Code for creating structure:

The following code creates a structure named 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 = 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)



    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.
