Variables
Variables are storage locations and in VB.NET must have a specific type. When declared within method, property, or indexer declarations, variables are said to be local. Variables are declared in the following way:
Dim variablename As Type
So, to create an integer variable, we could write this:
Dim x As Integer
Variables must be assigned a value before they can be used, and we can both declare and assign a value to a variable in one step:
Dim x as Integer = 1
