Property in vb.net...

as propert is a good way for both implementing encapsulationa nd data validation before the processing of data.

Property Procedure: - Here we can store the value and also can retrieve the value.

1.Enclosed within Property and End Property.
2.It uses two blocks known as Get and Set.
3.Set-> End Set, used for storing the value.
   Get-> End Get, used for returning or retrieving the   value.   
4.It returns the value.
5.It supports ByVal but not support ByRef.

Program
Public Class Form1

    Dim age As Integer
    Private Property Y() As Integer
        Get
            Return age
        End Get
        Set(ByVal Value As Integer)
            age = Value
            MsgBox("Age set")
        End Set
    End Property

    Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
        If TextBox1.Text = "" Then
            MsgBox("Please enter your age")
        Else
            Try
                Y = TextBox1.Text
            Catch ex As Exception
                MsgBox(ex.Message)
            End Try
            TextBox1.Clear()
        End If
    End Sub

    Private Sub Button2_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button2.Click
        MsgBox("Your age is: " & Y)
    End Sub
End Class
