[水晶报表]服务器后台自动生成PDF等档案

 记得以前用JDE ERP的时候，通过过设置参数自动跑报表。

我现在两个设想：第一，邮件预警也可以采取附件形式，有些情况配合附件 第二，单据审批完后自动保存当时的一份PDF文档。

方法：搭载水晶报表实现

private void Print(string pricingcode)
    {
        SqlParameter[] parms = new SqlParameter[1];
        parms[0] = new SqlParameter("@PricingCode", SqlDbType.NVarChar, 20);
        parms[0].Value = pricingcode;

        DataSet ds = new DataSet();
        DABaseAccess db = new DABaseAccess();
        ds = db.GetTableByStore("UP_GetQuo", parms).DataSet;

        if (ds != null)
        {

            CrystalDecisions.CrystalReports.Engine.ReportDocument doc = new CrystalDecisions.CrystalReports.Engine.ReportDocument();
            string reportPath = Server.MapPath("..\\..\\ERP\\Reports\\Quotation.rpt");
            doc.Load(reportPath);
            doc.SetDataSource(ds.Tables[0]);

            CrystalReportViewer1.ReportSource = doc;
            CrystalReportViewer1.DataBind();

            string filetype = "";
            filetype = "PDF";
            string contenttype = "";
            //string myfilename = Request.MapPath(".\\") + Session.SessionID + "." + filetype;//目录地址 注意反义字符
            string myfilename = "E:\\OA\\uploads\\quotation\\"+System .DateTime.Now .Year +"\\"+ pricingcode + "报价单" + Baseclass.getLongData().ToString() + "." + filetype;
            CrystalDecisions.Shared.DiskFileDestinationOptions mydiskoptions = new CrystalDecisions.Shared.DiskFileDestinationOptions();
            mydiskoptions.DiskFileName = myfilename;
            CrystalDecisions.Shared.ExportOptions myExportOptions = new ExportOptions();//oCR.ExportOptions; 
            myExportOptions.DestinationOptions = mydiskoptions;
            myExportOptions.ExportDestinationType = CrystalDecisions.Shared.ExportDestinationType.DiskFile;

            contenttype = "application/pdf";
            myExportOptions.ExportFormatType = CrystalDecisions.Shared.ExportFormatType.PortableDocFormat;

            doc.Export(myExportOptions); //输出报表 到服务器端的制定路径 
            //Response.ClearContent();     //清空页面 
            //Response.ClearHeaders();
            //Response.ContentType = contenttype;
            //Response.WriteFile(myfilename);//直接写入页面,页面平铺 可实现在线阅读功能
            //Response.Flush();
            //Response.Close();
        }
        else
        {
            JScript.Alert("没有找到记录", this.Page);
        }
    }
