C# Tutorial Overview

Introduction

• Overview of the tutorial structure.
• Topics covered include:
  • Fundamentals of C# and .NET
  • Types: Primitive and non-primitive
  • Control flow
  • Debugging techniques
  • Best programming practices

Section 1: C# and .NET Fundamentals

• Difference between C# and .NET:
  • C# is a programming language.
  • .NET is a framework for building applications on Windows.
• Components of .NET Framework:
  • CLR (Common Language Runtime)
  • Class Library

Common Language Runtime (CLR)

• CLR is responsible for executing .NET applications.
• Translates intermediate language (IL) code into machine code (Just-In-Time compilation).
• Allows applications to run on any machine with CLR.

Section 2: Types in C#

Primitive Types

• Types: Integer, Float, Char, Boolean, etc.
• C# is case sensitive.
• Variables should be initialized before use.
• Constants are immutable values set at compile time.

Naming Conventions

• Identifiers cannot start with a number or include whitespace.
• Use meaningful names for readability.
• Common conventions: CamelCase, PascalCase, Hungarian Notation.

Primitive Types Overview

• Integral Types: Byte, Short, Int, Long.
• Real Types: Float, Double, Decimal.
• Character Type: Char.
• Boolean Type: Bool.
• Learn about type size and ranges.

Section 3: Overflowing and Scope

• Overflowing: Exceeding the limits of a data type.
  • Use checked keyword to prevent overflow.
• Scope: Defines the visibility of a variable.
  • Variables are accessible in the block they are defined.

Section 4: Operators in C#

• Types of Operators:
  • Arithmetic: +, -, *, /, %
  • Comparison: ==, !=, >, <, >=, <=
  • Logical: &&, ||, !
  • Bitwise: &, |, ^, ~
• Operator Precedence: Multiplication and division before addition and subtraction.

Section 5: Comments in C#

• Single-Line Comments: Use //
• Multi-Line Comments: Use /* comment */
• Keep comments minimal and relevant. Avoid redundancy.

Conclusion

• C# is a statically typed language, meaning types are defined at compile time.
• Next section will cover non-primitive types like classes and arrays.
