Question

What happens when i set a variable to nothing in VB.NET?
Is it true that nothing equals to default, or am i missing something here?

Answer 1

If it’s a value type (like Integer, Double, etc.) setting the variable to Nothing will set it to the default value.

If it’s a reference type, it will really be set to Nothing (null value).

In Microsoft’s words:

Assigning Nothing to a variable sets
it to the default value for its
declared type.

If the variable is of a reference
type, a value of Nothing means that
the variable is not associated with
any object. The variable has a null
value.
