ITF11006 .NET

1. ITF11006 .NET The Basics

2. The Basics • Data Types • Value Types • Reference Types • Flow Control • Conditional • Loop • Miscellaneous • Enumerations • Namespaces • Class / Struct • Data Members • Functional Mem • Base Classes • System.Object • System.String

3. Variables/Constants • Syntax[modifier] type identifier [= expression]; • Scope • Class/Block • Constants[modifier] const type identifier [= constant-expression]; • Type Inferencevar identifier [= expression];

4. Predefined Data Types • Value Types • Reference Types

5. Predefined Data Types • Value Types • Integer Types • Floating Point Types • Decimal Type • Boolean Type • Character Type

6. Integer Types

7. Floating Point

8. Decimal Type

9. Boolean Type

10. Character Type

11. Nullable Types (http://msdn.microsoft.com/en-us/library/1t3y8s4s(v=VS.100).aspx) • T? orSystem.Nullable(Of T) • Ordinary type plus null

12. Predefined Reference Types • Object • String

13. Flow Control • Conditional • if • switch • Loop • for • while • do..while • foreach • Jump • goto • break • continue • return

14. Conditional Statements • if if (expression) statement1 [else statement2] • switchswitch (expression) { case constant-expression: statement jump-statement [default: statement jump-statement] }

15. Loops • forfor ([initializers]; [expression]; [iterators]) statement • whilewhile (expression) statement • do..whiledo statement while (expression); • foreachforeach (typeidentifier in expression) statement

16. Jump Statements • goto • break • continue • return • (throw)

17. Enumerations • enum[modifiers] enum identifier [:base-type]{enumerator-list} • Inherits from System.Enum • Flags Attribute • Use enumerations

18. Namespaces • Logical grouping of functionality • <company>.<technology/sw package> • Using directive

19. Class (/Struct) • Data Members • Fields • Constants • Events • Function Members • Methods • Properties • Constructor • Destructor • Operators • Indexers

20. Methods • syntax[modifiers] return-type method-name([formal-parameter-list]) { statement(s)} • Named Argumentsstring FullName(string firstName, string lastName)…FullName(“Ole”, “Olsen”);FullName(lastName: “Olsen”, firstName: “Ole”); • Optional Arguments • Method Overloading

21. Properties • syntax[modifiers] type identifier{ set {accessor-body} get {accessor-body} } • Auto-Implementedpublic string Age(get; private set;) • Choosing Between Properties and Methods http://msdn.microsoft.com/en-us/library/ms229054.aspx

22. Construction and Disposal • Constructors • Instance • Class • Calling • Destructor • Why • How (pattern) • Dispose vs. Close

23. Operators • Operator Overloading public static Vector operator * (double lhs, Vector rhs) { return new Vector(lhs * rhs.x, lhs * rhs.y, lhs * rhs.z); } public static Vector operator * (Vector lhs, double rhs) { return rhs * lhs; } Console.WriteLine("vect2 * 2 = " + ( vect2 * 2).ToString());

24. Indexers public char this[int index] { get { ... } set { ... } }

25. Instance vs. Class Level • Static • this vs. class name

26. Struct • No inheritance (almost) • Constructors • Fields are sometimes declared public! • Structs are value types

27. Struct vs. class • Footprint • Performance

28. object (System.Object) • Methods • Comparing for Equality • Reference Types • Value Types
