I am unable to use crystal report?

I am unable to use crystal report? i have a file crystalreport1.rpt and a crystalreportviewer.

I am unable to create the object of crystalreport1.rpt.

crystalreport1 cr=new crystalreport1(); //not able to create object of crystalreport1.rpt

 //CrystalReportViewr1.ReportSource = ds;
 //CrystalReportViewr1.DataBind(); 

how do i solve this > 开发者_开发知识库

try using the relevant namespaces....

using CrystalDecisions.CrystalReports.Engine;

then you can easily create objects for crystal reports.
