3. Array a data structure that contains several variables of the same type. One Dimensional Array Type [ ] Array_Name = new int [arraySize]; Examples int[] 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 > Examples double[ , ] hillHeight = new double[3,4]; int[ , ] hillHeight = {{1, 2, 3, 4}, {2, 3, 4, 5}, {3, 4, 5, 6}};

7. Arrays of Arrays int[][] 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}};
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 }
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).
