Please see the article "Crystal Report in Silverlight 5" in my blog.
and show the rdl report by the following

                LocalReport localReport = new LocalReport();
                localReport.ReportPath = Server.MapPath("~/ClientBin/Reports/" + reportFileName + ".rdlc");

DataSetName = "DatasetofReport";

                PageHeight = 9;
                localReport.SetParameters(new ReportParameter("CompanyName", "Shohel LTD", true));                
                var DataList= which is getting from xml file or binary file
                RenderRDLCReport(DataList, reportFileName, localReport);
