Visual Basic 2015 Unleashed

Loops

As in the previous versions of the language, Visual Basic 2015 offers two kinds of loops: Do..Loop and While..End While. This section describes them both.

Do..Loop

The Do..Loop is the most frequently used loop in Visual Basic, and it’s also the most flexible. This loop can have two behaviors: repeating a set of actions until a condition is false and repeating a set of actions until a condition is true. The first scenario is accomplished by using a Do While statement, as demonstrated in Listing 4.3.
