即使我在代码中设置了参数,我仍然收到必须设置参数的错误。我已经运行探查器来查看传递给 SSRS 的内容,探查器指示参数 = null。然而,所有这些都是在代码中设置的。有人有想法么?代码如下:
string strReportPath;
Microsoft.Reporting.WinForms.ReportParameter prmFranchiseOID;
Microsoft.Reporting.WinForms.ReportParameter prmSchoolOID;
Microsoft.Reporting.WinForms.ReportParameter prmRoomOID;
Microsoft.Reporting.WinForms.ReportParameter prmOrderDate;
Microsoft.Reporting.WinForms.ReportParameter prmLanguage;
Microsoft.Reporting.WinForms.ReportParameter prmContrast;
List<Microsoft.Reporting.WinForms.ReportParameter> prms = new List<ReportParameter>();
byte[] pdf = null;
try
{
prmFranchiseOID = new Microsoft.Reporting.WinForms.ReportParameter("FranchiseOID", "8D126AA2-2E5C-4B2B-8D19-167027F8C7D8");
prmSchoolOID = new Microsoft.Reporting.WinForms.ReportParameter("SchoolOID", "96FEE335-0CB9-413A-9DDC-78F8C67770C4");
prmRoomOID = new Microsoft.Reporting.WinForms.ReportParameter("RoomOID", "null");
prmOrderDate = new Microsoft.Reporting.WinForms.ReportParameter("OrderDate", DateTime.Now.AddDays(1).Date.ToString());
prmLanguage = new Microsoft.Reporting.WinForms.ReportParameter("Language", "en-CA");
prmContrast = new Microsoft.Reporting.WinForms.ReportParameter("Contrast", "true");
prms.Add(prmFranchiseOID);
prms.Add(prmSchoolOID);
prms.Add(prmRoomOID);
prms.Add(prmOrderDate);
prms.Add(prmLanguage);
prms.Add(prmContrast);
// Note: For Account Holder users, their specified report folder is "/LunchLady/User".
strReportPath = "/LunchLady/Franchise/" + urlReportName;
try
{
rvReport.ServerReport.ReportServerUrl = new System.Uri("https://testsql.thelunchlady.ca/ReportServer");
rvReport.ServerReport.ReportPath = strReportPath;
rvReport.ServerReport.SetParameters(prms);
string ReportType = "PDF";
pdf = rvReport.ServerReport.Render(ReportType);
谢谢
