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.");
