Extension methods

Monday, May 4th, 2020

Sometimes, programmers find themselves in need of adding new functionality to already existing codes, in order to improve or complete them. If the said source code is available, the task is simple – they only need to add the required functionality and recompile.… Read more

Anonymous methods

Saturday, February 1st, 2020

Remember from the lesson lambda expressions that we can declare a method locally, without a name, and use it only in one place, where we declare it. This is an example of a lambda expression:

Lambda expressions

Sunday, January 12th, 2020

In the previous lesson I was writing that we can further improve our code by using lambda expressions. A lambda expression is a convenient way of defining an anonymous (unnamed) function that can be passed around as a variable or as a parameter to a method call.… Read more

Virtual Methods

Sunday, December 8th, 2019

Virtual methods are methods that can be overridden in inheriting (derived) classes. By default, in .NET, methods are not virtual. In order to declare a method as virtual, we need to declare it using the keyword virtual, like so:

Generic methods

Friday, June 23rd, 2017

Generic methods, like generic classes, are parameterized (typified) methods, which we use when we cannot specify the type of the method’s parameters. Also like in the case of generic classes, the replacement of unknown types with specific types happens when the method is called.… Read more

Best practices when using methods and functions

Wednesday, April 19th, 2017

There are two main reasons why methods and functions are even used. First one, which I already mentioned in a few of the previous posts, is code re-usability. The second is modularization of the code, splitting of complex tasks into smaller sub-tasks, which can offer us a better overview of the entire functionality.… Read more

Methods and functions signature

Monday, April 17th, 2017

I talked in the previous lesson about methods and functions signatures, and I offered there a brief explanation on the topic. It is time to explain this new concept in more detail. At a basic level, there are only two things that are mandatory to specify a method or function signature: the parameters type and the order in which the parameters are listed.… Read more

Functions and methods overloading

Monday, April 17th, 2017

There are times when we have functions or methods that perform basically the same thing, but use different kind of parameters. So, in other words, there are cases when we have methods with the same name, but with different signatures.… Read more

Optional parameters

Sunday, April 16th, 2017

When I explained functions and methods parameters, I said that we can use them to send different values that our methods and functions can use in their calculations. You should also know that methods and functions can have optional parameters, parameters with a default value, which can be skipped when calling a method or function.… Read more

Execution workflow

Saturday, April 15th, 2017

Whenever a method executes, it takes control over execution workflow of the program. However, if in the caller method we call yet another method, the execution is transferred to this new method, until it’s code is executed, and when that finishes, the execution control is returned to the first calling method.… Read more
