Question

I stumbled upon this issue:

myObject‘s class has a public field MyField which type is Decimal?

I accidentally access the field as if it were a property with this code:

myObject.MyField()

instead of

myObject.MyField

And I got the following error from the compiler: Structure 'Decimal?' cannot be indexed because it has no default property

Documentation on this error on MSND is very short and I just don’t understand what it means.

Q: What’s the meaning of myObject.MyField() if it has one, and why can’t I use it on my field if so?

Note: my problem is now solved but I would like to understand…

Answer 1

You access elements of an array using () in VB.NET. The error message is telling you Structure 'Decimal?' cannot be indexed because it can’t.
