VB.NET Keywords

See the keywords in VB.NET. Keywords are used in declarations and statements.

Keywords. Programs combine parts. VB.NET has many keywords. We learn the meaning of these keywords. We then combine them into higher-level constructs and programs.

Some keywords (like For and While) map to looping constructs. And others (Class, Dim and Sub) are part of declarations. With keywords we compose programs.#Const #If #Region AddHandler AddressOf And AndAlso As Async Await Boolean ByRef Byte ByVal Case Catch Char Class Const Date Decimal Delegate Dim DirectCast Do Do Until Do While Double End Enum Event Exit False Finally For For Each Friend Function GetType GoTo Handles If Imports Inherits Integer Interface Is IsNot Iterator Long Me Mid Module MustInherit MyClass Namespace Not Nothing NotInheritable Object Of Optional Overloads Or OrElse ParamArray Partial Private Property Public RaiseEvent ReadOnly ReDim REM Return SByte Select Shadows Shared Short Single String Structure Sub SyncLock Throw True Try TryCast UInteger ULong UShort Using While With WithEvents WriteOnly Yield

Functions. The VB.NET language provides built-in functions that convert types. These are often implemented with other .NET Framework constructs.Asc Chr Mod Val

Types. Here is a list of common types in the .NET Framework. We use these types with VB.NET code. Not all types are included in this list.Array ArrayList Console DataRow DataSet DataTable DateTime Exception File HashSet Hashtable HttpClient IEnumerable KeyValuePair List Process Queue Random Regex Stack StreamReader StreamWriter String StringBuilder Task Timer TimeSpan Tuple

Math. Many mathematical functions are available in the System namespace. The Math class provides these. With Math, we avoid implementing this logic.Math.Abs Math.Ceiling Math.Floor Math.Max Math.Min Math.Round Math.Sqrt Math.Truncate

Algorithms. Here we combine data structures and functions to achieve complex tasks. An algorithm is a well-known (or complex) method.Algorithm: Fibonacci Algorithm: Levenshtein

Windows. The Windows Forms platform supports Windows GUI programs. And the VB.NET language can be used to control these programs. We run code as a result of event handlers.BackgroundWorker Button DataGridView MessageBox.Show OpenFileDialog TextBox

Syntax. The VB.NET language is easy to read. It has clear rules. It has predictable logic. But some complexity exists in the language.<X> (Attribute):= (Named argument)X? (Nullable)"${x}" (String interpolation)

Contextual. Some keywords are used together (For and Each). They change meaning when used part of a larger construct. And some words (like from LINQ) are contextual and not listed above.

Many keywords, like SyncLock, are narrow in their utility. VB.NET retains older language terms like "Mid" and "Date." These have been replaced with newer .NET Framework methods.

With this language, we access the full power of the .NET Framework. Many programs are written in VB.NET. A developer who understands VB.NET is in a good position.
