Examples

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 void DemonstrateVersionNotFoundException()
{
    // Create a DataTable with one column.
    DataTable table = new DataTable("NewTable");
    DataColumn column = new DataColumn("NewColumn");
    table.Columns.Add(column);
    DataRow newRow;
  
    for(int i = 0;i <10;i++)
    {
        newRow = table.NewRow();
        newRow["NewColumn"] = i;
        table.Rows.Add(newRow);
    }
    table.AcceptChanges();

    try
    {
        Console.WriteLine("Trying...");
        DataRow removedRow = table.Rows[9];
        removedRow.Delete();
        removedRow.AcceptChanges();
        // Try to get the Current row version.
        Console.WriteLine(removedRow[0,DataRowVersion.Current]);

    }
    catch(System.Data.VersionNotFoundException)
    {
        Console.WriteLine("Current version of row not found.");
    }
}
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
