This highly interactive module begins with a simple “Hello, World!” program and proceeds to cover common concepts such as conditional statements, loop statements, and methods in C#. It also reflects upon the idea of arrays as well as the power they give to the programmer to write better code. Finally, it teaches us about exception handling in C# through interactive challenges and exercises.

C# for Programmers: A Practical Guide

## Introduction
Catching the problem is a good idea, but it can sometimes leave your program in an invalid state. 

For example, if you open a connection to a database, an error occurs and you throw an exception. Where would you close the connection? In both the try AND catch blocks? Well, problems may occur before the close is carried out.

Therefore, the **finally statement allows you to cater for the "in all cases do this" circumstance.**

### Example
See the example below:
