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 random numbers and randomization. Give each problem a try before you turn to the solutions and download the example programs.

49. Random doubles

The Random class provides three overloaded versions of its Next method; one that returns a random integer, one that returns an integer between zero and an upper limit, and one that returns an integer between lower and upper limits.

Strangely, the Random class provides only one version of its NextDouble method. That version returns a double value between 0.0 and 1.0.

Add a NextDouble extension method to the Random class to return a random double value between lower and upper bounds.

50. Random items

Add a RandomItem extension method to a generic array to return a randomly selected item from the array. Write a second extension method to do the same for a generic list of items.

51. Randomize items

Write Randomize extension methods to randomize the items in a generic array or list.

52. Random...
