In C#, there are different ways to detemine the type of an object or type itself. These include typeof, GetType and Is. We would use typeof if we are trying to determine the type of a class, interface, array, enum etc. Typeof does not accept variables as a parameter. This is specified at compile time. If we are trying to determine the type of a variable, we would use GetType. … Continue reading C# – TypeOf, GetType, Is
Abstract classes are a type of class in C# that contains a base class implementation. The abstract class is not instantiated, and are inherited by subclasses to provide a detailed implementation. Consider the example below. We have an abtract class called Vehicle in our console app. We try to create an instance of the abtract class Vehicle: using System; using System.Collections.Generic; using System.Linq; using System.Text; using System.Threading.Tasks; namespace Carl.AbstractClass { … Continue reading Abstract Classes in C#

LINQ is useful in that you could have several different data sources you are working with within Visual Studio, and LINQ provides a way to query data uniformly. Examples include SQL, Objects, ADO.NET, Entity Framework etc. Here we will go through examples of using LINQ. Firstly, to use LINQ, you add the namespace: using System.Linq; Let’s say … Continue reading Linq and Lambda in C#

When looking at delegates, we saw how to pass delegate functions as parameters. With anonymous functions, we can define the delegate and then pass an anonymous function to it. In the example below, we are creating a delegate and then creating the anonymous function code, then … Continue reading Anonymous Functions in C#
Delegates in C# hold a reference to a method. If you think about writing methods, you may generally send parameters such as objects/type variables to the method. At times, you may want to send an actual method as a parameter to another method. Delegates are like a placeholder for methods. Let’s go through an example. Let’s say we have a list of customers that are based on different cities. Customer c1 … Continue reading C# Delegates
Generics in the .NET Framwork allow you to work with generic types without having to specify a data type until the class is instantiated. Generics are useful, in that you may have a class that you don’t want to limit the functionality to a certain data type. For example, you may have a class that can compare 2 integers, or it could also compare 2 strings. Instead of creating 2 … Continue reading Generics and T in C#
