如何在C＃中将数据集绑定到Crystal报表

Question

我有一个数据库，我想在我的报告中使用它的几个表（Crystal Report）， 在我的代码中我有

        testdbDataSet ds = new testdbDataSet();

        testdbDataSetTableAdapters.ProductsTableAdapter productAdapter = new testdbDataSetTableAdapters.ProductsTableAdapter();
        productAdapter.Fill(ds.Products);

        testdbDataSetTableAdapters.RegionTableAdapter regionAdapter = new testdbDataSetTableAdapters.RegionTableAdapter();
        regionAdapter.Fill(ds.Region);  

        ds.AcceptChanges();

        ReportDocument reportDoc = new ReportDocument();
        reportDoc.FileName = "CrystalReport1.rpt";
        reportDoc.SetDataSource(ds);

        crystalReportViewer1.ReportSource = reportDoc;
        crystalReportViewer1.Show();

• ds是.XDS数据集的实例

crystalReportViewer不显示我的报告

我已经检查了stackoverflow上的this链接，但无法完成此操作

    testdbDataSet ds = new testdbDataSet();

    //FETCH FROM ANYWHERE TO a DataTable
    DataTable _DtFrmDBPrd = new DataTable();
    DataTable _DtFrmDBRgn = new DataTable();

    _DtFrmDBPrd = GetDataFrmDBPrd();//Filling the DataTable From DB or any where..
    _DtFrmDBRgn = GetDataFrmDBRgn();

    ds.Products.Merge(_DtFrmDBPrd);//Both the Data Table should have the same column name and Data Type
    ds.Region.Merge(_DtFrmDBRgn);

    ReportDocument reportDoc = new ReportDocument();
    reportDoc.FileName = "CrystalReport1.rpt";
    reportDoc.SetDataSource(ds);

    crystalReportViewer1.ReportSource = reportDoc;
    crystalReportViewer1.Show();
