Programming C# 6, Part 06 of 12: Strings, File I/O, and Data Types

Course description

The .NET framework is a collection of thousands of rich objects you can use in your code, and it’s one of the compelling reasons to use C#. Using .NET classes can save you a lot of work in providing basic infrastructure to your C# applications. In this course, you’ll learn about some of the many classes and objects the .NET framework, as well as more sophisticated techniques for using some of its more advanced data types. In particular, you’ll learn about the support the .NET framework provides for working with strings, files, and dates.

Each LearnNowOnline training course is made up of Modules (typically an hour in length). Within each module there are Topics (typically 15-30 minutes each) and Subtopics (typically 2-5 minutes each). There is a Post Exam for each Module that must be passed with a score of 70% or higher to successfully and fully complete the course.
