Rendering .rdlc reports with ASP .NET Core

Question

Is it possible to render .rdlc reports with ASP.NET Core? Currently this only seems to be possible if I target the .NET Framework as opposed to .NET Core.

I don't need a report viewer I just need to render the results of an .rdlc report as a byte array.

Answer 1

In case anyone is still looking for a similar solution, I would recommend using "ReportViewerCore.NETCore".

Here is the nuGet reference - https://www.nuget.org/packages/ReportViewerCore.NETCore/

Here is the github link to the repo - https://github.com/lkosson/reportviewercore/

Basic usage

Stream reportDefinition; // your RDLC from file or resource
IEnumerable dataSource; // your datasource for the report

LocalReport report = new LocalReport();
report.LoadReportDefinition(reportDefinition);
report.DataSources.Add(new ReportDataSource("source", dataSource));
report.SetParameters(new[] { new ReportParameter("Parameter1", "Parameter value") });
byte[] pdf = report.Render("PDF");

Answer 2

If you want to create pdf/excel/word using rdlc report I recommend you can use AspNetCore.Reporting library. This is open source and comes as a nuget package. you can integrate this in your .NET Core API or .NET Core Azure function. You can generate a byte array convert it to base 64 string and retrieve that to your client side. More on the link in the comment.
