Public Class VersionNotFoundException _
	Inherits DataException
Dim instance As VersionNotFoundException

The following example creates a DataTable with one DataColumn and ten DataRow objects. After deleting a DataRow, trying to return the removed row's current version causes a VersionNotFoundException exception being thrown.

Private Sub DemonstrateVersionNotFoundException()
    ' Create a DataTable with one column. 
    Dim table As New DataTable("NewTable")
    Dim column As New DataColumn("NewColumn")
    Dim newRow As DataRow

    Dim i As Integer 
    For i = 0 To 9
        newRow = table.NewRow()
        newRow("NewColumn") = i
    Next i

        Dim removedRow As DataRow = table.Rows(9)

        ' Try to get the Current row version.
        Console.WriteLine(removedRow(0, DataRowVersion.Current))

    Catch e As System.Data.VersionNotFoundException
        Console.WriteLine("Current version of row not found.")
    End Try 
End Sub
