如何从Entity Framework中的存储过程获取DataSet数据

Question

I'm using Entity Framework with asp.net.

I add the my database and stored procedure to the ADO.net entity data model.

I want get data from the stored procedure preprocessed as DataTable. I create the function import.

and I call it like this

DataTable user= db.f_GetbyUser((Guid)User.UserId);

But there is error and it says

Cannot implicitly convert type 'System.Data.Objects.ObjectResult' to 'System.Data.DataSet'

So can you please tell me how can I run the stored procedure and get the data as data set

Answer 1

There is no direct conversion. You have to either loop thru result and populated datatable/dataset manually in the loop or use the same connection but in real ADO.NET Command object/Adapter objects to fill Dataset.

But you shouldn't really be needing Datasets in EF Project, if you do use EF - use strong types it generates for you.

Answer 2

You're mixing technologies here. As @yuriy-galanter says, it is technically possible if you hack the data in to a DataSet / DataTable yourself, but you need to reconsider your data access approach and opt for either DataSets, EF (or something even better).
