View RDLC Report as pdf in Asp.net MVC

Question

I am facing problem in last two days. I am trying to view rdlc report as pdf without reportviewer. I export rdlc to pdf using the following code...

public string Export(LocalReport rpt, string filePath)
    {
        string ack = "";
        try
        {                
            Warning[] warnings;
            string[] streamids;
            string mimeType;
            string encoding;
            string extension;

            byte[] bytes = rpt.Render("PDF", null, out mimeType, out encoding, out extension, out streamids, out warnings);
            using (FileStream stream = File.OpenWrite(filePath))
            {
                stream.Write(bytes, 0, bytes.Length);
            }
            return ack;
        }
        catch(Exception ex)
        {
            ack = ex.InnerException.Message;
            return ack;
        }           
    }

The pdf file exported to User->AppData->Temp

            string filePath = System.IO.Path.GetTempFileName();
            string ack = Export(rpt, Server.MapPath("~/Reports/Mymun_Lab/ComparisonStudy.rdlc"));                
            System.Diagnostics.Process.Start(filePath);

I want to render this pdf file to the client PC.

This Code is work fine on my local machine. But when i publish this to IIS Server and run for try to get the exported pdf file to client PC not success. How can i solve this issue. Can anyone help me.

Thanks In Advance...

Finally, i found one solution about view RDLC report as pdf in asp.net MVC. The solution is following....

public FileResult ViewReport()
    {            
        string RptPath = Server.MapPath("~/Reports/Mymun_Lab/ComparisonStudy.rdlc");                  
        Microsoft.Reporting.WebForms.LocalReport rpt = new Microsoft.Reporting.WebForms.LocalReport(); 

        /* Bind Here Report Data Set */

        rpt.ReportPath = RptPath;
        string filePath = System.IO.Path.GetTempFileName();               
        Export(rpt, filePath);
        //CLOSE REPORT OBJECT           
        rpt.Dispose();
        return File(filePath, "application/pdf");
    } 

I use the following method for generate pdf from RDLC....

public string Export(LocalReport rpt, string filePath)
{
    string ack = "";
    try
    {                
        Warning[] warnings;
        string[] streamids;
        string mimeType;
        string encoding;
        string extension;

        byte[] bytes = rpt.Render("PDF", null, out mimeType, out encoding, out extension, out streamids, out warnings);
        using (FileStream stream = File.OpenWrite(filePath))
        {
            stream.Write(bytes, 0, bytes.Length);
        }
        return ack;
    }
    catch(Exception ex)
    {
        ack = ex.InnerException.Message;
        return ack;
    }           
}
