生成 .rdlc 报告在本地有效，但在部署到 Azure 后无效

Question

在我的 ASP.NET MVC 5 应用程序中，我有以下方法：

public ActionResult SendMailAsAStudent(string studentId, string companyId, int applicationId, string companyCVR, string studentCPR)
        {
            var manager = new UserManager<ApplicationUser>(new UserStore<ApplicationUser>(new ApplicationDbContext()));
            var student = manager.FindById(studentId);
            var company = manager.FindById(companyId);
            var application = db.Applications.Find(applicationId);
            Project projectobj = db.Projects.Find(application.ProjectId);


            var myMessage = new SendGridMessage();
            myMessage.From = new MailAddress("info@leepio.dk");
            myMessage.AddTo(student.Email);
            myMessage.AddTo(company.Email);
            myMessage.Subject ="The contract for " + projectobj.Title + " is signed!";
            myMessage.Html = "Here is the final contract";

            LocalReport localReport = new LocalReport();
            localReport.ReportPath = Server.MapPath("~/Contracts/Contract.rdlc");

            ReportParameter cvrParameter = new ReportParameter("cvrParameter", companyCVR);
            ReportParameter companyNameParameter = new ReportParameter("companyNameParameter", company.CompanyName);
            ReportParameter companyAddressParameter = new ReportParameter("companyAddressParameter", company.Address);
            ReportParameter studentNameParameter = new ReportParameter("studentNameParameter", student.FirstName+" "+student.LastName);
            ReportParameter studentAddressParameter = new ReportParameter("studentAddressParameter", student.Address);
            ReportParameter studentZipCodeParameter = new ReportParameter("studentZipCodeParameter", student.ZipCode);
            ReportParameter jobStartDateParameter = new ReportParameter("jobStartDateParameter", projectobj.StartDate);
            ReportParameter jobEndDateParameter = new ReportParameter("jobEndDateParameter", projectobj.EndDate);
            ReportParameter jobDescriptionParameter = new ReportParameter("jobDescriptionParameter", projectobj.Description);
            ReportParameter jobHoursPerWeekParameter = new ReportParameter("jobHoursPerWeekParameter", projectobj.HoursPerWeek.ToString());
            ReportParameter jobHourlyRateParameter = new ReportParameter("jobHourlyRateParameter", projectobj.HourlyRate.ToString());
            ReportParameter cprParameter = new ReportParameter("cprParameter", studentCPR);

            localReport.SetParameters(new ReportParameter[] { cprParameter });
            localReport.SetParameters(new ReportParameter[] { cvrParameter });
            localReport.SetParameters(new ReportParameter[] { companyNameParameter });
            localReport.SetParameters(new ReportParameter[] { companyAddressParameter });
            localReport.SetParameters(new ReportParameter[] { studentNameParameter });
            localReport.SetParameters(new ReportParameter[] { studentAddressParameter });
            localReport.SetParameters(new ReportParameter[] { studentZipCodeParameter });
            localReport.SetParameters(new ReportParameter[] { jobStartDateParameter });
            localReport.SetParameters(new ReportParameter[] { jobEndDateParameter });
            localReport.SetParameters(new ReportParameter[] { jobDescriptionParameter });
            localReport.SetParameters(new ReportParameter[] { jobHoursPerWeekParameter });
            localReport.SetParameters(new ReportParameter[] { jobHourlyRateParameter });

            string reportType = "PDF";
            string mimeType;
            string encoding;
            string fileNameExtension = "pdf";
            Warning[] warnings;
            string[] streams;
            var renderedBytes = localReport.Render(reportType, "", out mimeType, out encoding, out fileNameExtension, out streams, out warnings);
            Response.AddHeader("content-disposition", "attatchment; filename=Contract." + fileNameExtension);

           MemoryStream stream = new MemoryStream(renderedBytes);

           myMessage.AddAttachment(stream, "Contract.pdf");


            var apiKey = "key removed for this post";
            var transportWeb = new Web(apiKey);
            transportWeb.DeliverAsync(myMessage);

            Contract contract = new Contract();
            contract.StudentId = studentId;
            contract.CompanyId = companyId;
            contract.CVR = companyCVR;
            contract.ApplicationId = applicationId;
            contract.IsSigned = true;

            db.Contracts.Add(contract);
            db.SaveChanges();
            return RedirectToAction("Index", "Projects");
        }

如果我运行它在本地主机上运行，则成功发送带有报告文件的邮件。部署到 Azure 时，它不再有效。注释掉报告生成并将其添加为附件使其有效，因此我确定问题出在报告生成周围。

什么可能导致它不再在网站上工作？我已经检查了参数不为空。

Answer 1

我打开 web.config 中显示的错误，如下所示：

<customErrors mode="Off">

然后我得到错误：

Could not load file or assembly 'Microsoft.ReportViewer.ProcessingObjectModel, Version=10.0.0.0, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a' or one of its dependencies. The system cannot find the file specified.

感谢 Crowcoder，我终于找到了问题所在，我不得不从 NuGet 包管理器安装 Microsoft.Report.Viewer 10.0.0！

构建、发布，现在可以使用了！
