先上重点

        #region 设置多个报表数据源         //此部分代码比较消耗时间！！！

        public ReportDocument FillReportData(DataSet Ds, ReportDocument oReport)

        {

            this.SetData(Ds, oReport);

            foreach (ReportDocument oSubReport in oReport.Subreports)

                this.SetData(Ds, oSubReport);

            return oReport;

        }



        private void SetData(DataSet Ds, ReportDocument oReport)

        {

            foreach (Table oTable in oReport.Database.Tables)

                oTable.SetDataSource(Ds.Tables[oTable.Name.ToString()]);

        }

        #endregion
