The Modern C# Challenge

By: Rod Stephens

Overview of this book

C# is a multi-paradigm programming language. The Modern C# Challenge covers with aspects of the .NET Framework such as the Task Parallel Library (TPL) and CryptoAPI. It also encourages you to explore important programming trade-offs such as time versus space or simplicity. There may be many ways to solve a problem and there is often no single right way, but some solutions are definitely better than others. This book has combined these solutions to help you solve real-world problems with C#. In addition to describing programming trade-offs, The Modern C# Challenge will help you build a useful toolkit of techniques such as value caching, statistical analysis, and geometric algorithms. By the end of this book, you will have walked through challenges in C# and explored the .NET Framework in order to develop program logic for real-world applications.

Use the following problems to test your skills at working with dates, times, time zones, and date and time localization. Give each problem a try before you turn to the solutions and download the example programs.

41. Days of the week

Write a program that lets the user pick a birthdate from a MonthCalendar control. When the user clicks a button, display the days of the week for the next 10 birthdays after today's date.

42. Date and time picker

Normally, the DateTimePicker control lets the user display a date or a time, but not both. If you want to let the user select both a date and time in a single control, you need to set its Format and CustomFormat properties.

Write a program that lets the user select a date and time from a DateTimePicker control with a long date format and a short time format. These formats differ depending on the computer's locale. On my system, localized for the United States, the result would have the format Wednesday, April 1, 2020 4:13 PM.
