I Corrected the Above Code and now its Working
public ActionResult GetPdfReport()
{
NetworkCredential nwc = new NetworkCredential("username", "password");
WebClient client = new WebClient();
client.Credentials = nwc;
string reportURL = "http://someIp/ReportServer/?%2fReportProjectName/ReportName&rs:Command=Render&rs:Format=PDF";
return File(client.DownloadData(reportURL), "application/pdf");
}
i do not found any other alternative than this to export SSRS Report in MVC without using ReportViewer.
