How to work in Winforms Crystal Report with Object Data Source?

So far I have found web-links to use Crystal Report with DataSets or Databases directly.

Can anyone show me how to do it like this?

        <CR:CrystalReportViewer ID="crvmyDataReport" runat="server" 
            ReportSourceID="crsmyData" EnableDatabaseLogonPrompt="False" DisplayGroupTree="False" 
            EnableParameterPrompt="False" ReuseParameterValuesOnRefresh="True" 
            BorderStyle="Solid" BorderColor="Black" BorderWidth="1px" />
        <br />
        <CR:CrystalReportSource ID="crsmyData" runat="server">
            <Report FileName="myData.rpt">

                </DataSources>
            </Report>
        </CR:CrystalReportSource>
