You can use ReportViewer for this like:

C#

private void CreatePDFFromRdlc(string fileName)
{
    Warning[] warnings;
    string[] streamIds;
    string mimeType = string.Empty;
    string encoding = string.Empty;
    string extension = string.Empty;

    // Setup the report viewer object and get the array of bytes
    ReportViewer viewer = new ReportViewer();
    viewer.ProcessingMode = ProcessingMode.Local;
    viewer.LocalReport.ReportPath = "AdmitcardPst.rdlc";

    byte[] bytes = viewer.LocalReport.Render("PDF", null, out mimeType, out encoding, out extension, out streamIds, out warnings);

    // Now that you have all the bytes representing the PDF report, buffer it and send it to the client.
    Response.Buffer = true;
    Response.Clear();
    Response.ContentType = mimeType;
    Response.AddHeader("content-disposition", "attachment; filename=" + fileName + "." + extension);
    Response.BinaryWrite(bytes); // create the file
    Response.Flush();
}

Hope this helps!
