Default State for Structure Members

Problem
You want to know how to handle the default state of members in structures.

Solution
Create structures so that they’re in a valid state when their members are null or zero.

Comments
Defining parameterless constructors in structures is not permitted. It’s also illegal to define initial values for fields in structures. What happens is the CLR zeros out all fields when it creates the structure. As an example, consider a structure with a Boolean field or property. You’ll want to ensure that a false state is a valid initial value for it. Otherwise, you’ll want to rename the field to reverse its meaning.
