Introduction to C#

Overview of C# and Console Applications

What is C#?

  • C# is a modern, object-oriented, and type-safe programming language developed by Microsoft.
  • It is part of the .NET framework, making it versatile for various types of applications.

Basics of C# Programming

Variables and Data Types

  • Variables store data to be referenced and manipulated in programs.
  • Common data types include int, string, bool, and double.

Operators

  • Arithmetic operators (+, -, *, /)
  • Comparison operators (==, !=, >, <)
  • Logical operators (&&, ||, !)

Control Structures

Decision Making

  • if, else if, else
  • switch statements

Loops

  • for: Iterates a set number of times.
  • foreach: Iterates over items in a collection.
  • while: Continues as long as a condition is true.
  • do while: Similar to while, but checks condition after the loop.

Collections in C#

Arrays

  • Fixed size, same data type collection.

Lists

  • Dynamic size, same data type collection.
  • Part of System.Collections.Generic.

Functions in C#

  • Encapsulate reusable code blocks.
  • Can return a value or be void.

Exception Handling

  • try, catch, finally blocks handle exceptions.
  • Ensures graceful handling of runtime errors.

File I/O Operations

  • Reading and writing files is essential for data management.
  • System.IO namespace provides tools for file operations.
using System.IO;

string text = File.ReadAllText("file.txt");
File.WriteAllText("output.txt", text);
