csharp

public void ProcessReader (ZohoBooksDataReader ZohoBooksReader)
{
  if (!ZohoBooksReader.IsClosed)
  {
    while (ZohoBooksReader.Read())
    {
      for (int i=0;i<ZohoBooksReader.FieldCount;i++)
      {
        Console.Write("\t"+ZohoBooksReader[i]);
      }
      Console.WriteLine();
    }
  }
  else
  {
    Console.WriteLine("The DataReader is closed. Rows affected in last action: "+ZohoBooksReader.RecordsAffected);
  }
}

Visual Basic

Public Sub ProcessReader(ByVal ZohoBooksReader As ZohoBooksDataReader)
  If Not ZohoBooksReader.IsClosed Then
    Dim i As Integer
    While ZohoBooksReader.Read()
      For i = 0 To ZohoBooksReader.FieldCount - 1
        Console.Write(" " & ZohoBooksReader(i))
      Next i
      Console.WriteLine()
    End While
  Else
    Console.WriteLine("The DataReader is closed. Rows affected in last action: " & ZohoBooksReader.RecordsAffected)
  End If
End Sub
