Improving Code Readability in C# with Digit Separators

-

What Are Digit Separators?

Digit separators were introduced in C# 7.0. When dealing with large numbers, digit separators help enhance the readability of your code. By using underscore (_) as a separator within groups of numbers, you can significantly improve code readability.

Why Use Digit Separators?

Consider the scenario where you need to work with the number 1000000000. Without digit separators, reading this number can be challenging. However, by using digit separators and representing the number as 1_000_000_000, it becomes much easier to read one billion.

Examples of Digit Separators

Let's explore a few examples to understand how digit separators function:

int totalPopulation = 7_900_000_000;
double distanceToMoon = 384_400.0;
long nationalDebt = 28_000_000_000_000;

As evident, adding digit separators in between groups of digits has no impact on the numerical value itself. It only improves human readability.

Conclusion

The introduction of digit separators in C# constitutes a minor yet impactful enhancement that significantly improves your code's clarity, reduces the potential for errors, and facilitates your role as a developer.

This blog is going to illustrate how to implement Entity Framework (EF) Core with SQL Server LocalDB. The Entity Framework Core enables access to data from the database. This allows developers to avoid having to write most of the data access code. And the SQL Server LocalDB works similarly to the SQL SERVER with few features. You can get the LocalDB when you install visual studio or visual studio express. You can find the .mdf and _log.ldf files in the C:/Users/{user} directory. Let see how to create a SQL Server LocalDB and implement Entity Framework Core Step 1: The first step is to add a connection. In the menu -> click Tools and select Connect to Database It will display the Add Connection window. Enter (localdb)\mssqllocaldb in the server name textbox.

This blog is going to explain what is SignalR and how to implement it in ASP.NET Core. SignalR is a real time application framework for ASP.NET Core. Using SignalR you can provide updated information without refreshing the page, for example poll results, game score, chat etc. Let's see how to achieve it in ASP.NET Core MVC. Step 1: First step I added the SignalR client library. To add a SignalR client library, Right click on the project in Solution Explorer and Add -> Client-Side Library. Select the provider as unpkg as shown in the image below. Enter the latest version of SignalR into the library. And selected signalr.js and signalr.min.js files. Finally clicked the install button to install the client library. Step 2: At this step I have created a VoteHub.cs class inside the Hubs folder(create a new folder called Hubs). This class inherits from the Hub class which is a base class of SignalR hub. The SendMessage method will be called by the connected client. ...

Using Query Strings for Request Culture and Simplifying Localization with IStringLocalizer Interface Let’s see how to implement Localization in ASP.NET Core MVC. In the first example, I am going to use the IStringLocalizer Interface in the controller to implement Localization. Additionally, when the user passes the desired language through the query string, it will display content in that language. First, let’s configure the settings in the program.cs file. builder.Services.AddLocalization(options => options.ResourcesPath = "Resources");  The AddLocalization method adds the localization service to the service container. I have added the supported cultures here. I have added two cultures: en for English and nl for Dutch. In the RequestCultureProviders , I have included QueryStringRequestCultureProvider() . This allows the system to determine the culture information from the query string. UseRequestLocalization initializes a RequestLocalizationOptions o...
