various devices • Same document seen on PC, PDA, cell phone and other devices
- 10. .NET Framework and the Common Language Runtime .NET Framework Heart of .NET strategy • Manages and executes applications and Web services • Provides security, memory management and other programming capabilities Includes Framework Class Library (FCL) • Pre-packaged classes ready for reuse • Used by any .NET language Details contained in Common Language Specification (CLS) • Submitted to European Computer Manufacturers Association to make the framework easily converted to other platforms Executes programs by Common Language Runtime (CLR)
- 11. .NET and C# .NET platform Web-based applications can be distributed to variety of devices and desktops C# Developed specifically for .NET Enable programmers to migrate from C/C++ and Java easily Event-driven, fully OO, visual programming language Has IDE Process of rapidly creating an application using an IDE is called Rapid Application Development (RAD)
- 12. C# Language interoperability Can interact with software components written in different languages or with old packaged software written in C/C++ Can interact via internet, using industry standards (SOAP and XML) Simple Object Access Protocol - Helps to share program “chunks” over the internet Accommodates a new style of programming in which applications are created from building blocks available over internet (reusability)
- 13. C# and the .NET IDE Console applications No visual components (buttons, text boxes, etc.) Only text output Two types • MS-DOS prompt -Used in Windows 95/98/ME • Command prompt -Used in Windows 2000/NT/XP
- 14. Home work Write a program to write factorial with n numbers. Take a digit as an input and show the reversed digit as output.
