A developer is working with a Purchase Order automation process.

To convert string values to integers and multiply them, we should use:

Convert.ToInt32(ShippedContainers) * Convert.ToInt32(ItemsPerContainer)

Why is Option D Correct?

Convert.ToInt32() is a standard .NET method that safely converts strings to integers.

This method handles null values better than .ToInt32().

It ensures that arithmetic operations can be performed correctly.

Why Other Options Are Incorrect?

A (ShippedContainers.ToInt32()) ❌

ToInt32() is not a valid method for String objects in VB.NET.

B (String.ToInt32()) ❌

String.ToInt32() does not exist in VB.NET.

C (CInt(ShippedContainers * ItemsPerContainer)) ❌

The multiplication must be done after conversion, not before.
