Structures can be used as a base for other structures.

A structure can implement one or more interfaces.

Structure members can be methods, fields, indexers, properties, operator methods, and events.

Structures can also define constructors, but not destructors. And you cannot define a default (parameterless) constructor for a structure.

Value type variables are stored on stack. Reference type variables are stored on heap.

Value type holds the data directly, Reference type points to the location that holds the data.

Value type cannot contain null value. Reference type can contain null value.

A new type cannot be derived from value type. A new type can be derived from reference type.
