Hi Priya,

Create one vb.net web application and replace page load method with following

     Protected Sub Page_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load
        Dim MyArrList As ArrayList = New ArrayList()

        'Initialize Array
        MyArrList.Add(20)
        MyArrList.Add(18)
        MyArrList.Add(2)
        MyArrList.Add(10)
        MyArrList.Add(5)
        MyArrList.Add(90)

        'Sort elements in array to get smallest value
        MyArrList.Sort()

        'For displaying result
        Dim sbResult As StringBuilder = New StringBuilder()
        For I As Integer = 1 To 3 Step 1
            If I = 3 Then
                sbResult.Append(MyArrList(I - 1).ToString())
            Else
                sbResult.Append(MyArrList(I - 1).ToString() + ", ")
            End If
        Next

        'Displaying result on browser
        Response.Write("Smallest Three values are: " + sbResult.ToString())
    End Sub
