    Example
    This sample shows how to find out how many rows have been affected during last query. You can do it even if the SqlShimDataReader has been closed.
    public void ProcessReader (ExactTargetDataReader exactTargetReader)
    {
      if (!exactTargetReader.IsClosed)
      {
        while (exactTargetReader.Read())
        {
          for (int i=0;i<exactTargetReader.FieldCount;i++)
          {
            Console.Write("\t"+exactTargetReader[i]);
          }
          Console.WriteLine();
        }
      }
      else
      {
        Console.WriteLine("The DataReader is closed. Rows affected in last action: "+exactTargetReader.RecordsAffected);
      }
    }
    Public Sub ProcessReader(ByVal exactTargetReader As ExactTargetDataReader)
      If Not exactTargetReader.IsClosed Then
        Dim i As Integer
        While exactTargetReader.Read()
          For i = 0 To exactTargetReader.FieldCount - 1
            Console.Write(" " & exactTargetReader(i))
          Next i
          Console.WriteLine()
        End While
      Else
        Console.WriteLine("The DataReader is closed. Rows affected in last action: " & exactTargetReader.RecordsAffected)
      End If
    End Sub
