Type Inference

In VB.NET, type inference allows you to declare a variable with a specific type. For example:

Dim x As Integer = 10

In Crystal, type inference is more flexible, allowing you to omit the type declaration:

x = 10

Reference: VB.NET Documentation on Variable Declaration

Properties with Getters and Setters

VB.NET allows you to define properties with getters and setters easily:

Public Property Name As String

In Crystal, properties are defined differently:

property name : String

Reference: VB.NET Properties

Event Handling

In VB.NET, event handling is done using AddHandler:

AddHandler Button.Click, AddressOf ClickMe

In Crystal, you can use a more concise syntax:

button.on_click(&.click_me)

Reference: VB.NET Events

Nullable Types

VB.NET supports nullable types using the ? syntax:

Dim x As Integer? = Nothing

In Crystal, you can represent a nullable type with nil:

x = nil

Reference: VB.NET Nullable Types

LINQ Queries

VB.NET uses LINQ for querying collections:

Dim result = From item In collection

In Crystal, you can achieve similar functionality with blocks:

result = collection.map { |item| ... }

Reference: LINQ in VB.NET

Exception Handling

VB.NET uses Try...Catch for exception handling:

Try
    ' Code
Catch ex As Exception
    ' Handle exception
End Try

In Crystal, the equivalent is:

begin
    # Code
rescue e : Exception
    # Handle exception
end

Reference: Exception Handling in VB.NET

String Interpolation

VB.NET supports string interpolation with $:

Dim message As String = $"Hello {name}"

In Crystal, you can use #{} for interpolation:

message = "Hello #{name}"

Reference: String Interpolation in VB.NET

Default Parameters

VB.NET allows default parameters in methods:

Sub MyMethod(Optional ByVal x As Integer = 0)

In Crystal, you can define default parameters like this:

def my_method(x = 0)

Reference: Default Parameters in VB.NET

Multidimensional Arrays

VB.NET supports multidimensional arrays:

Dim arr(,) As Integer

In Crystal, you can define them using nested arrays:

arr = Array(Array(Int32))

Reference: Multidimensional Arrays in VB.NET

Attributes and Annotations

VB.NET uses attributes like this:

<Obsolete("Use NewMethod")>

In Crystal, the syntax is slightly different:

@[Obsolete("Use NewMethod")]
