I get a error when after I published the app. Even on the same computer that I devolved on. While developing everything worked fine.

The system cannot find the path specified.

I tried this https://stackoverflow.com/a/14602748/10852981 and I cant figure out where to add this in my mvc app. I checked the permissions on the files and allowed to everyone. I included the .rpt file in project. Im not sure what else i should do.

This is the code I have for downloading the file

public static void GenerateReportInPDF(DataTable tb, string reportName)
        {
            using (var reportDocument = new ReportDocument())
            {
                var reportPath = HttpContext.Current.Server.MapPath("~/") + "Reports//" +  reportName;
                reportDocument.Load(reportPath);
                reportDocument.Database.Tables[0].SetDataSource(tb);             

       reportDocument.ExportToHttpResponse(ExportFormatType.PortableDocFormat, HttpContext.Current.Response, false, reportName);
                reportDocument.Close();
            }
        }

This line ProductionTracker.Web.Reports.CrystalReportGenerator.GenerateReportInPDF(DataTable tb, String reportName) in C:\Users\barry\source\repos\ProductionTracker.Web\ProductionTracker.Web\Reports\Controller\CrystalReportGenerator.cs:37 looks wrong because its from my development repo. But im not sure what to do about it.

    1) The error you are getting and the error you referenced in the other SO post are not the same error. 2) Are you 100% sure that the `reportPath` variable is returning the path that you think it should be and its the correct path to the report file? Are you 100% sure the report file is being deployed as part of the project (as in, you can physically see the file on your web server and its path is correct)? – Tommy Jul 01 '19 at 16:19

    Thanks that was the issue! I realized that once you save to output it saves it in the bin folder. So i added `/bin` then it worked – barryDev Jul 02 '19 at 17:25

    Glad it worked out for you! btw - you can mark your own answer as correct (I think after some period of time). That way the question is marked closed :) – Tommy Jul 03 '19 at 21:23

I finally solved it. The reason i had the error was because it was saving it to the bin folder once published. So i needed to change the path accordingly. I added /bin/ to
var reportPath = HttpContext.Current.Server.MapPath("~/") + "Reports//" + reportName; Like this var reportPath = HttpContext.Current.Server.MapPath("~/bin/") + "Reports//" + reportName; Then it worked!
