Crystal 在 ASP.net Mvc 应用中的 IIS 中部署应用程序时无法加载报告

我在发布应用程序后遇到错误。即使在我下放的同一台计算机上。虽然开发一切正常。

我试过这个但我不知道在我的 mvc 应用程序中添加它的位置。我检查了文件的权限并允许所有人。我在项目中包含了 .rpt 文件。我不确定我还应该做什么。

这是我下载文件的代码

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();
            }
        }

这一行ProductionTracker.Web.Reports.CrystalReportGenerator.GenerateReportInPDF(DataTable tb, String reportName) in C:\Users\barry\source\repos\ProductionTracker.Web\ProductionTracker.Web\Reports\Controller\CrystalReportGenerator.cs:37 看起来不对，因为它来自我的开发回购。但是我不知道该怎么办。

我终于解决了。我有错误的原因是因为它在发布后将其保存到 bin 文件夹中。所以我需要相应地改变路径。我将 /bin/ 添加到
var reportPath = HttpContext.Current.Server.MapPath("~/") + "Reports//" + reportName; 像这样 var reportPath = HttpContext.Current.Server.MapPath("~/bin/") + "Reports//" + reportName; 然后成功了！
