How Can I Achieve C#'s `dynamic` Functionality in VB.NET with Strict Type Enforcement?

Achieving C#'s dynamic Behavior in VB.NET with Strict Type Checking

C#'s dynamic keyword offers late binding and dynamic typing, simplifying interaction with objects of unknown or variable types. This is particularly useful when dealing with data structures that are inherently flexible or change during runtime.

VB.NET's closest equivalent is the Object type. However, VB.NET's strong typing system, governed by Option Strict, differs significantly from C#'s.

With Option Strict On (the VB.NET default), variables require explicit type declarations, and type conversions are strictly enforced. Therefore, a direct equivalent to C#'s dynamic isn't available.

Conversely, setting Option Strict Off allows Object to behave more like C#'s dynamic, enabling late binding. This means you can work with objects of unknown types without explicit type checking.

In essence, Object with Option Strict Off provides some similar functionality to C#'s dynamic, but it's crucial to understand that VB.NET's type system and Option Strict introduce constraints, preventing a complete parallel. The trade-off is flexibility versus the benefits of compile-time type safety.
