The user-defined type (UDT)
supported by previous versions of Visual Basic is generalized to a structure in
Visual Basic .NET. A structure is a concatenation of one or more members of
various data types. The structure is treated as a single unit, although its
members can also be accessed individually.
A structure declaration starts with
the Structure statement and ends with the End Structure statement. The Structure
statement supplies the name of the structure, which is also the identifier of
the data type being defined by the structure. Other parts of the code can use
this identifier to declare the data type of variables, arguments, and function
return values.
The following paradigm shows the
declaration of a structure.
[Public | Protected | Friend |
Protected Friend | Private] Structure structname
{Dim | Public |
Friend | Private} member1 As datatype1
...
{Dim
| Public | Friend | Private} memberN As datatypeN
End Structure
The
declarations between the Structure and End Structure statements define the
members of the structure. Every member must be declared using a Dim statement or
a statement that specifies access, such as Public, Private, or Friend. If a Dim
statement is used, the access defaults to public.
A reference type that
encapsulates data (constants and fields) and behavior (methods, properties,
indexers, events, operators, instance constructors, static constructors, and
destructors), and can contain nested types. Class types support inheritance, a
mechanism whereby a derived class can extend and specialize a base class. See
also: encapsulation, indexer, property, reference type.

What is the difference between the structure and class and
where exactly the Structre is used.
I saw a code which is normally will be in a class but the
following Methods and Property were there in a Structure
Public Interface IAccount
Sub MakeDeposit(ByVal Amount As
Decimal)
ReadOnly Property Balance() As
Decimal
End Interface
Public Structure AccountInfo
Implements IAccount
Public m_Balance As Decimal
Public Sub MakeDeposit(ByVal Amount As
Decimal) Implements
IAccount.MakeDeposit
m_Balance += Amount
End Sub
Public ReadOnly Property Balance() As
Decimal Implements
IAccount.Balance
Get
Return m_Balance
End Get
End Property
End Structure
I know that Implementation of the Interface IAccount is
done in the Structure, but the question is where exactly this
structure is used? and why they have not Implemented in a
Class?
