Report in c#

Question

I’m trying to develop a report(report) in C# and using the ReportViewer for display. I am using the SGBD Postgresql, and I’m unable to make the connection to the database and the report, to get the data because an error occurs when I add the dll of Postgresql ODBC, I’ve tried everything and still can’t add to dll appearing the following message:

"A Reference to could not be Added. Please make sure that the file is accessible, and that it is a Valid Assembly or COM "

so since I can’t execute the report this way I thought of an alternative medium.

I wonder if there’s any way I could pass one DataTable with the information I want to be displayed to the report and there he display and if yes how can I do that?
