OOP in C#
- 2. Agenda
- 3. Arraya data structure that contains several variables of the same type. One Dimensional ArrayType [ ] Array_Name = new int [arraySize]; Examplesint[] myIntArray = {5, 9, 10, 2, 99}; int[] myIntArray = new int[5]; int[] myIntArray = new int[5] {5, 9, 10, 2, 99};
- 5. Multidimensional Arrays -A two - dimensional array such as this is declared as follows: < baseType > [ , ] < name > Examplesdouble[ , ] hillHeight = new double[3,4]; int[ , ] hillHeight = {{1, 2, 3, 4}, {2, 3, 4, 5}, {3, 4, 5, 6}};
- 7. Arrays of Arraysint[][] MyArray; MyArray = {{1, 2, 3}, {1}, {1, 2}}; int[][] MyArray = {new int[] {1, 2, 3}, new int[] {1}, new int[]{1,2}}; MyArray = new int[2][];MyArray[0] = new int[3];MyArray[1] = new int[4]; MyArray= new int[3][] {new int[] {1, 2, 3}, new int[] {1},new int[] {1, 2}};
- 10. String Builder
- 11. Array List
- 12. Queue
- 14. Functionsstatic Void < functionName > ( ){ ... } static < returnType > < functionName > ( ) { ... return < returnValue > }
- 18. Value Parameters
- 20. Out Parameters
- 21. Main Function static void Main( )static void Main(string[] args)static int Main()static StringMain(string[] args)
- 24. Struct Function
- 25. Overloading Functions create multiple functions with the same name, but each working with different parameter types
- 26. Generic
- 27. Delegates A delegate is a type that enables you to store references to functions.
- 29. try . . . catch . . . finally try { //the code that might has exception } catch { //exception handling block } finally { //this block is executed either there is exceptions or not }
- 32. Constructors
- 33. This
- 34. Access Modifier-Public Members are accessible from any code.-Private Members are accessible only from code that is part of the class (the default if no keyword is used). -Protected Members are accessible only from code that is part of either the class or a derived class.-Internal Members are accessible only from code within the project (assembly) where they are defined. -Protected Internal These are only accessible from code - derived classes within the project (more accurately, the assembly).
- 35. Class Definition
- 39. Encapsulation
- 41. Inheritanceis -a
- 42. has -a
- 43. tire is a carcar has a tirehas -a
- 46. Interface-like a class, but has no implementation.-Can be Internal or Public
- 50. Polymorphism
- 51. Future Sessions
- 52. Q & AThanks
