Topics such as whether a string is a valid number, rounding a floating point value, as well as other forms of numeric testing.

As with all of the Cookbook series, C# 3.0 Cookbook 3rd Edition presents the problem, gives you the solution and then presents a discussion about the solution. Sometimes the discussion is brief, and sometimes it can last pages depending on the complexity of the problem. At the end of each recipe is a "see also" section that directs you to further information on the topic. This gives you the opportunity to understand the problem, solve it and learn about any potential trade-offs to the solution.

Along with the presentation of the solutions, what I like about C# 3.0 Cookbook, 3rd Edition is that it is the go-to book for solving problems. While it is not the kind of book that you can learn C# with, it is the kind of book that you want to have around when you are learning C#. It will also help you grow as a developer and save you time, energy, and frustration when you need it most. If you are a C# developer, or is someone who is learning C# and wants to grow in their abilities then I highly recommend C# 3.0 Cookbook 3rd Edition.
