Reportview 如何动态绑定多张表？

reportViewer1.LocalReport.DataSources.Clear();
this.reportViewer1.LocalReport.DataSources.Add(new Microsoft.Reporting.WinForms.ReportDataSource("Notice",data.Notice));
this.reportViewer1.LocalReport.DataSources.Add(new Microsoft.Reporting.WinForms.ReportDataSource("Details", data.Details));
this.reportViewer1.RefreshReport();
上面我的绑定代码，两张表同过一个ID想关联，总提示找不到关系数据源
