我正在尝试从ASP.NET C#导出Crystal报表到PDF格式。我希望将它直接下载到客户端。

当我点击按钮时,没有任何反应。

            string parameter = ViewState["strInvoiceID"].ToString();
            TableLogOnInfo logOnInfo = new TableLogOnInfo();

            logOnInfo.ConnectionInfo.ServerName = System.Configuration.ConfigurationManager.AppSettings["Server"];
            logOnInfo.ConnectionInfo.DatabaseName = System.Configuration.ConfigurationManager.AppSettings["Database"];
            logOnInfo.ConnectionInfo.IntegratedSecurity = false;
            logOnInfo.ConnectionInfo.UserID = System.Configuration.ConfigurationManager.AppSettings["UID"];
            logOnInfo.ConnectionInfo.Password = System.Configuration.ConfigurationManager.AppSettings["PWD"];

            ReportDocument rd = new ReportDocument();
            string reportPath = Server.MapPath("InvoiceReport.rpt");
            rd.Load(reportPath);

            foreach (CrystalDecisions.CrystalReports.Engine.Table tbl in rd.Database.Tables)
                tbl.ApplyLogOnInfo(logOnInfo);


            ParameterValues crParameterValues = new ParameterValues();
            ParameterDiscreteValue crParameterDiscreteValue = new ParameterDiscreteValue();
            crParameterDiscreteValue.Value = parameter;

            rd.DataDefinition.ParameterFields["InvoiceID"].CurrentValues.Clear();
            crParameterValues.Add(crParameterDiscreteValue);
            rd.DataDefinition.ParameterFields["InvoiceID"].ApplyCurrentValues(crParameterValues);

            Response.Buffer = false;
            Response.ClearContent();
            Response.ClearHeaders();
            rd.ExportToHttpResponse(ExportFormatType.PortableDocFormat, Response, true, "Invoice" + parameter + ".pdf");

感谢您的帮助。 此外,还有更优化的方法将参数传递给报告吗?

答案 0 :(得分:0)

根据您要将其导出到的位置,尝试将其保存到磁盘:

rd.ExportToDisk(ExportFormatType.PortableDocFormat, "C:\report.pdf");

希望有所帮助,

编辑:

尝试将asAttachment参数设置为false,看看会发生什么:

  rd.ExportToHttpResponse(ExportFormatType.PortableDocFormat, Response, false, 
 "Invoice" + parameter + ".pdf");
