Every VB.NET program is made up of one or more statements. A VB.NET statement is a complete instruction that tells the program to perform a specific task, such as declaring a variable, displaying output, making a decision, or repeating a set of actions. In this VB.NET Statements Tutorial, you'll learn the different types of statements, understand VB.NET control statements, and see how they are used in real programs.
Types of VB.NET Statements
VB.NET statements are broadly classified into two categories:
Declaration Statements
Declaration statements are used to create programming elements such as variables, constants, methods, classes, and arrays. They define what the program can use during execution.
Dim studentName As String
Const TaxRate As Decimal = 0.18D
In this example, Dim declares a variable, while Const declares a constant.
Executable Statements
Executable statements perform actions when the program runs. They display output, assign values, call methods, and control the flow of execution.
Console.WriteLine("Welcome to VB.NET")
This statement prints a message to the console.
VB.NET Control Statements
VB.NET control statements determine the order in which code is executed. They help programs make decisions, repeat tasks, and change the flow of execution based on specific conditions.
The most common control statements include:
If...Then...Else – Executes code based on a condition.
Select Case – Chooses one block of code from multiple options.
For...Next – Repeats a block of code a fixed number of times.
While and Do...Loop – Repeat statements while a condition is true.
These statements are essential for building interactive and dynamic applications.
VB.NET Statements Tutorial Example
Dim marks As Integer = 80
If marks >= 50 Then
Console.WriteLine("Pass")
Else
Console.WriteLine("Fail")
End If
This example uses a declaration statement to create a variable and a control statement to decide which message to display.
Best Practices
Write one clear statement for each task.
Use meaningful variable and method names.
Indent control statements to improve readability.
Avoid unnecessary nested conditions to keep code simple.

Frequently Asked Questions
What exactly is a VB.NET statement?
Think of a VB.NET statement as a single, complete instruction for your program. Whether you're declaring a variable or running a loop, you're using a statement to tell your application exactly what to do next.
What's the main difference between declaration and executable statements?
It's all about timing and purpose. Declaration statements are your setup crew—they define variables, constants, and classes so your program knows what data it's working with. Executable statements are the workers; they perform the actual actions, like calculations or displaying output, when your program runs.
Why are VB.NET control statements so important?
Without control statements, your program would just run straight from top to bottom. Control statements (like If…Then and For…Next) are what make your application "smart." They allow your code to make decisions, repeat tasks, and adapt based on specific conditions.
Do you have any tips for writing cleaner code?
Absolutely! The best practice is to keep each statement focused on just one task. Use meaningful names for your variables so you don't have to guess what they do later, and keep your indentation consistent. It makes your code much easier to read—both for you and for anyone else who might work on it in the future.
