Overview of this book

C# is a powerful, versatile language that can unlock a variety of career paths. But, as with any programming language, learning C# can be a challenging process. With a wide range of different resources available, it’s difficult to know where to start. That's where The C# Workshop comes in. Written and reviewed by industry experts, it provides a fast-paced, supportive learning experience that will quickly get you writing C# code and building applications. Unlike other software development books that focus on dry, technical explanations of the underlying theory, this Workshop cuts through the noise and uses engaging examples to help you understand how each concept is applied in the real world. As you work through the book, you'll tackle realistic exercises that simulate the type of problems that software developers work on every day. These mini-projects include building a random-number guessing game, using the publisher-subscriber model to design a web file downloader, creating a to-do list using Razor Pages, generating images from the Fibonacci sequence using async/await tasks, and developing a temperature unit conversion app which you will then deploy to a production server. By the end of this book, you'll have the knowledge, skills, and confidence to advance your career and tackle your own ambitious projects with C#.

Dates

A date can be represented in C# using the DateTime value type. It is a struct with two static properties called MinValue, which is January 1, 0001 00:00:00, and MaxValue, which is December 31, 9999 11:59:59 P.M. As the names suggest, both these values represent the minimum and maximum dates according to the Gregorian calendar date format. The default value for DateTime objects is MinValue.

It is possible to construct a DateTime variable in various ways. Some of the most common ways are as follows:

  • Assigning the current time as follows:
    var now = DateTime.Now;

This sets the variable to the current date and time on the calling computer, expressed as the local time.

var now = DateTime.UtcNow;

This sets the variable to the current date and time on this computer, expressed as the Coordinated Universal Time (UTC).

  • You can also use constructors for passing days, months, years, hours, minutes, and even seconds and milliseconds.
  • There is also a special...
