This Article shows how to use structure in VB.NET.
Structures:-
A user defined data type .They are user-defined and provide a method for packing together data of different types.
Use structure keyword to declare the structure
It is value type and store on Stack
Cannot have explicit default constructor but can have parameterized constructors
Cannot have destructor
Cannot participate in inheritance
Structure members can be private as well
Code for creating
structure:
The following code creates a
structure named Customer.
Structure Customer
Private custid As Integer
Private name As String
Private balance As Double
Public Sub New(ByVal custid
As Integer,
ByVal name As String, ByVal
opamt As Double)
Me.custid = custid
Me.name = name
balance = opamt
End Sub
Public Sub
Deposit(ByVal amount As Double)
balance += amount
End Sub
Public Sub
ShowAccount()
Console.WriteLine("Balance
of {0} is {1}", name, balance)
End Sub
End Structure
Class StructTest
Public Shared Sub Main()
Dim c As New Customer(1234,
"Rakesh Verma", 9000)
c.Deposit(5000)
c.ShowAccount()
End Sub
End Class
OUTPUT of
the above code:
Difference between Class and Structure:These are the main difference between classes and structures.
classes are Reference types and structures are Value types.
structures are used for smaller lightweight objects that do notpersist for long and classes are used for larger objects that are expected to existin memory for long periods.
We declare a structure in Visual Basic .NET with the Structure keyword.
