Question

有没有更好的方法在mvc 5 asp.net上集成rdlc报告。每个人都在使用iframe。但我不喜欢那个解决方案。

有没有优雅的解决方案？

如何在单独的标签中呈现rdlc报告？！

例如，

在您的控制器中：

 public ActionResult Report()
        {
            LocalReport localReport = new LocalReport();
            localReport.ReportPath = Server.MapPath("~/Reports/Report1.rdlc");

            // you may comment dbContext if the report is static or needs no DB-connection
            using (dbContext db = new dbContext())
            {
                ReportDataSource ds1 = new ReportDataSource("DataSet_Header", db.table_X.ToList());
                ReportDataSource ds2 = new ReportDataSource("DataSet_Detail", db.StoreedProcedure_X(5).ToList());
                // ...


                localReport.DataSources.Add(ds1);
                localReport.DataSources.Add(ds2);


                string mimeType;
                string encoding;
                string fileNameExtension;
                Warning[] warnings;
                string[] streams;
                string reportType = "PDF";
                string deviceInfo = "<DeviceInfo>" +
                    "<OutputFormat>PDF</OutputFormat>"+
                    "<PageWidth>11.69in</PageWidth>"+
                    "<PageHeight>8.27in</PageHeight>"+
                    "</DeviceInfo>";
                byte[] renderBytes;


               // add report parameters here, if any
               Microsoft.Reporting.WebForms.ReportParameter[] para = new ReportParameter[] {
                    new ReportParameter("sample", Sample.ToString())
                // , add more parameters if anymore exists ...
                };


                localReport.SetParameters(para);

                renderBytes = localReport.Render(
                    reportType,
                    deviceInfo,
                    out mimeType,
                    out encoding,
                    out fileNameExtension,
                    out streams,
                    out warnings
                    );

                return File(renderBytes, "application/pdf");
            } // end using
        }

在您看来：

您可以为上述操作方法创建<a>标签或@Html.ActionLink：

<a href="@Url.Action("Report", "controllerName")">PRINT</a>

希望这有帮助：）
