Can VB.NET Achieve Dynamic Typing While Maintaining Type Safety?

How to implement the equivalent function of C# 'dynamic' keyword in VB.NET and maintain type safety?

In C#, the 'dynamic' keyword allows dynamic typing, where the type of a variable is not determined until runtime. However, in VB.NET, type safety is enforced by default via the 'Option Strict' setting.

When 'Option Strict' is set to 'On', all variables must explicitly declare their type. So, in VB.NET, is it possible to implement dynamic typing while maintaining type safety?

The answer is: It cannot be implemented directly. The 'Object' type in VB.NET is equivalent to 'dynamic' in C#, but it requires 'Option Strict' to be set to 'Off'. When 'Option Strict Off', type safety is disabled, allowing late binding and implicit conversions.

However, if you need to maintain type safety, there is no direct equivalent of the C# 'dynamic' keyword in VB.NET. You can instead use type casting or reflection to dynamically access members and properties.
