Method Overloading is basically a technique that lets you have different versions of the same method, where each version of the method does a different thing. It essentially makes methods more versatile. Each version of the method accepts different/types of input parameters. The way you control which of version method […]

In the previous unit we came across: [csharp] using System; using System.Collections.Generic; using System.Linq; using System.Text; using System.Threading.Tasks; namespace InheritenceInAction { class Program { static void Main(string[] args) { // Here we create an object using the orange class Orange AnOrange = new Orange(1.25, 45, "Spain", "25-01-2015", "sweet", true, "clementine"); […]

A variable is essentially a container that’s used for storing data. This container has a name assigned to it. In programming, this name is used to refer to the variable’s content. In c# there are actually three high-level types of variables: Value Types Reference types Pointer types (we will ignore […]

Child classes can inherit methods from it’s parent class, in the same way that it inherits properties. Here is an example of the Orange class inheriting the “SomeInfo” method, which have been originally defined in the Item class:   [csharp] using System; using System.Collections.Generic; using System.Linq; using System.Text; using System.Threading.Tasks; […]

Previously we looked at why variables are categorized as either “value types”, or “reference types” (primarily for memory reasons). Now lets take a look at these variables in action, starting with the string variable. String variables We already encountered string variables when we created the “message” string variable in our […]

Here’s a quick a simple class for creating a a series of random numbers, by creating an instance of the “Random” class, and applying this class’s next() method: http://msdn.microsoft.com/en-us/library/system.random%28v=vs.110%29.aspx Here is the code: [csharp] using System; using System.Collections.Generic; using System.Linq; using System.Text; using System.Threading.Tasks; namespace RandomNumberGenerator { class Program { […]

C# is a object oriented language, and that means that whenever we declare a new variable, we are actually using a class that generates (aka instantiates) that variable for us. Let’s says that somewhere in our program we have the following statement: int MyFavouriteNumber = 7 ; Here we are […]

Here are some terminologies: Arrays: This is a object variable, that is designed to store a collection of object-variable. Each object variable is stored in numbered containers (i.e. they are indexed), with the first container starting at number 0. Generics: these are like arrays, but they can only store builtin […]

As mentioned earlier, a method is a block of code that performs a specific task. Methods can require some information in order for it to run. This info has to be provided in the form of an “input parameter” Methods can also output information after it has completed running. This […]

Arrays are used to store a a group of items as a collection: [csharp] using System; using System.Collections.Generic; using System.Linq; using System.Text; using System.Threading.Tasks; namespace Arrays { class Program { static void Main(string[] args) { // Here we are creating an array called "vowels", that can house up to 5 […]
