VersionNotFoundException Class
Represents the exception that is thrown when you try to return a version of a DataRow that has been deleted.
Assembly: System.Data (in System.Data.dll)
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") table.Columns.Add(column) Dim newRow As DataRow Dim i As Integer For i = 0 To 9 newRow = table.NewRow() newRow("NewColumn") = i table.Rows.Add(newRow) Next i table.AcceptChanges() Try Console.WriteLine("Trying...") Dim removedRow As DataRow = table.Rows(9) removedRow.Delete() removedRow.AcceptChanges() ' 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
