ASP.Net MVC 访问 SSRS 报告并导出到 pdf 不使用 ReportViewer

Question

So, I am using SSRS to generate reports and I have a server where my reports are stored. Now I need to download them and I have this code in my controller:

public ActionResult Export(string id)
{
     NetworkCredential nwc = new NetworkCredential("username", "password");
     WebClient client = new WebClient();
     client.Credentials = nwc;
     client.UseDefaultCredentials = true;

     client.Credentials = CredentialCache.DefaultCredentials;

     string reportURL = "http://desktop-4gpisbo:8080/teste/report/RelatorioPrincipal/&rs:Command=Render&rs:Format=PDF&rc:Toolbar=false&rc:Parameters=false&id=" + id;
     return File(client.DownloadData(reportURL), "application/pdf");
}

But it is giving me a PDF that is impossible to open or when it opens it says that is unavailable. The id is being passed via JQuery in my view, where it gets the Id from the URL then sends it to the controller, because my report is dynamic, I need different information depending on the user.

What is wrong with this code?

PS: The report is running on my localhost not on a server

    private void SetDataSources(object sender, SubreportProcessingEventArgs e)
    {
        e.DataSources.Add(new 
         ReportDataSource("DataSources1",TempData["DataSources1"]));
               
     }

 public FileResult ExportToPDF(TableViewModel data, string setToken)
  {
     var ProjectsList = from project in ProjectList
                        select new
                        {
                            project.ID,
                            project.Name,
                                  
                        };

            ReportViewer ProjectListReportViewer = new ReportViewer();
            ProjectListReportViewer.LocalReport.ReportPath = 
            Server.MapPath("~/Views/Reports/Reprot.rdlc");
            ProjectListReportViewer.LocalReport.DataSources.Clear();
            ReportDataSource rdc = new ReportDataSource("DataSet1", ProjectsList);

        
            ProjectListReportViewer.LocalReport.SubreportProcessing += new 
            SubreportProcessingEventHandler(SetProjectsDetail);
            ProjectListReportViewer.LocalReport.DataSources.Add(rdc);
            ProjectListReportViewer.LocalReport.EnableExternalImages = true;
            ProjectListReportViewer.LocalReport.Refresh();

            Warning[] warnings;
            string[] streamIds;
            string mimeType = string.Empty;
            string encoding = string.Empty;
            string extension = string.Empty;

            byte[] bytes = ProjectListReportViewer.LocalReport.Render("PDF", null, 
              out mimeType, out encoding, out extension, out streamIds, ouwarnings);
            
            ControllerContext.HttpContext.Response.Cookies.Add(new 
            HttpCookie("getToken", setToken));
 return File(bytes, System.Net.Mime.MediaTypeNames.Application.Octet, "Report.pdf");
        }
