Convert VB.NET to TypeScript using AI

Features

• Translation of invalid or incomplete source code
• Customizable conversion via inline instructions, use tag in comments
• Convert unformatted source code snippets
• Translation of complex syntax expressions
• Syntax, semantic and pragmatic of target programming language is considered during translation

Event Handling

In VB.NET, event handling is done using AddHandler to associate an event with a method. In TypeScript, event handling is typically done using addEventListener.

VB.NET Example:

AddHandler Button1.Click, AddressOf Button1_Click

Private Sub Button1_Click(sender As Object, e As EventArgs)
    ' Handle the click event
End Sub

TypeScript Example:

button1.addEventListener('click', button1Click);

function button1Click(event: MouseEvent) {
    // Handle the click event
}

Properties with Getters and Setters

VB.NET allows properties to be defined with Get and Set accessors. TypeScript uses getter and setter methods.

VB.NET Example:

Public Property Name As String
    Get
        Return _name
    End Get
    Set(value As String)
        _name = value
    End Set
End Property

TypeScript Example:

private _name: string;

get name(): string {
    return this._name;
}

set name(value: string) {
    this._name = value;
}

Optional Parameters

VB.NET supports optional parameters with default values, while TypeScript uses the ? syntax.

VB.NET Example:

Sub MyMethod(Optional ByVal x As Integer = 0)
    ' Method implementation
End Sub

TypeScript Example:

function myMethod(x?: number) {
    // Method implementation
}

VB.NET Documentation on Optional Parameters

Overloaded Methods

VB.NET allows method overloading based on parameter types. TypeScript also supports method overloading but requires a different syntax.

VB.NET Example:

Overloads Function Add(x As Integer, y As Integer) As Integer
    Return x + y
End Function

Overloads Function Add(x As String, y As String) As String
    Return x & y
End Function

TypeScript Example:

function add(x: number, y: number): number;
function add(x: string, y: string): string;
function add(x: any, y: any): any {
    return x + y;
}

Delegates and Lambdas

VB.NET uses delegates to encapsulate methods, while TypeScript uses function expressions or arrow functions.

VB.NET Example:

Dim myDelegate As New Action(AddressOf MyMethod)

Private Sub MyMethod()
    ' Method implementation
End Sub

TypeScript Example:

const myDelegate = () => myMethod();

function myMethod() {
    // Method implementation
}

Exception Handling

Both languages support exception handling, but the syntax differs slightly.

VB.NET Example:

Try
    ' Code that may throw an exception
Catch ex As Exception
    ' Handle exception
End Try

TypeScript Example:

try {
    // Code that may throw an exception
} catch (ex) {
    // Handle exception
}

VB.NET Documentation on Exception Handling

Default Values for Parameters

VB.NET allows default values for parameters, similar to TypeScript.

VB.NET Example:

Function MyFunction(Optional ByVal x As Integer = 10) As Integer
    Return x
End Function

TypeScript Example:

function myFunction(x: number = 10): number {
    return x;
}

VB.NET Documentation on Default Parameter Values

Multidimensional Arrays

VB.NET supports multidimensional arrays, while TypeScript uses arrays of arrays.

VB.NET Example:

Dim arr(2, 2) As Integer

TypeScript Example:

let arr: number[][] = [[0, 0, 0], [0, 0, 0]];

VB.NET Documentation on Arrays

With Statement

VB.NET has a With statement for simplifying code that accesses multiple properties of an object. TypeScript does not have a direct equivalent.

VB.NET Example:

With myObject
    .Property1 = value1
    .Property2 = value2
End With

TypeScript Example:

Object.assign({}, myObject); // No direct equivalent

VB.NET Documentation on With Statement

Type Inference

VB.NET allows type inference with the Dim keyword, while TypeScript has a more flexible type inference system.

VB.NET Example:

Dim x = 10

TypeScript Example:

let x = 10; // TypeScript infers the type as number
