试图设置此报告中未定义的报告参数 'studentSignDateParameter'

Question

所以我正在生成一个包含参数的报告。

    ReportParameter cvrParameter = new ReportParameter("cvrParameter", companyCVR);
    ReportParameter companyNameParameter = new ReportParameter("companyNameParameter", company.CompanyName);
    ReportParameter companyAddressParameter = new ReportParameter("companyAddressParameter", company.Address);
    ReportParameter companyCityParameter = new ReportParameter("companyCityParameter", company.City);
    ReportParameter studentCityParameter = new ReportParameter("studentCityParameter", student.City);
    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);
    ReportParameter studentSignDateParameter = new ReportParameter("studentSignDateParameter", DateTime.Today.ToString("dd/MM/yyyy"));
    ReportParameter companySignDateParameter = new ReportParameter("companySignDateParameter", contractobj.CompanySigningDate);
    ReportParameter companyRepNameParameter = new ReportParameter("companyRepNameParameter", contractobj.RepFirstName +" "+contractobj.RepLastName);
    ReportParameter projectWorkFromParameter = new ReportParameter("projectWorkFromParameter", projectobj.WorkFrom);


    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 });
    localReport.SetParameters(new ReportParameter[] { studentSignDateParameter });
    localReport.SetParameters(new ReportParameter[] { companySignDateParameter });
    localReport.SetParameters(new ReportParameter[] { companyRepNameParameter });
    localReport.SetParameters(new ReportParameter[] { projectWorkFromParameter });
    localReport.SetParameters(new ReportParameter[] { companyCityParameter });
    localReport.SetParameters(new ReportParameter[] { studentCityParameter });

参数如上所示从控制器设置。

我已将所有参数添加到我的报告数据中，其他一切正常，但 'studentSignDateParameter'。

试图从参数的属性中指定它是一个日期，但我得到了相同的结果。 "companySignDateParameter" 工作正常，它是一个日期字符串。

我也试过给参数一个随机值，一个字符串或其他什么，但这个错误仍然存在。我认为这与代码无关，因为 Visual Studio 未检测到任何错误。

有什么想法吗？该参数可能有什么问题？我删除了它并重新制作了它，但没有任何变化。
